Defensive Zone Coverage

Rule set: Written to NHL rules. Where IIHF, USA Hockey or typical rec-league rules differ in a way that changes how you play, it is flagged inline. Playing in Britain? The IIHF flags are yours — every level of UK hockey runs the IIHF book, amended locally; see UK and England Rules.

Key focus

Find out which system your team plays. Coverage is the most system-dependent part of hockey. The fastest question: when the puck is in your corner, does the winger stay at the blue line or come down to help?

Never move the puck across the front of your own goal — not with a pass, not by skating it. Go behind your net, where an interception costs little. Some teams exchange high above the circles instead, so ask which route yours wants.

Defend the middle before the outside. Take away the pass into the slot before the shot from distance. A point shot is a save your goalie expects; a pass into the slot is not.

Be goal side — between your man, or your area, and your own net. Angle an attacker toward the boards rather than reaching across your body: reaching turns you, and a turned defender is beaten half a second later.

Somebody must always have the doorstep — the edge of the blue paint — and both defencemen must know who. The classic breakdown is both of you on the same puck. Say it: "I've got them, you've got the net."

Take away the next pass, not the puck. Hold your area, or your man in a man system, with your stick flat in the lane. In a scramble the most dangerous player is almost never the one with the puck.

Talk early — say what you are about to do, not what you can see. "I've got the corner, you have the net" settles who has whom. The moment you do not know who is yours, go to the middle.

Own the net front with position, never with a push. Get there first, inside shoulder ahead. As the puck arrives, lift their stick low on the shaft, up not sideways, then let go — never on into their head. Never walk a screener off their spot or shove anyone into your goalie.

Decide where the puck is going before it is yours, then leave as a group. Scan while the battle is on: winger, centre or glass. Puck out before your third forward, unless your breakout sends a forward early.

Overview

Key: Coverage is the agreement your five skaters have about who protects what when the other team has the puck in your end
Convention: The most system-dependent part of hockey — two good teams can play completely different systems and both be right
Risk: The same instruction — "get to the corner", "stay high" — can be correct on one bench and a firing offence on the next
Action: Work out which system your team plays, so you stop guessing
Never: Move the puck across the front of your own goal, with a pass or with your feet — go behind your own net instead, where an interception costs you almost nothing
Position: Be goal side — between your man, or your area, and your own net. An opponent between you and your goalie means you are defending nothing

Coverage is the agreement your five skaters have about who protects what while the other team has the puck in your end. The same instruction can be right on one bench and a firing offence on the next, which is why knowing your system comes first. Whether the winger stays high or comes down when the puck is in your corner separates the two main families.

The most dangerous chances come from a small area in front of your net — roughly from the posts out to the faceoff dots and up to the tops of the circles. A shot from inside it is worth several times one from outside (Shooting covers the values, Rink Map the shape). Every system keeps bodies between that area and the puck, which is why you take away the pass into it before the shot from distance.

The player who scores from close in is standing on the doorstep, so somebody has to be there. Who it is changes with the system; that it is somebody never does.

In a collapse, the weak-side winger decides whether the system works. When the centre goes down into the strong-side corner, the high slot empties, and the seam, the back-door pass and the low-to-high shot all run through it. So the weak-side winger drops into it and climbs back the moment the puck leaves the corner. Only that winger: if both sag, one point-to-point pass gives the other team a free walk-in. Under man-on-man the wingers follow their checks down instead.

Once you win the puck, your five are turned to leave. An interception in the slot puts an opponent on the most dangerous ice, in front of a goalie who has just moved across; picked off behind your net, the opponent has no angle. That is why nothing goes across the front of your goal, and why you choose the target before the puck arrives.

Most defensive-zone breakdowns are not effort failures. Usually both players worked hard, on different assumptions about who had whom. That is coaching consensus rather than a measured fact — public tracking counts the play the offence made, not the defensive breakdown (Neutral Zone Systems covers what it counts). Talking early is the cure.

The Problem Every System Solves

In short: Protect the house first and choose which chances to give up, while keeping someone ready for the outlet.

Key: The most dangerous chances come from the house, or home plate — the two goalposts widening to the faceoff dots and up to the top of the circles
Convention: The house is an analytics convention rather than an official marking — Shooting covers what a shot from inside it is worth, Rink Map covers the shape
Goal: Allocate five bodies so the house is never open, while still being able to take the puck off them and leave
Priority: Choose which chances you are willing to give up — coverage is not about eliminating them
Risk: With all five packed onto the goal line nobody is available for the outlet — you win the puck and give it straight back
Key: Twenty point shots through no traffic and zero back-door tap-ins is a good night

Five of you. Five of them. One net.

But the ice is not equally dangerous. The most dangerous chances come from a small area in front of your net, known as the house or home plate — the region bounded by the two goalposts, widening out to the two faceoff dots, and up to the top of the two faceoff circles. Draw those lines and you get a shape like a baseball home plate. That's the area that matters.

The house, or home plate — the region every defensive-zone system exists to protect: bounded by the two goalposts, widening to the end-zone faceoff dots and up to the tops of the circles. Nothing here is painted on the ice; the circles, dots and crease that fix its corners are.

What the shapes and fills mean

Two honest qualifications. The boundaries are an analytics convention, not an official marking — Natural Stat Trick, Evolving Hockey and MoneyPuck each draw them slightly differently. And how much of the scoring it accounts for depends on whose figure you take; Shooting covers the values and hedges every one.

The counted figures are more modest than dressing-room versions: 26.8% of NHL goals came within two stick-lengths of the net and 51.6% within twenty feet, from the 2,498 goals with coordinates in 400 games of the 2024-25 NHL play-by-play feed (Body Contact and Battles covers both; those patches are smaller than the house). What every source agrees on is the ratio: a shot from inside this area is worth several times the same shot from outside it. That is enough to build a system on.

Some vocabulary, used consistently throughout this document and the rest of this guide (full definitions in Rink Map):

The slot — the lane in front of the net between the two faceoff circles.
The high slot — the upper part of it, from the faceoff dots up to the top of the circles.
The goalmouth — the immediate front of the net, the doorstep. Distinct from the slot; this is where tap-ins and deflections happen.
The crease — the blue paint the goalie works in. Under NHL rules it is eight feet wide (one foot outside each post) and six feet deep at its deepest point.
The point — the area just inside the blue line where the opposing defencemen stand. An area, not the line itself.
The half-wall — the boards roughly level with the faceoff dot, between the corner and the point.
Strong side — the side of the ice the puck is on. Weak side — the other side.
Low — nearer your own goal line. High — nearer the blue line.

So the actual problem is: how do you allocate five bodies so that the house is never open, while still being able to take the puck off them and leave?

Every system is a different answer, and every answer costs something. There are only five of you, and if you put four in the house then somebody at the point is unmarked. Defensive zone coverage is not about eliminating chances — it is about choosing which chances you're willing to give up. A team that concedes twenty point shots through no traffic and zero back-door tap-ins has had a good night.

There is one more constraint people forget. You are not only defending; you are trying to leave. A shape that packs all five players onto the goal line protects the house beautifully and has nobody available to receive an outlet pass, so you win the puck and immediately give it back. Every system trades net-front safety against breakout readiness. Keep that tension in mind — it explains most of the design decisions below.

What Stays True Across Every Coverage System

In short: Whatever the system: defend the middle first, stay goal side, and make sure somebody always has the goalmouth.

Priority: Defend the middle before the outside — it tells you which chance to concede, not which square metre to stand in
Position: Stay on the defensive side of the puck — between your man, or your area, and your own net
Key: Somebody must always have the goalmouth — the doorstep, not the slot; the person changes, the requirement never does. Never both defencemen on the puck without knowing who has taken it
Technique: Sticks flat in the passing lanes — when you cannot reach the puck you can almost always reach the lane
Action: Box out at the net front, inside shoulder ahead. As the puck arrives, lift their stick low on the shaft, well below the bottom hand, then let go. Never sideways or into their head; never cross-check
Rule: Do not count on 69.1 against a screen — its positioning limb sits under a "should be disallowed only if" ceiling, and NHL, PWHL and IIHF 2026/27 Table 14 answer "Goal is allowed" at 5C and 5E for an outside-the-crease screen impairing your goalie. Beat it by position, never by moving them
Rule: Under USA Hockey and Hockey Canada beat a screen outside your crease by position, never by moving them, which can be called interference. Hockey Canada's goalkeeper-interference rule does not reach it; USA Hockey 617(c)(4)'s "interfering with the goalkeeper" is undefined
Rule: Inside the paint the two books split — USA Hockey 625(b) does not ask who scored but lifts if the puck preceded them in or the goalie is out of the crease area; Hockey Canada 8.5 lifts if the puck is already in it, or the crease player stays passive and clear of the goalie's view and movements
Rule: Shoving an attacker into your crease does not disallow the goal — USA Hockey 625(b) allows any legal goal where a defending player's physical interference put them there; Hockey Canada Interpretation 2 to 8.5(a) also penalises the defender who committed the initial foul, under the appropriate rule
Never: Shove an attacker into your own goalie — it can be called interference in every book, and the attacker arrives backwards onto a goalie who is down, square to the shot and unable to see them coming
Action: Talk, and talk early — "I've got the corner", "you have the net", "switch", "back door"

These hold no matter what system your coach runs. If you remember nothing else, remember these.

1. Defend the middle before the outside. A shot from the point through clean ice is a save your goalie expects to make. A pass into the slot is not. Given the choice, take away the pass. You are steering the puck to where it is least dangerous, not trying to touch it everywhere.

This principle does not dictate where your feet go — the system does that. Under low zone collapse you sag toward the middle, and the middle stays full because everybody stands in it. Under man-on-man you follow your check to the boards, and the middle stays protected because the man who would take the seam pass has someone on them. Under a strong-side overload you abandon the weak side and squeeze the puck side, betting that no cross-ice pass gets through.

All three defend the middle first; only the first does it by standing there. So apply the principle by asking "which is the more dangerous option to leave open?", not by drifting to the slot in a system that told you to go with your man.

2. Stay on the defensive side of the puck. Be between your man (or your area) and your own net. Any time an opponent is between you and your goalie, you are defending nothing — you're just skating behind a play. This is why you angle attackers toward the boards rather than reaching across your body at the puck: reaching turns you, and a turned defender is on the wrong side a half-second later.

3. Never both defencemen on the puck without knowing who has the goalmouth. One defenceman engages, the other stays home. If both of you get sucked into the same corner battle, the goalmouth is empty and one pass beats your entire team. Coaches at every level name this as one of the commonest causes of goals against — coaching consensus, not a statistic — and talking prevents it.

What is invariant is that somebody is home — not that it is your partner. Under low zone collapse, the default this document assumes, it is the weak-side defenceman. Under man-on-man it is whoever's check went there; under a collapsing box both defencemen are inside the house; under Box+1 it is the two low players in the box; under the hybrid, whichever of the low three is matched to the net-front forward.

Under a strong-side overload some coaches put both defencemen low along the boards and hand the middle to a forward. That is one coaching account rather than anything counted, and what it gives the forward is the slot, not the goalmouth — a reason to ask, not to assume. So the rule is never both of you without knowing who has taken the goalmouth. Risk Management states the same principle.

4. Somebody must always have the goalmouth. Not "the slot" — the doorstep. The player who is going to score is the one standing at the edge of the blue paint with their stick on the ice. Under low zone collapse that is the weak-side defenceman; under man-on-man it's whoever's check went there. The person changes. The requirement never does.

5. Sticks in passing lanes, on the ice. An active stick lying flat in a lane takes away a pass without committing your body — which means you can still get to the next thing. A stick held off the ice or waving at hip height does nothing. When you cannot reach the puck, you can almost always reach the lane.

6. Box out at the net front. Get there first: your inside shoulder ahead of theirs, your body between them and the puck. As the puck arrives, lift their stick — ⚠️ never cross-check their back. Take it up rather than sideways, low on the shaft, well below the bottom hand, then let go — stopping at their stick rather than driving on into their head. Keep their skates on the ice — a player whose edges are gone cannot brace, or choose what meets the post first. Full technique in Defender and Body Contact and Battles.

Screening your own goalie is your problem, not the referee's. An attacker standing outside the crease in your goalie's sightline, without touching them, is normally doing something legal, and the referee will not move them for you. Take the sightline back with your body. ⚠️ Never walk the screener off their spot — that can be called interference wherever you play, and where checking is barred an illegal check as well.

Don't shove an attacker into your goalie hoping for a disallowed goal. An attacker pushed in by a defender has not caused that contact, so the goal generally stands, and the shove can be called on you. ⚠️ Hold your position, never push — the attacker arrives backwards onto a goalie who is usually down, square to the shooter and unable to see the attacker coming, with the post beside them. That injury risk is coaching caution: no source here counts injuries from it. Body Contact and Battles has the same collision for the player being shoved, and Goaltender has it from the goalie's side.

7. Talk, and talk early. "I've got the corner." "You have the net." "Switch." "Back door." Coverage is a shared model of who has whom; the only way to keep the model shared is out loud. See On-Ice Communication.

What it costs.

The stick lift. At or near the hands, three of the six books call a lift hooking. The IIHF does so on the location alone (55.1); its next sentence exempts stick-to-stick contact and the book leaves the tension unresolved, so low is still the answer. USA Hockey (623) and Hockey Canada (Interpretation 1 to 8.2(a)) call it hooking where it stops the opponent playing the puck. The NHL reaches a chop there as slashing (61.1). Above the hands, Hockey Canada escalates a lift whose accidental contact injures the head or neck: a double minor in Junior and Senior, and a mandatory major and game misconduct in minor and female hockey (7.6(b)). It makes a "pitchfork action in lifting the stick" that injures the head or neck a major and game misconduct.
The cross-check in the back. ⚠️ Lift the stick; never cross-check their back. No book here caps it at two minutes, a major ends your game in all six, and Hockey Canada and CARHA must give the major and game misconduct where it injures (9.2(b), 54(c)). Under USA Hockey a reckless one is a mandatory major and game misconduct (609(b)), so plan on a match and a likely multi-game suspension (602(a)).
The screen outside your crease. NHL and IIHF 69.1 and PWHL 71.1 do name positioning: a goal "should be disallowed only if" an attacker "either by his positioning or by contact, impairs the goalkeeper's ability to move freely within his crease or defend his goal" (NHL wording; the PWHL's says "her", the IIHF's "their" and "relevant contact"). But that "only if" is a ceiling, not a direction. All three then answer the outside-the-crease screen that impairs your goalie, Situations 5C and 5E, "Goal is allowed" (NHL Reference Table 14; IIHF Appendix IV Table 14, Table 16 in 2025/26 with identical rows; PWHL Table 14). The call is the referee's on-ice judgement, so treat that as what the text supports, not a prediction. Britain plays the IIHF's 69.1, which adds that the Referee "has the possibility to stop the game" if an attacker "is in the goal crease and does not leave immediately" — a possibility, and only inside the paint.
The screen outside your crease, under Hockey Canada and USA Hockey. Hockey Canada writes no provision about screening a goalie and makes the penalty turn on contact. USA Hockey's no-goal rule (617(c)(4)) says only "interfering with the goalkeeper", undefined, so don't count on it either way; its "protective screen" (625(a)(1)) is set on a checker.
The screener inside your crease. USA Hockey 625(b) is flat — no goal with an attacker in the crease unless the puck preceded the attacker or the goalie is out of it. Hockey Canada 8.5 allows the goal if the puck is already in the crease, or if the player in it does not play the puck, interfere with the play or obstruct the goalie's view or movements — and a screener standing in your paint is normally obstructing the view. Those negatives come from the two playing-rule books and USA Hockey's Casebook; no Hockey Canada casebook is held here. Rules Primer owns the full comparison.
The shove into your goalie. Under NHL and IIHF 69.1 and PWHL 71.1 an attacker pushed in by a defender has not initiated the contact, "provided the attacking player has made a reasonable effort to avoid such contact". USA Hockey gives the attacker more relief still: "play shall not be stopped and any legal goal scored shall be allowed", no proviso. ⚠️ And the shove can be a penalty on you in every book — interference (NHL and IIHF 56.2(i), PWHL 57.2(i), USA Hockey 625, Hockey Canada 8.3(a), CARHA 66(a)), or cross-checking with the stick in both hands. Hockey Canada's Interpretation 2 to 8.5(a) covers exactly this play: "The referee should also penalize the defending player who committed the initial foul under the appropriate rule."
A forward who runs your goalie is the referee's problem, not yours to answer. Hockey Canada 8.5(b) can reach a major and game misconduct on the violence of the contact with nobody hurt, mandatory for charging the goalie or for an injury, and 8.5(c) a match.

Low Zone Collapse (Zone Coverage) — the standard coverage

This is the system assumed throughout, and the one coaching material most often describes as taught first in North American minor, junior and rec hockey — again, consensus from coaching material, not a survey; no count of what teams run has been found. It is also frequently called sagging zone, zone coverage, or simply "the collapse". If your coach has never named the system, this is probably what they mean.

The idea: you defend space, not people. Each of the five of you owns an area. Whoever skates into your area becomes yours until they leave it. Three of you — both defencemen and the centre — live below the top of the circles, which matches their three forwards down there, while the two wingers hold the points so the opposing defencemen never get a clean seam pass into the middle. When the centre goes low to help, the weak-side winger sags into the high slot and you are briefly four down there. Only under maximum pressure — the collapsing box described later — do all five drop below the circles.

The base shape — puck in the strong-side corner

In short: Under low zone collapse one defenceman pressures the puck, the other owns the goalmouth, the centre adds a second body, and the wingers stay high.

Convention: Under low zone collapse, the strong-side defenceman is on the puck in the corner or behind the net — pressure and pin the puck, or angle them away from the net. Pin the puck, not the player
Convention: The weak-side defenceman owns the goalmouth and boxes out — do not get drawn to the puck
Convention: The centre is the second body into the strong-side corner battle — two on one wins it
Convention: The strong-side winger stays high on the strong-side point, between that defenceman and the net
Convention: The weak-side winger covers the weak-side point and collapses into the high slot when the centre goes low
Rule: In IIHF women's hockey, and so British women's hockey, pin the puck, not the player — Rule 101.1 bars using the boards to eliminate an opponent from the play, push her into the boards or pin her along them
Rule: Pin the puck only until help arrives, never for a whistle — under USA Hockey, a puck held against the boards is a minor by three seconds, help coming or not, pressured or not (Rule 632(b); Casebook Rule 632, Situation 6)
Rule: Outside USA Hockey a deliberate freeze is a minor — NHL 63.2(i), IIHF 63.2(I), PWHL 65.2(i); Hockey Canada 10.1(i) and CARHA 74(b) exempt a hold while "being checked by an opponent", but Hockey Canada 6.12(b) still penalises a freeze for a stoppage and CARHA 55(a) makes stalling a bench minor
Never: Arrive into the back of a player facing your end boards. Take the puck, take the ice, or angle them off it instead
Rule: Pull up on anyone digging at the wall. Hockey Canada 7.5: minor and game misconduct, major on violence, a must if hurt, match into boards or goal if defenceless; on the head, head contact (7.6; 7.7), up to a match; head first into boards or goal, the harsher of 7.5 and head contact
Rule: Never hit a turned back. On the head: Hockey Canada head contact, a match if defenceless; major and game misconduct a must on a high cross-check at any level, injury (7.6, minor and female), high violence or head injury off glass, ice or boards (7.7, Junior and Senior)
Rule: Pull up on a turned back — the NHL, PWHL and IIHF write no minor for a check from behind (43.2); the NHL and PWHL give a major and game misconduct (43.3, 43.5), and under the IIHF plan on its major and automatic game misconduct (43.3)
Rule: Never put a defenceless player into the boards — no book caps boarding at a minor (NHL, IIHF, PWHL 41; Hockey Canada 7.2; CARHA 49), and USA Hockey's floor adds a misconduct to its minor (603(a))
Rule: A USA Hockey game misconduct is not only this game — 404(b) also suspends the player for their team's next game, minimum two where imposed under 403(b); Hockey Canada 4.8(c) is automatic only in the last 10 minutes, overtime or after the game

Player	Where	Job
Strong-side defenceman	On the puck — corner or behind the net	Pressure and pin the puck, or angle them away from the net (see the note that follows)
Weak-side defenceman	Goalmouth	Own the doorstep. Box out. Do not get drawn to the puck
Centre	Low support, strong side	Second body into the corner battle — two on one wins it; the high slot is theirs whenever they are not down here
Strong-side winger	High, on the strong-side point	Between that defenceman and the net; block the shot with your head up and out of the lane
Weak-side winger	High, on the weak-side point — collapsing into the high slot when the centre goes low	Cover the point and the middle, in that order of movement

"Pin the puck, not the player." Pinning the puck against the wall with your skate or stick is how you stop it going the wrong way; pinning the opponent is something else, and Body Contact and Battles covers the difference. Hold the pin only until the second body arrives to dig it out — never for a whistle, never past three seconds under USA Hockey, and never by falling on it or gathering it into your body.

The second half of "pin the puck, not the player" is how you arrive. If you are the second body into a corner battle, arrive on the puck or on the ice your opponent wants — never on their back. They are facing your end boards with their head over the puck and cannot see you coming, so ⚠️ if you can see their numbers, pull up, put your stick on the puck and angle them off it. That is the whole instruction: take the puck, take the ice, or angle them off it — never finish into a back.

Note that the two forwards' jobs are asymmetric. The strong-side winger holds their point; the weak-side winger is the flex player who covers two areas depending on what the centre is doing. That is the defining feature of the system, and the reason it is sometimes called a sagging zone.

What it costs.

Pinning the player. In this system, pin the puck, not the opponent. In women's hockey it is also a rule: IIHF Rule 101.1 prohibits using the boards to eliminate an opponent from the play, push her into the boards, or pin her along the boards.
Freezing the puck. Pin it only until help arrives, never for a whistle — and under USA Hockey, never past three seconds. Falling on it or gathering it into your body is a minor in every book, and a penalty shot when the puck is in your own crease — under Hockey Canada, whenever you are. Under USA Hockey the clock is the penalty, not your reason: more than three seconds against the boards is a minor, and "The fact that the player may or may not have been pressured by their opponent has no bearing on the call" (632(b); Casebook Rule 632, Situation 6). Hockey Canada 10.1(i) and CARHA 74(b) exempt a player "being checked by an opponent", but Hockey Canada 6.12(b) still penalises making the puck unplayable "in order to gain a stoppage of play". CARHA 55(a) is a bench minor for "deliberately delaying the game in any manner", its Note 2 naming "freezing the puck". Body Contact and Battles sets out every book.
The hit from behind, under Hockey Canada. ⚠️ Pull up — Rule 7.5 is written for this picture: a player "with their head down looking for the puck or 'digging the puck out,'" hit from behind and driven head first into the boards, with the onus on the player delivering the check. Even the floor ejects you: a minor and a game misconduct, anywhere on the ice (7.5(a), (e)). Above it: a major and game misconduct on the violence, mandatory if they are hurt (7.5(b)), and a match where they go into the boards or goal frame "unable to protect or defend themselves", or where you deliberately tried to injure them (7.5(c)).
Once it reaches the head, under Hockey Canada. ⚠️ Keep the hit off the head — there it is head contact, because Rule 7.6 "supersedes any other rules" except fighting. In minor and female hockey (7.6) it runs from a minor — a third in one game ejects — up to a major and game misconduct on the violence alone, mandatory if they are hurt or it was a cross-check above the shoulders. It is a match if they could not protect themselves or you tried to injure them. In Junior and Senior (7.7) it is a major and game misconduct at a high degree of violence, for a cross-check above the shoulders, or where their head is driven into the glass, ice or boards and injured, and a match on the same two grounds. Driven head first into the boards or goal frame, plan on the harsher of 7.5 and the head-contact rule.
The hit from behind, elsewhere. Pull up — the NHL, the PWHL and the IIHF write no minor for it (43.2). The NHL and PWHL give a major and game misconduct (43.3, 43.5); under the IIHF, plan on the same (43.3), because its Glossary counts a check on a skater without the puck who cannot see it coming as reckless. On the head, all three charge the harsher of Rules 43 and 48. CARHA ejects at every tier — a minor or a major, each with a game misconduct, the major a must if they are hurt and bringing at least a one-game ban (32(d)) — and a hit into the boards or goal net on a player unable to protect themselves is a match (53(a), 53(b)). Body Contact and Battles → Checking from behind has every tier.
The hit from behind, under USA Hockey. ⚠️ Pull up here too — the softer floor does not reach this play. 608(a) starts at a minor plus a misconduct, which is not an ejection (404(a)), but its Casebook, Rule 608, Situation 1, requires the major plus a game misconduct, or the match penalty, "⁠[i]n every instance where a player forcefully checks an opponent who is standing along the boards (back toward the middle of the ice)". It requires the same where they are "thrust head first into the boards or goal frame", and where the check recklessly endangers them. For a reckless one, plan on a match and a likely multi-game suspension (602(a)), and 608(c) says a match "shall be assessed" where the check comes "with excessive force while the opponent is in a vulnerable or defenseless position". The same entry names the ice it worries about, the "“danger zone,” which is the area approximately ten feet out from the boards" — the corner, the half-wall and the wall side of the net front.
The next game. ⚠️ An ejection can cost you the next game too. Under USA Hockey 404(b) any game misconduct also suspends you for your team's next game — at least two where it came from a second major (403(b)). CARHA suspends for at least one game where the game misconduct comes with a major, unless it was for an accidental high stick (32(d)). Hockey Canada suspends automatically only for one in the last 10 minutes, overtime or after the game (4.8(c)), and the NHL and PWHL only at a second game misconduct in their Physical Infractions category (23.6). The IIHF writes no count of its own. ⚠️ At a club in England or Wales, outside the Elite League, a game misconduct for checking from behind or a check to the head, or a major for boarding, is at least a one-game ban, in every league or age group you are registered in; in the Elite League, its Department of Player Safety decides (Casebook Rule 28). UK and England Rules has the full tariff. Body Contact and Battles and Rules Primer own the full comparison; no Hockey Canada casebook is held here to compare.
Boarding. ⚠️ Pin the puck, never the player, against the boards. Checking a defenceless opponent into them is boarding, and no book here caps it at a minor. USA Hockey never gives the minor alone (603(a)) and makes a reckless one a mandatory major and game misconduct (603(b)), so plan on a match and a likely multi-game suspension (602(a)). Body Contact and Battles → Boarding has every tier.

The rotations

Convention: In the collapse, coverage is a set of positions that swap as the puck travels, not jobs bolted to people
Convention: Corner to behind the net — the defencemen exchange roles at the midline; call it, "I've got them, you've got the net"
Convention: Corner to up the strong-side wall — the strong-side winger comes down the wall to between the hash marks and the goal line and takes it; that is your breakout starting, not a corner battle
Convention: Low to high — everyone climbs a level: wingers close on their points, the centre steps up into the high slot, the defencemen recover to the net front and low slot
Convention: Point to point — both wingers slide across and the shape shifts as a unit; nobody chases across the middle at speed
Convention: Puck to the far corner — the defencemen exchange again, the centre follows it low, and the wingers swap flex roles

Coverage is a set of positions that swap as the puck travels, not a set of jobs bolted to people.

Puck moves corner → behind the net. The strong-side defenceman follows it to the post and hands it off at the midline. The other defenceman is now the strong-side defenceman and takes the carrier as they emerge; the first one slides back to the goalmouth. You have exchanged roles without either of you ever leaving the net unattended. Call it: "I've got them, you've got the net."
Puck moves corner → up the strong-side wall. The strong-side winger engages it. That is not a corner battle — that is the start of your breakout, and it is the one time in this system a winger comes off the point voluntarily. They come down the wall to between the hash marks and the goal line and take the puck there; the point coverage they are leaving is finished, because the other team no longer has the puck. Take it. See Breakouts.
Puck goes low → high, to the point. Everyone climbs a level. The wingers close on their points, the centre steps up out of the low battle into the high slot, the defencemen recover to the net front and the low slot, and shooting lanes get filled.
Puck moves point → point across the top. Both wingers slide across with it and the whole shape shifts a few feet toward the new strong side. Nobody chases across the middle at speed; you shift as a unit.
Puck moves to the far corner. The defencemen exchange again, the centre follows the puck low, and the wingers swap flex roles — the new weak-side winger becomes the one who collapses.

The weak-side winger's collapse — the moment that decides the system

Convention: When the centre goes down to help in the corner, the weak-side winger drops off their point into the high slot to fill it
Action: Climb straight back up to the point as soon as the puck comes out of the corner
Action: Anyone with a clear view calls it — the centre, the weak-side defenceman, or the winger; don't wait to be told
Never: Both wingers sag at once — the point-to-point pass across the top then gives their defenceman a free walk-in
Read: If your weak-side winger has already followed the opposing defenceman down off the point, the collapse is not available — the defencemen or the centre must cover the high slot instead

When the puck goes into the strong-side corner and the centre goes down to help, the high slot is momentarily empty, and it cannot stay empty. So the weak-side winger drops off their point into the high slot to fill it. As soon as the puck comes out of the corner, that winger climbs straight back up to their point.

The high slot is not the most dangerous ice on the rink — that is the inner slot, nearer the crease. Shooting has close to half of NHL goals coming from the inner slot against just over a quarter from the outer slot, which is the band called the high slot here — a three-year, five-on-five Sportlogiq sample that is not public, so nobody outside Sportlogiq can check it. What makes this the moment the system turns on is that the high slot empties by design and the seam runs through it: the back-door pass crosses it and a low-to-high shot can come from it.

Low zone collapse — the standard coverage assumed here, one of several a team might play — at the instant the puck goes into the strong-side corner. Both wingers stay high on the points; the centre leaves the high slot to go down as the second body and make it two on one. ⚠️ The second body is the one that arrives late and unseen, and this carrier has the puck at their stick against the boards, with their back to the ice. Arrive on the puck, or on the ice the carrier wants, or angle them off it — never into their back. No book prices a check from behind at two minutes alone: under the NHL, the IIHF and the PWHL there is no minor for it at all, so the floor is a major and an ejection. ⚠️ And pin the puck, not the player — two on one is about outnumbering the battle, not joining a pin, and in IIHF women’s hockey pinning an opponent along the boards is an illegal hit. This is frame one of two, not a shape to hold. Under man-on-man or a hybrid these five would be reading bodies, not areas. Ask your coach which your team plays.

What the shapes and fills mean

A low zone collapse a beat after the corner battle begins — one of several systems — and the weak-side winger’s collapse is where it succeeds or fails. The centre is the second body in the corner, arriving inside the carrier and not behind them, because that carrier is facing the boards and cannot see the centre coming. The weak-side winger has dropped into the high slot; the strong-side winger holds their point, because if both sag the point-to-point pass gives their defenceman a free walk-in. The weak-side point is briefly unmarked on purpose: this system concedes point shots. The rotation is not available if that winger has already followed their own man down off the point.

What the shapes and fills mean

Two things to get right:

Anyone with a clear view calls it — the centre going down, the weak-side defenceman who can see the whole picture, or the winger themselves. Don't wait to be told; the rotation is late by the time somebody realises it's missing.
Only the weak-side winger does this. The strong-side winger holds their point. If both wingers sag, the point-to-point pass across the top gives their defenceman a free walk-in.

There is one situation where the collapse isn't available: if the weak-side opposing defenceman has already come down off the point and your weak-side winger has followed them, that winger is committed. Then the high slot has to be covered by the two defencemen being more vigilant about arrivals, or by the centre choosing not to commit fully to the corner. Read it and call it.

What low zone collapse is good at

Goal: Protect the middle by construction — you don't have to make good reads for the house to be full
Key: The easiest system to learn, because the areas are fixed even when the play is chaotic
Action: Let them cycle — grinding the wall spends their energy in the least valuable ice while you sit in the most valuable
Mindset: Area coverage doesn't ask a tired player or a mismatched winger to win a footrace
Position: Both wingers are already high — two outlets the moment you win the puck

It protects the middle by construction. You don't have to make good reads for the house to be full; standing in the right place does most of the work.
It is the easiest system to learn. Areas are fixed, so you always know roughly where to be even when the play is chaotic.
It is very hard to beat by cycling. Teams that grind the puck along the wall and behind the net are working in the least valuable part of the ice while you sit in the most valuable part. Let them cycle. They're spending energy on the perimeter.
Area coverage handles fatigue and mismatches. When you're tired, or a fourth-line winger is on with their top centre, it doesn't ask you to win a footrace.
The wingers are already positioned to break out. Two forwards high means two outlets the moment you win the puck.

Low Zone Collapse: What it concedes

Key: The walk-down, not the point shot, is the system's actual weakness — every collapse team needs an explicit answer to it
Countered by: The opposing defenceman skating down into the top of the circle, roughly halving their distance to the net while a winger guards an area rather than a man
Countered by: The seam between areas — skilled attackers stand where each defender assumes the other has them
Risk: Point shots, conceded on purpose — the bargain gets worse against a defenceman with a genuine shot
Risk: Extended possession — you are waiting for a mistake, and against a patient team that means tired legs

Point shots. Unapologetically. The bargain is that a shot from 55 feet with a stick in the lane is one your goalie should have — and that you'd rather concede it than concede a seam pass. The bargain gets worse as the shooting gets better; at higher levels, and against a defenceman with a genuine shot, "let them shoot" is a real cost.
The walk-down from the point. This is the system's actual weakness, not the point shot. If the opposing defenceman doesn't shoot from the blue line but skates down into the top of the circle, a zone winger who is guarding an area rather than a man will often let them go. The top of the circle is about 35 feet from the goal line (the end-zone faceoff spots sit 20 feet out, and the circles have a 15-foot radius). So they have roughly halved their distance to the net without anybody touching them, and from there they can shoot or feed the slot. Every collapse team needs an explicit answer to this (see Defending Specific Threats).
Extended possession. You will spend long shifts in your own end. You are not generating turnovers; you're waiting for a mistake or a loose puck. Against a patient team this means tired legs and eventually a breakdown.
The seam between zones. Skilled attackers deliberately stand between two defenders' areas, where each assumes the other has them. Zone coverage's blind spot is the player nobody feels responsible for.

Man-on-Man

Every player is assigned an opponent and covers that opponent everywhere in the zone. Your winger's opposing defenceman goes to the corner — you go to the corner. Their centre goes behind the net — your centre goes behind the net. Nobody is ever unmarked, because "unmarked" is not a state that exists in the system.

Assignments

Convention: Under man-on-man, both defencemen normally take the two most dangerous forwards — typically whoever is low and around the net
Convention: The centre takes the third forward, often the one supporting on the wall or in the slot
Convention: The two wingers take the two opposing defencemen and follow them, including down into the corner — the sharpest practical difference from low zone collapse
Action: Switch when two attackers cross, it is clean, and both of you call it out loud; stay when it isn't

Both defencemen normally take the two most dangerous forwards, typically whoever is low and around the net.
The centre takes the third forward, often the one supporting on the wall or in the slot.
The two wingers take the two opposing defencemen — and follow them, including down into the corner if they walk down. This is the sharpest practical difference from low zone collapse and the one that causes most confusion between teammates.
Switching is legal and necessary. When two attackers cross, the two defenders trade checks and say so out loud. The rule is usually: switch when it's clean and both of you call it; stay when it isn't.

What man-on-man is good at

Key: Nobody is ever unmarked — the seam problem zone coverage has simply doesn't exist
Goal: Generate turnovers — pressure everywhere means bad passes everywhere; zone coverage waits, man-on-man takes
Countered by: Nothing a cycle can do — if you are glued to a man, moving the puck to someone who beat an area creates nothing
Options: Match up — your best defensive forward can be put on their best player, all shift
Mindset: "They're yours" is the easiest instruction in hockey to understand, though not to execute

Nobody is ever unmarked. The seam problem that zone coverage has simply doesn't exist. Every attacker has someone within a stick length.
It is excellent against skilled cyclers and set plays. A cycle works by moving the puck to a teammate who has beaten the area — if you're glued to a man, the movement doesn't create anything.
It generates turnovers. Pressure everywhere means bad passes everywhere. Zone coverage waits; man-on-man takes.
It lets you match up. Your best defensive forward can be put on their best player, all shift.
Conceptually simple. "They're yours" is the easiest instruction in hockey to understand — though not to execute.

Man-on-Man: What it concedes

Countered by: Picks and screens — one collision the referee lets go and your man is gone with a two-stride head start
Risk: Mismatches — a winger in a footrace with a mobile defenceman has no help behind them
Risk: One beaten player leaves an attacker with the puck and nobody within twenty feet; every breakdown is immediately a high-danger chance
Risk: It is exhausting — a full shift at your opponent's chosen pace, in your own zone
Never: Follow your check into harmless ice while their teammate walks into the slot you vacated
Risk: Poor breakout readiness — when you win the puck, your five are wherever their five decided to stand

Picks and screens. Attacking teams beat man coverage by running players into your defenders on purpose — often interference, but not always called. One collision the referee lets go and your man is gone with a two-stride head start.
Mismatches. Your winger is now defending a mobile defenceman in a footrace. If they lose that individual battle, there is no help behind them, because everyone else is occupied.
Total collapse from one error. In zone coverage a beaten player leaves a hole; in man-on-man a beaten player leaves an attacker with the puck and nobody within twenty feet. Every breakdown is immediately a high-danger chance.
It is exhausting. You are skating a full shift — 30 to 80 seconds on the measured range, nearer 30–45 when it is well managed; Conditioning and Recovery covers both figures — at your opponent's chosen pace, in your own zone.
It pulls you out of the house. The classic failure is chasing a man into the corner who never had any intention of getting the puck, while their teammate walks into the slot you vacated. Good man-on-man teams have a rule about not following a check into harmless ice.
Poor breakout readiness. When you win the puck, your five players are wherever their five players decided to stand, which is rarely a breakout shape.

Coaching material has man-on-man much less common as a pure system than it used to be — coaching consensus rather than a count. Coaching resources are consistent that the removal of clutch-and-grab defending after 2004-05 made pure man coverage very hard to execute against modern speed and skill. What survives is the hybrid below.

Hybrid — man-on-man below the dots, zone above

In short: Below the dots take a body and stay with it, above them cover an area, and agree exactly where the line is.

Convention: Man-on-man below the dots, zone above them — some teams say the hash marks or the top of the circles, so learn your team's line
Convention: The two defencemen and the low forward, usually the centre, go man-on-man on the three attacking forwards: one on the carrier, one on the net front, one on the low support
Convention: The wingers play the points by area — but when your point man crosses the line and comes down, they become yours and you go with them
Convention: Below the goal line the low three stay locked on their men; when the puck comes back to the point, everyone releases and reverts to areas
Goal: Remove the walk-down and the unmarked net front while keeping the wingers high enough to break out
Risk: Two players on different sides of "are they below the dots yet?" is exactly the disagreement that produces a goal against
Options: "Man on the puck, zone off the puck" is the same family — man on the carrier anywhere, area coverage away from it

It is a deliberate compromise: man coverage where being unmarked is fatal, zone coverage where it isn't. Coaching material routinely calls it the most common arrangement in professional hockey, and increasingly common below it. No count of what teams run in this zone has been found, so treat that as coaching consensus. (The one team-level measure on record, KHL pass-clustering data described in Breakouts, is about a different phase of play.)

The rule of thumb: man-on-man below the dots, zone above them. Some teams say "below the hash marks" or "below the top of the circles" — the line varies by a few feet, so learn your team's version. Above that line, you cover an area and pass players off. Below it, you take a body and you stay with it.

How it plays out:

The two defencemen and the low forward (usually the centre) are effectively man-on-man on the three attacking forwards down low. One takes the puck carrier, one takes the net front, one takes the low support.
The two wingers play zone up high on the points — but with a man-on-man trigger: if your point man crosses the line and comes down, they become yours and you go with them. This is the direct fix for low zone collapse's biggest weakness.
When the puck goes below the goal line, the low three stay locked on their men rather than rotating by area, which kills cycles far more effectively than a pure zone.
When the puck comes back up to the point, everyone releases and reverts to areas, and the shape re-forms.

What it's good at: it removes the walk-down problem and the unmarked-net-front problem while keeping the wingers high enough to break out. It also degrades gracefully — if the low man coverage falls apart in a scramble, you can revert to "protect the house" without changing anything up high.

What it concedes: it's the hardest of the three to learn, because it requires everyone to agree on where the line is and to switch mode at the same instant. Two players on different sides of "are they below the dots yet?" is exactly the kind of disagreement that produces a goal against.

There are inverted versions — some teams play man on the puck carrier anywhere and zone away from the puck, which is arguably the true modern default. If your coach says "man on the puck, zone off the puck", that's this family.

Box+1 and the Collapsing Box

Box+1

Convention: Four players form a box around the slot — two low near the posts, two higher near the tops of the circles
Convention: The "+1" is the only player who chases the puck; when the puck moves, the role passes to whoever is nearest and the box rotates one position to fill the space
Convention: Coaching material has it the standard introductory structure for young players and beginner adults — passive, forgiving of mistakes, and a simple picture of where to stand; nobody publishes a count of what teams run
Key: Not a penalty-kill box — that is four players, two high and two low; Box+1 is a five-player even-strength shape
Countered by: A good puck-moving team — one chaser cannot pressure them, so they hold the puck and pick their moment

Four players form a box around the slot — two low near the posts, two higher near the tops of the circles — and the fifth player, the "+1", is the only one who chases the puck. When the puck moves, the +1 role passes to whoever is now nearest, and the box rotates one position to fill the space they left.

Box+1, one of several defensive-zone systems: coaching material calls it the standard introductory structure for young players and beginner adults, and nobody publishes a count of what teams actually run. It is not a penalty-kill box — that is four players, and this is a five-player even-strength shape. The box’s depth is fixed, its width is not, so read the width drawn here as one reasonable version, not a measurement.

What the shapes and fills mean

Where it actually gets used:

As a teaching system. Coaching material describes it as the standard introductory defensive-zone structure for young players and beginner adults, because it is passive, forgiving of individual mistakes, and gives everyone a simple picture of where to stand. Coaching resources present it explicitly as the stepping stone to sagging zone or hybrid coverage later. Nobody publishes a count of what teams actually run, at any level, so take both of those as coaching consensus rather than a measured fact.
In rec and beer league, where nobody has practised rotations and the priority is that five people are not all chasing the same puck.
It is not a penalty-kill box. A penalty-kill box is four players with two high and two low (see Special Teams). Box+1 is a five-player even-strength shape. Same word, different thing.

What it concedes: almost everything on the perimeter. One chaser cannot pressure a good puck-moving team, so they will hold the puck as long as they like and pick their moment. It buys structure at the cost of ever getting the puck back.

The collapsing box (and the strong-side overload)

Convention: The collapsing box is a state, not a full system — the box shrinks toward the crease as the puck goes below the goal line, all five inside the house with sticks in lanes
Read: Use it protecting a lead late, defending 6-on-5 with their goalie pulled, when structure has already gone, or against a team dangerous below the circles but not from its defencemen
Risk: You concede the entire outside by design
Options: The strong-side overload is the opposite adjustment — all five shift to the puck side, cutting the ice in half and squeezing the carrier
Countered by: One hard, accurate cross-ice pass — the overload leaves the whole weak side unoccupied by design

The collapsing box is a state rather than a full system: the box shrinks toward the crease as the puck goes below the goal line or into the corner, so all five of you are inside the house, sticks in lanes, conceding the entire outside. It's what low zone collapse turns into under maximum pressure.

The collapsing box — a state rather than a full system: as the puck goes below the goal line it shrinks until all five defenders are inside the house, sticks in the passing lanes. It concedes the entire outside by design, the points included, and leaves no breakout speed the moment you win the puck. Teams use it in spots — protecting a lead late, six-on-five against a pulled goalie — not to defend a whole game.

What the shapes and fills mean

Where it gets used:

Protecting a lead late, when a shot from the point costs you nothing and a seam pass costs you the game. See Game Management.
Defending 6-on-5 with the opposing goalie pulled.
When you are outnumbered or scrambled and structure has already gone (see When the System Breaks).
Against a team that generates nothing from its defencemen but is dangerous below the circles.

The strong-side overload is the opposite adjustment: instead of collapsing toward the net, all five players shift to the puck side, cutting the ice in half and squeezing the carrier for time and space. It is aggressive, generates turnovers, and dies to one hard accurate cross-ice pass — the whole weak side is unoccupied by design. Some teams use it as their base system; others use it as a situational squeeze when they need the puck back. Nobody publishes a count of which use is commoner.

The strong-side overload: all five defenders on the puck side, and the weak side unoccupied by design. The dashed route is the counter — the cross-ice pass to the attacker alone at the far post. Some teams use it as their base system, others as a situational squeeze; nobody publishes a count of what teams actually run, so neither is offered here as the commoner one. A coaching choice: find out whether yours plays it, and when.

Comparison Table

	Low zone collapse (zone)	Man-on-man	Hybrid (man low / zone high)	Box+1	Collapsing box
Who takes the corner	Strong-side D, plus the centre as second body	Whoever's assigned check went there — often a winger	Strong-side D and the low forward, locked on their men	The "+1" chaser only	Nobody. You concede the corner entirely
Who has the net front	Weak-side D	Whoever's check is standing there	Whichever of the low three is matched to the net-front forward	The two low players in the box	Both D, plus whoever else is inside
Who covers the points	Both wingers, high, one per side	The two wingers, man-marking the opposing D	Both wingers by area — until their man walks down	Nobody, properly. The two high box players sit at the tops of the circles, roughly 29 feet below the blue line, and close only when the puck arrives there	Nobody. Point shots are the accepted cost
Opposing D walks down from the point	The known weakness. Winger follows a few feet but doesn't chase; can become a free walk-in	Winger goes with them all the way, including into the corner	Winger tracks them man-on-man as soon as they cross the dots — this is the fix	Box holds; the +1 or nearest high player picks them up late	Absorbed into the box; they get a clean shot from the top of the circle (about 35 feet)

What it concedes	Point shots, the walk-down, extended possession, and the seam between areas	Picks, mismatches, exhaustion, and total collapse if one player loses their man	Confusion at the man/zone boundary; demands constant communication	The entire perimeter; you rarely get the puck back	Everything outside the house, and any breakout speed
Breakout readiness when you win it	Good — two wingers already high	Poor — you're standing wherever they put you	Good	Moderate	Poor — all five are below the circles

The short version, for anyone who cannot see that table.

How hard each is to learn. Box+1 is the easiest, and low zone collapse is close behind it. Man-on-man is the easiest to understand and among the hardest to execute. The hybrid is the hardest of all: everybody has to agree where the line between man and zone coverage sits — the dots, the hash marks or the tops of the circles — and switch mode at the same instant.
Who covers the points. The collapse and the hybrid put a winger on each one, and man-on-man marks the opposing defencemen wherever they go. Box+1 and the collapsing box do not cover the points properly at all. In Box+1 the two high players sit at the tops of the circles, roughly 29 feet below the blue line, and close only once the puck is already there, so a defenceman walking down is picked up late if at all. In the collapsing box, point shots are the accepted cost.
What shape you are in when you win the puck. Good in the collapse and the hybrid, because both wingers are already high and are two immediate outlets. Moderate in Box+1. Poor in man-on-man, where your five are standing wherever their five chose to stand, and poor in the collapsing box, where all five of you are below the circles with a long way to skate.

How to Tell Which System Your Team Plays

Ask the coach. That is genuinely the first answer, and one specific question gets you most of the way: "When the puck is in our corner, does the winger stay on the point or go help?" The answer separates zone from man immediately.

If you can't ask, watch one shift with a defensive-zone faceoff and look for these tells:

Watch the weak-side winger when the puck goes into the corner. Do they stay at the blue line and then sag into the high slot? That's low zone collapse. Do they leave with the opposing defenceman? That's man or hybrid.
Watch what happens when an opposing defenceman walks down from the point. Nobody follows past a few feet — zone. Somebody tracks them all the way — man or hybrid.
Count your players below the tops of the circles when the puck is behind your net — but count the wingers, not the heads. Both a collapse and a hybrid put three low (two D and the centre), so a raw headcount tells you nothing. What separates them is where the two wingers are and why. In a collapse both wingers start on the points and only the weak-side one drops, into the high slot, and only while the centre is low — and it climbs straight back. In man or hybrid a winger leaves the point because a body left the point, and goes as far as that body goes, including into the corner. Five low is neither: that is a collapsing box, which is a situational state rather than a system.
Listen to the talk. "I've got the net", "you take the corner", "shift over" is zone language. Names and "they're yours", "switch", "stay with them" is man language.
Watch the second defenceman. If they never leave the goalmouth regardless of who is standing there, you're in a zone. If they follow a specific body out to the half-wall, you're in man.

Most defensive-zone breakdowns are not effort problems — coaching consensus, not a counted figure

Convention: Almost always both players worked hard, on different assumptions about who had whom, and skated hard in the wrong directions — coaching consensus rather than a measured fact, because public tracking counts the play the offence made and not the breakdown that let it in
Mindset: Knowing your system is a skill, not admin — a player who knows the structure and skates at 80% out-defends one who doesn't and skates at 100%
Action: Announce your intentions, not your observations — "I'm going to the corner, you've got my slot" resolves the ambiguity instead of describing it
Priority: When in doubt, default to the house — get inside, stick in a lane, cover the most dangerous unmarked player

When a goal goes in from the slot, the instinct on the bench is to say someone didn't work hard enough. Almost always, both players worked hard. What happened is that two players were operating on different assumptions about who had whom — the centre thought the weak-side winger was collapsing, the winger thought the centre was staying high; the defenceman thought their partner had the net, the partner thought the puck battle needed two. Both skated hard, in the wrong direction, at the same time. (Coaching consensus rather than a measured fact: public tracking counts the play the offence made, not the breakdown that let them in.)

Three consequences follow:

Knowing your system is a skill, not admin. A player who knows the structure and skates at 80% will out-defend a player who doesn't and skates at 100%.
Announce your intentions, not your observations. "They're coming down your side" is useful. "I'm going to the corner, you've got my slot" is far better, because it resolves the ambiguity rather than describing it.
When in doubt, default to the house. If you genuinely don't know whether someone is yours, get inside, get your stick in a lane, and cover the most dangerous unmarked player. You will almost never be badly wrong.

Defending Specific Threats

Systems tell you where to stand. These are the recurring plays you'll actually face, and what to do about each.

The cycle

In short: Don't chase it round the boards: defend the next pass and the exit points, and send two to win one battle.

Key: Attackers rotate the puck between the corner, the half-wall and behind the net, passing into the space they just left, until somebody chases out of position
Never: Chase the puck around the boards. Let it come to you instead and defend the exit points, not the puck's current location
Read: Take away the next pass, not the current one — the man arriving is the threat
Position: Cut it at the goal line — meet a carrier coming out from below the goal line at the post, not in the corner
Convention: Under a collapse, be patient — the house is full and they aren't threatening you; under man or hybrid, stay on bodies, goal side — never hold or hook them, puck or no puck, nor bump one without it, or at all where checking is barred
Action: Get one hard win — cycles end when somebody wins a puck battle, so send two, which in the collapse is the strong-side defenceman and the centre
Never: Send the second body into a back — the player digging along your boards cannot see you, and no book prices a hit to the back that stays off the head at two minutes alone
Rule: Pull up on a back — the NHL, PWHL and IIHF write no minor for a hit from behind (43.2); the NHL and PWHL give a major and game misconduct (43.3, 43.5), under the IIHF plan on it (43.3); on the head, the harsher of Rules 43 and 48
Rule: At a club in England or Wales, outside the Elite League, a game misconduct for checking from behind or a head check, or a boarding major, is at least a one-game ban (IHUK DOPS C.1)
Rule: Hockey Canada 7.5: minor and game misconduct, major and game misconduct on violence, mandatory on injury, match "into the boards or goal frame" if defenceless; on the head, head contact (7.6; 7.7), up to a match; head first into boards or goal, the harsher of 7.5 and head contact
Rule: CARHA 53(a) puts a game misconduct on every hit from behind, minor or major, the major mandatory on injury, and 53(b) makes one into the boards or goal net on a player unable to protect themselves a mandatory match (CARHA adult leagues only)
Rule: USA Hockey alone lets you play on at its floor (608(a)'s minor plus misconduct) — but its Casebook (608 Sit. 1) requires a major and game misconduct or a match "⁠[i]n every instance where a player forcefully checks an opponent who is standing along the boards"; a match: likely multi-game ban
Rule: USA Hockey 608(c) is a mandatory match — "shall be assessed" — for a check from behind that recklessly endangers an opponent "with excessive force while the opponent is in a vulnerable or defenseless position"; for any reckless check from behind, plan on a match and a likely multi-game ban (602(a))
Rule: A USA Hockey misconduct is ten minutes only by default — 404(a) writes "10 minutes, or the designated misconduct penalty time", and its Note lets non-Adult affiliates set 6:00 for periods of 12 minutes or less, 8:00 under 17. NHL, IIHF, PWHL, Hockey Canada and CARHA write a flat ten

What it is: attackers rotate the puck between the corner, the half-wall and behind the net, passing to a teammate who is arriving into the space they just left. It's a possession tactic designed to make you chase until someone is out of position.

Defending it:

Don't chase the puck around the boards. The cycle wins when your five players are strung out following it. Let it come to you and defend the exit points, not the puck's current location.
Take away the next pass, not the current one. The cycle is a sequence; the man arriving is the threat.
Cut it at the goal line. The most valuable place to break a cycle is stopping a carrier who is trying to come out from below the goal line to the front of the net. Meet them at the post, not in the corner.
Under a collapse, be patient. The house is full and they aren't threatening you. Time is on your side; they'll eventually force something.
Under man or hybrid, stay on bodies. The cycle is specifically designed to beat area coverage, and man coverage low is the strongest answer to it. Staying on a body means goal side of them and within a stick length — never holding or hooking them, puck or no puck, and no bump while they are without it — or at all where checking is barred. Each draws a penalty wherever you play.
Get one hard win. Cycles end when somebody wins a puck battle. Two of you on one carrier — strong-side defenceman and centre in the collapse system — is how you get that. ⚠️ The second body arrives late and unseen, so arrive on the puck or on the ice they want, never on their back. A cycling forward on your boards is digging the puck out with their head down.

What it costs. ⚠️ Arrive on the puck, never on a back: no book here prices a hit to the back that stays off the head at two minutes, and in most it ends your game. Hockey Canada and CARHA make one into the boards or goal frame on a player unable to protect themselves a match (7.5(c), 53(b)). USA Hockey's softer floor does not reach this play: its Casebook requires a major plus a game misconduct, or the match penalty, "⁠[i]n every instance where a player forcefully checks an opponent who is standing along the boards (back toward the middle of the ice)" (Rule 608, Situation 1) — the cycling forward exactly — and for a reckless one, plan on a match and a likely multi-game suspension (602(a)). Under Hockey Canada, once it reaches the head it is head contact (7.6; 7.7), up to a match; driven head first into the boards or goal, the harsher of 7.5 and head contact. Body Contact and Battles → Checking from behind has every tier.

The low-to-high play

In short: When the puck goes low, wingers close on their points early and everyone else boxes out the bodies in front.

Key: The puck goes low to drag your coverage down, then back up to the point or the high slot for a shot with your backs turned and traffic in front — it exists to punish low zone collapse
Never: Get sucked low as the strong-side winger. Stay high instead, in the lane, between that defenceman and the net
Read: When the puck goes behind the net, expect the low-to-high next — close on your point as it disappears, not when it comes out
Action: Get out to the shot, don't sit under it — a winger at the hash marks blocks nothing; one closing hard at the top of the circle, head up and out of the shot lane, does
Never: Lunge at the shot, lift a leg, turn sideways or turn your back on it — close with your feet, square, shin pads to the puck, and stay on your feet until it is released
Action: As the puck goes high, the low players watch it and box out the man — hold the inside, no lean, no push, under CARHA no body contact; never walk them off it — that can be called interference anywhere

What it is: the puck goes down to the corner or behind the net, drags your coverage low, and then gets passed back up to the point or the high slot for a shot with your defenders' backs turned and traffic in front. Coaching material routinely calls it one of the most common ways modern teams score, and it exists precisely to punish low zone collapse. (Public tracking splits five-on-five offence into rush and forecheck-and-cycle, and does not break out the low-to-high on its own — Neutral Zone Systems covers what it counts — so "one of the most common" is coaching consensus rather than a measured figure. Shot location is public and plentiful; Shooting covers it.)

Defending it:

The strong-side winger's discipline is the whole answer. They stay high, in the lane, between that defenceman and the net. If they got sucked low, the low-to-high is free.
Recognise the trigger. When the puck goes behind the net, expect the low-to-high next. Wingers should already be closing on their points as the puck disappears behind the goal line, not reacting when it comes out.
Get out to the shot, don't sit under it. Close the distance to the shooter. A winger standing at the hash marks isn't blocking anything; a winger closing hard at the top of the circle, head up and out of the shot lane, is. Close with your feet rather than lunging, square with your shin pads to the puck, hands behind your body with the backs of the gloves out, stick down beside you — never lift a leg, turn sideways or turn your back on it — and stay on your feet until it is released.
Everyone else boxes out — eyes on the puck, body beside the man. The shot is only dangerous because of the tip and the rebound, and you cannot beat anyone to a rebound you did not see leave the stick. As the puck goes high, get to the inside of the player in front of you and hold that spot — no lean, no push, and in a CARHA game hold it without putting a body on them at all. Never walk someone off a spot they already hold — that can be called interference wherever you play.

What it costs. If your game bars checking, the walk-off is an illegal check as well (Dealing with the screen has the citations). Even in a checking game, NHL and IIHF 56.1 and PWHL 57.1 bar moving laterally into a player without established position, and USA Hockey 625(a)(4) bars changing your lane or foot speed to play the body of an opponent no longer in control of the puck. Under the IIHF's women's rule, 101.1, the inside position is yours only if you reached it first: a player already standing there is entitled to that ice, and stepping or gliding into her is at least a minor.

The point shot with a screen

What it is: they shoot from the blue line with a forward parked in front of your goalie. The shot doesn't need to be good; the goalie can't see it, and the rebound comes off a moving body.

Defending it: two jobs, and different rules govern each.

Dealing with the screen

Key: Screening from outside the crease, without contact, is normally legal — the referee will not help you in real time
Action: Deal with the screen, don't watch it. Get your body between them and your goalie's sightline
Technique: Never walk a screener out — it can be called interference wherever you play, and where checking is barred an illegal check too. Take the position and hold it, no lean, no push
Rule: A checking game does not make the net-front walk-out legal — a body check is delivered on a puck carrier and the screener is not one, so interference governs: NHL and IIHF 56.1 and 56.2(i), PWHL 57.1 and 57.2(i) — at least a minor for impeding a player "not in possession of the puck"
Rule: USA Hockey 625(a)(4) names the walk-out, a minor for changing "skating lane or foot speed in an effort to play the body" of a player without the puck, in checking games too; a check can be roughing (640); if reckless, major and game misconduct — plan on a match and a likely multi-game ban (602(a))
Rule: Walking an opponent off an established position is a push, and USA Hockey does not cap it at a minor where checking is barred — 604(c) a minor; if the push recklessly endangers them, 604(d) a major plus a game misconduct, and plan on a match and a likely multi-game ban (602(a), 604(e))
Rule: Hockey Canada prices the push that walks a screener off their position at U13 and below, in female hockey and in any division a Member has approved — 7.3(a) a minor, 7.3(b) a major plus a game misconduct on the degree of violence with nobody hurt, mandatory on injury, 7.3(c) a match penalty
Rule: Under the IIHF's women's rule it is an illegal hit (101.1) — "⁠[a]ny move by a Player to step or glide into an opposing Player" is at least a minor, with a major and an automatic game misconduct above it. Hold only ice you reached first
Rule: CARHA lets a defender "stand their ground" (66(a) Note 2), but 49(a) prices pushing, shoving or failing to "avert body contact" at a minor or major, mandatory if intentional contact injures, and a major ejects with at least a one-game ban (30(a), 32(d)). Hold the spot; never lean, push or step in
Rule: USA Hockey's Competitive Contact list is a floor, not a ceiling — 604(a) lets a local governing body prohibit body checking in any classification, and 604(b) prohibits it whenever a Competitive Contact team plays a Body Checking team. Check the game, not the age group

Deal with the screen, don't watch it. Screening from outside the crease, without contact, is normally legal, and the referee will not help you in real time. Get your body between the screen and your goalie's sightline. ⚠️ Do not walk them out — that can be called interference wherever you play, and where checking is barred an illegal check as well.

Stop at the box-out and the stick lift. Holding a position you already have is legal in most books; driving someone off theirs is not. In a Hockey Canada game, hold only ice you already have — a box-out that stops a forward getting where they are going can be called. Under CARHA, hold the spot with no lean and no push, never step into their path to take the contact, and avoid any contact you can. ⚠️ Under IIHF women's rules, the ice you hold is ice you reached first — a player already standing there has it, and you go around her. Some women's leagues go further: Britain's WNIHL sets its senior and U16 games as "Full ice, non-checking".

Check the game, not the age group. Under USA Hockey a checking-age team can be in a no-checking game for the night purely because of who it drew, and a league can take checking out of a classification the list says permits it. Body Contact and Battles → 1. Which Contact Rules Are You Actually Playing Under? sets out which rules are yours.

What it costs.

Interference, wherever you play. A body check is delivered on a player in control of the puck, and the screener is not one, so what reaches you is interference. NHL and IIHF 56.2(i) and PWHL 57.2(i) make it a minor for a player who "interferes with or impedes the progress of an opponent who is not in possession of the puck". USA Hockey 625(a)(4) names this play: "⁠[a] defending player who changes their skating lane or foot speed in an effort to play the body of an opponent who is no longer in control of the puck." Rule 625 has no Competitive Contact scope, so it reaches you even where checking is legal.
Above the minor. ⚠️ Only USA Hockey's interference rule stops at a minor. The NHL (56.4) and PWHL (57.4) allow a major on the violence, with the game misconduct compulsory once it is for an injury (56.5, 57.5). The IIHF allows a major, or a major and game misconduct, where it recklessly endangers (56.4, 56.5). Hockey Canada allows a major and game misconduct with nobody hurt, compulsory if they are injured (8.3(b)). CARHA allows a major and game misconduct (66(a)), a major compulsory on injury (66(e)), and a CARHA major ejects you and costs at least the next game (30(a), 32(d)). A push meant to injure the screener is a match penalty in every book here but the IIHF, which tops out at a major and game misconduct (56.5) — NHL and PWHL 21.1, Hockey Canada 8.3(c), CARHA 48(a), USA Hockey 602(a), with a likely multi-game suspension there.
USA Hockey, beyond interference. A walk-out that becomes a body check can be roughing under 640, where 640(g) is a major plus a game misconduct for reckless endangerment, with a match and a likely multi-game suspension to plan on (602(a)). Done two-handed with the arms extended it is a cross-check under 609, with the same major and the same match; the Casebook draws that line at the net front itself (Rule 609, Situation 2).
Where checking is barred, under USA Hockey. Driving an opponent off their spot is a minor under 604(c) in every Competitive Contact classification — 12U and below, all girls'/women's, all non-check adult — because 604's Note 1 counts "physically forcing the opponent off the puck and with no effort to legally play the puck". ⚠️ That minor is not the ceiling, and at the net front it matters most, because the player is stationary with your goalie and the post behind them. 604(d): "A major plus a game misconduct penalty shall be assessed to any player who recklessly endangers an opponent with a body check in a Competitive Contact category". 604(e) adds that a match "may also be assessed". Plan on one anyway, and a likely multi-game suspension, because 602(a) says a match "shall be assessed" to any player who "recklessly endangers or attempts to injure" an opponent.
Where checking is barred, under Hockey Canada. 7.3(a) is a minor for a player who "intentionally body-checks, bumps, shoves, or pushes any opposing player", and it applies "only in divisions of U13 and below, in female hockey, and any other divisions approved by a Member of Hockey Canada". ⚠️ 7.3(b) allows a major and game misconduct on the violence with nobody hurt, and makes that pair mandatory — "If a player is injured, as the result of a body-checking infraction that would otherwise call for a Minor penalty, a Major penalty and Game Misconduct penalty must be assessed." A screener shoved into your own goalie or the post is how that arrives. 7.3(c) is a match for deliberately injuring or attempting to.
USA Hockey's list is a floor. 604(a) adds that "A local governing body may prohibit body checking in any classification", and 604(b) that "⁠[a]ny time a team from a Competitive Contact category… plays a team from a Body Checking category, body checking shall be prohibited under this rule."
What the books say about holding position. The NHL at 56.1 — "⁠[a] player is allowed the ice he is standing on (body position) and is not required to move in order to let an opponent proceed" — and the IIHF (56.1) and PWHL (57.1) say the same with "they" and "she". USA Hockey's Declaration of Player Safety says a skater "is entitled to stand their ground". The Note to 604(c) is narrower: it covers players "focused on gaining possession of the puck" and "simply maintaining established body position", and protects them only "under this rule". So it is no answer to the interference rule, whose Note leaves alone a player who maintains "an established skating lane". Hockey Canada writes no equivalent — its only mention of body position, 8.1, assumes it rather than granting it — and its 8.3 calls impeding "the progress of an opponent, who is not in possession of the puck" interference.
CARHA. Note 2 to 66(a) says "the defending players are entitled to 'stand their ground'". But 49(a) penalises a player who "intentionally bodies, pushes, shoves" or "does not avert body contact with an opponent": a minor or a major, the major mandatory "⁠[w]hen injury results from intentional body contact", and a CARHA major ejects you and costs at least the next game (30(a), 32(d)).
IIHF women's hockey. Rule 101.1 allows contact only for the puck: "'bodychecking' is allowed when there is a clear intention of playing the puck", and two players chasing it may push and lean "provided that 'possession of the puck' remains the sole object". Moving a screener is not playing the puck. A stationary player "is entitled to that area of the ice", and "⁠[i]t is up to the opponent to avoid body contact with such a Player". And "⁠[a]ny move by a Player to step or glide into an opposing Player will be assessed at least a minor penalty (2') for an 'illegal hit'", with a major (5') plus an automatic game misconduct above it. The WNIHL is non-checking at U16 and senior level.

Lifting the screener's stick

Technique: Lift the stick up, not sideways, low on the shaft, well below the bottom hand, as the puck arrives, then let go — never on into their head. A screen with a free stick is a deflection waiting to happen
Rule: IIHF 55.1 is the flattest — a stick at or near the hands is hooking, though its next sentence exempts stick-to-stick contact and the book does not reconcile them. Low is still the answer. USA Hockey 623 and Hockey Canada's Interpretation 1 to 8.2(a) reach a lift only where it stops a pass or shot
Rule: A chop at the hands is slashing in all six books — NHL 61.1, IIHF 61.1 and PWHL 63.1 in the same words bar the pronoun, USA Hockey 634, Hockey Canada 9.3, CARHA 80. A clean lift for the puck is not a chop and sits outside all six, but USA Hockey's note writes no attempt-to-play-the-puck let-out
Rule: A chop reaches a major plus a game misconduct with nobody injured in all six books — NHL 61.3 and 61.5, IIHF 61.3, USA Hockey 634(b), Hockey Canada 9.3(b), PWHL 63.3 and 63.5, CARHA 80(a) with 30(a)'s game misconduct. A hooking major needs an injury everywhere but IIHF 55.3 and USA Hockey 623(b)
Rule: Hockey Canada 9.5's list names no division of its own: an accidental lift injuring the head or neck is a double minor, a "pitchfork action in lifting the stick" doing the same a major and game misconduct; in minor and female hockey 7.6 governs: "no type of legal contact to the head, face, or neck"
Rule: Never trade the lift for a cross-check — above the shoulders it is a major and game misconduct with nobody hurt under Hockey Canada (7.6(b); 7.7(b)) and CARHA (54(b)); in minor and female hockey a lift reaching the head gets there on violence, and must on injury (7.6(b))

Lift the stick as the puck arrives — up rather than sideways, low on the shaft, well below the bottom hand — then let go. ⚠️ Lift under the shaft, not through it, and stop at their stick — the stick you lift ends near their face. Low is the answer: below the bottom hand the lift stays off their hands, still takes the stick off the ice, and keeps your blade further from their head.

Never chop at the hands instead — a chop is slashing in all six books, and it only moves you up the ladder. And never trade the lift for a cross-check: under Hockey Canada and CARHA a cross-check above the shoulders is a major and game misconduct on contact alone. Under Hockey Canada the lift gets there only on high violence or an injury, and CARHA makes any stick to the head a major (62(b)). A screen with a free stick is a deflection waiting to happen; a screen with a lifted stick is just a person, and this is the highest-value thing a net-front defender does. Body Contact and Battles → The stick lift carries the full comparison.

What it costs.

A lift at the hands. Three of the six books call it hooking. IIHF 55.1 does so on the location alone: "⁠[i]f the stick goes against the opponent's hands / or near the opponent's hands, it shall be penalized as 'hooking'". USA Hockey 623 and Hockey Canada's Interpretation 1 to 8.2(a) do so only where it stops them passing or shooting. The IIHF's next sentence exempts "only stick-to-stick contact", and no IIHF interpretation reconciling the two is held here; reading the hands sentence as operative is the cautious choice, and may be stricter than the rule. The NHL, PWHL and CARHA leave a clean lift alone. A hooking major needs an injury under the NHL (55.3), Hockey Canada (8.2(b)), the PWHL (56.3) and CARHA (64(b)), but not under the IIHF (55.3) or USA Hockey (623(b)).
A chop at the hands. NHL 61.1 makes a "forceful or powerful chop" on or near the hands that "is not an attempt to play the puck" slashing. A chop is slashing in all six books (IIHF 61.1, PWHL 63.1, USA Hockey 634, Hockey Canada 9.3, CARHA 80), and in every one it reaches a major plus a game misconduct with nobody injured. ⚠️ In CARHA and USA Hockey that major costs the next game as well: CARHA puts a game misconduct on every major except an accidental high stick that injures nobody (30(a), 62(b)) and at least a one-game suspension on any but an accidental high stick (32(d)). The NHL and PWHL suspend on a second stick-foul game misconduct (23.5), Hockey Canada on one taken in the last ten minutes or overtime (4.8(c)).
A lift that reaches the head, Junior and Senior. Hockey Canada writes two escalations, both triggered by injury, in the interpretations under Rule 9.5. An "attempted lifting of the opponent's stick, which results in accidental contact to the head or neck area" that "causes injury" is a double Minor. A "pitchfork action in lifting the stick" that "results in contact to the neck or head area, causing injury" is a Major penalty and Game Misconduct. That list states no division of its own; Junior/Senior is inferred from Rule 9.5, High-Sticking – Junior/Senior, which it sits inside.
A lift that reaches the head, minor and female hockey. ⚠️ Rule 7.6 governs, and it is no relief: "There is no type of legal contact to the head, face, or neck". Even accidental head contact is a minor (7.6(a)), three in one game is an ejection (4.8(b)(ii)), a major and game misconduct is discretionary with nobody hurt and mandatory if they are injured (7.6(b)), and 7.6(c) is a match if they cannot protect themselves or you tried to injure them.
The high cross-check, every Hockey Canada division. ⚠️ It is a major and game misconduct on contact alone: "Any player who strikes an opponent above the normal height of their shoulders with a cross-check will be penalized with a Major penalty and a Game Misconduct penalty, whether or not injury results". That is 7.6(b), printed word for word in Junior/Senior's 7.7(b), and CARHA 54(b) is the same. Three stick-infraction minors in one game, cross-checking and high-sticking among them, also end your night (4.8(b)(i)).

When the shot is already away

Never: Block a shot from a screening position — you change the direction of a puck your goalie never saw
Technique: Block from close if you block at all — ten feet from the shooter, square, shin pads to the puck, head up and out of the shot lane, hands behind you, backs of the gloves out, stick down beside you
Never: Lift a leg, turn your back or go sideways, or lunge. Close with your feet instead, and stay on your feet until the puck is actually released
Action: Talk to your goalie — "screen left", "I've got the tip"; they are trying to find the puck through legs

What it is: the screen is still standing, the shot is on its way, and your goalie has not seen it leave. Winning the position back is no longer one of your options.

Defending it:

Don't block the shot from a screening position. Half-blocking a shot your goalie cannot see is worse than not blocking it, because you've changed the direction of an already invisible puck. If you're in the sightline, get out of it or take the inside on your man without pushing them; let the puck through.
Block from close if you block at all. Ten feet from the shooter, square, shin pads to the puck, head up and out of the shot lane, hands behind your body with the backs of the gloves out, stick down beside you. Never lift a leg, never turn your back or go sideways, and never lunge — close with your feet, and stay on your feet until the puck is actually released. See Body Contact and Battles for the rest of what to protect, and for when not to block at all.
Talk to your goalie. "Screen left", "I've got the tip" — they are trying to find the puck through legs.

The back door / weak-side seam

Key: While everyone watches the strong-side battle, an attacker drifts to the far post — one cross-ice pass and it is an open net
Priority: The chance every coverage system is most afraid of, and worth conceding almost anything else to prevent
Never: Lose the man at the back post while you watch the puck — as the weak-side defenceman your eyes track the puck and your body stays between them and the net
Technique: Lie your stick flat in the seam across the slot — it makes the play impossible even when the passer is open
Convention: Weak-side winger sags into the middle rather than standing pretty at the point — a body in the high slot is worth more than perfect point coverage
Action: Call the arrival, not the goal. "Back door!" the moment they appear, not when the pass is on the way

What it is: while everyone watches the strong-side battle, an attacker drifts to the far post. One cross-ice pass and it's an open net. This is the chance every coverage system is most afraid of, and the one worth conceding almost anything else to prevent.

Defending it:

The weak-side defenceman never watches the puck. Your eyes track the puck, your body stays between the man at the back post and the net — position, never a hold or a push, either of which can draw a penalty. If you find yourself facing the corner, you've already lost them.
Stick in the seam. The pass has to cross the slot. A stick lying flat in that lane makes the play impossible even when the passer is open.
Weak-side winger sags into the middle rather than standing pretty at the point. The seam runs through the high slot; a body there is worth more than perfect point coverage.
Call the arrival, not the goal. "Back door!" the moment they appear, not when the pass is on the way.

The walk-down from the point

Key: Instead of shooting, the opposing defenceman skates down toward the top of the circle — in a pure zone they cross out of the winger's area and into nobody's
Action: Find out your team's version before you need it — this one is a coaching choice, not a rule of hockey
Convention: Under low zone collapse, follow a few feet, stay connected and call the switch loudly, but do not chase into the corner
Convention: Under man-on-man, you go with them all the way, wherever they go
Convention: Under hybrid, release from zone and pick them up man-on-man as soon as they cross the dots
Priority: When a fourth attacker arrives low, somebody gives up their area and it must not be the goalmouth — usually the centre absorbs them and the weak-side winger takes the high slot

What it is: instead of shooting, the opposing defenceman skates down from the blue line toward the top of the circle — about 35 feet from the goal line — or all the way to the hash marks. In a pure zone system, they cross out of the winger's area and into nobody's, and get a clean look from there or an easy feed into the slot.

The walk-down from the point, answered by low zone collapse: the winger follows a few feet and does not chase, so their route ends in a stop, not an arrowhead. The opposing defenceman reaches the top of the circle, about 35 feet from the goal line, untouched. A coaching choice — man-on-man and hybrid teams answer it differently, so find out your team’s version before you need it.

What the shapes and fills mean

The walk-down from the point under man-on-man: the winger goes with the carrier, wherever the carrier goes, including into the corner — the sharpest practical difference from low zone collapse. Everybody else is on a body too. A hybrid produces nearly this picture, and the difference is only the trigger, usually the faceoff dots, though some teams draw it at the hash marks or the top of the circles, so learn your team’s. What man coverage costs is a winger in a footrace with no help behind them.

What the shapes and fills mean

Defending it — and this is a coaching choice, so know your team's version:

Under low zone collapse: the standard instruction is that the winger follows them down a few feet and stays connected, but does not chase into the corner, and calls the switch loudly so the centre and defencemen know a fourth attacker is arriving low. This is a genuine compromise, and it is the system's weak point.
Under man-on-man: you go with them, all the way, wherever they go. Simple, and the reason the walk-down doesn't trouble man teams.
Under hybrid: you release from zone and pick them up man-on-man as soon as they cross the dots. This is the cleanest answer of the three, and the main reason hybrids exist.
Everyone else: when a fourth attacker arrives low, you are outnumbered down there. Somebody has to give up their area and it must not be the goalmouth. Usually the centre absorbs the extra man and the weak-side winger takes over the high slot entirely.

Pinned in your own end on a long shift

What it is: forty seconds and more in your own end, legs going, and the other team working the puck around the wall. This is when the shape breaks, because tired players start chasing.

Defending it:

Shrink, don't chase. Hold your area or your man, keep your stick in the lane and let them work the wall. Chasing costs the most energy and opens the most ice, and under the collapse the house stays full while they cycle.
Take the first clean chance to get it out, and get it out where it stays out. Off the glass and out, or chipped into the neutral zone — not fired the length of the ice. An icing brings the faceoff straight back to your end. Under the NHL, IIHF and PWHL books, and Hockey Canada's in U18AAA, Junior and (where the Member opts in) Senior, your tired line cannot change for it, though an injured player can still be replaced. Clearing the Zone sets out which books do what.
Change only once the puck is out and heading the other way. A change with the puck still loose in your end is one of the commonest ways a team hands the other an odd-man rush. The common approach is that whoever is nearest the bench goes first as the puck leaves; some coaches want it dumped deep before anyone moves, so ask your bench which yours wants.
Say it. "Out — change!" as the puck leaves tells your linemates and the bench at the same moment.

The net-front scramble

In short: Take the most dangerous stick first, stay on your feet, and move the puck with your stick, never a closed hand.

Priority: Body first, puck second — as the puck arrives, lift the most dangerous stick low on the shaft, well below the bottom hand, or press its blade down; stop at their stick, then let go
Never: Grab their stick, or keep a pin on it after the shot — a grab is at least a holding minor in every book, in CARHA possibly a major that ejects and bans you, and a pin you keep can be called holding
Rule: Holding an opponent's stick so that it injures them is a major plus a game misconduct under Hockey Canada 8.1(b), and a major under CARHA 63(b) that ejects you and costs at least your next game (30(a), 32(d))
Never: Lunge at the puck through your goalie — you will knock the puck loose or knock them off their post
Rule: Your stick is legal for moving a loose puck — jab it out low rather than swinging, which NHL 60.1 strips of the accidental-contact defence and 60.3 makes at least a double minor where it injures; freezing it under the blade to force a whistle is its own minor (63.2(i))
Never: Close your hand on the puck, cover it or smother it under your chest — a minor, and a penalty shot in your crease. An open-hand knock-down is no penalty anywhere
Rule: Outside your own crease, dropping to block a shot is no penalty where the puck is shot under you or becomes lodged in your clothing or equipment — what is penalised is using your hands to make it unplayable (NHL 63.2(v) NOTE, IIHF 63.2(V), USA Hockey 614(a))
Rule: Hockey Canada prints no shot-blocker Note of its own but reaches the case further, at Interpretation 6 to 10.1(a): a body lying in the crease with the puck frozen under it is "No Penalty Shot or Minor penalty, provided that the player has made no deliberate attempt to cover the puck"
Rule: You may hand-pass in your own zone (NHL Rule 79.2), and the test is where the puck is, not where the skates are
Never: Hand-pass it out to a breaking winger — once the puck itself has left your zone the whistle goes, wherever your skates are; it is a stoppage and a faceoff, not a penalty
Technique: Stay on your feet as long as possible — a defender on the ice is out of the play for two seconds, which is the whole scramble
Risk: Going down hands-and-head-first at the goalmouth puts them under four sets of sticks swinging at the same puck. Prefer the stick — a coaching caution, not a rule
Rule: NHL and IIHF 61.1 and PWHL 63.1 punish a chop "on or near the opponent's hands" only where it is "not an attempt to play the puck" — USA Hockey 634 and CARHA 80 print no such let-out, and Hockey Canada 9.3 exempts only a tap on the puck-carrier's stick, so under those three a chop there is a slash

What it is: a rebound, a loose puck at the top of the crease, four bodies, two seconds. Coaches will tell you more goals come from here than from any highlight play. The rebound half of that is countable, and it is substantial: 11.4% of NHL goals come within three seconds of a previous shot on goal by the same team, and 19.7% within ten. Those figures are derived from the NHL's public play-by-play feed over 400 games of 2024-25 rather than published statistics (Offensive Zone Play section 10 carries the source). No public tracking breaks out the scramble as its own play, so "more than any highlight play" stays a coaching comparison.

Defending it:

Body first, puck second. Take the most dangerous stick away with your own before you look for the puck: as the puck arrives, lift it up, low on the shaft, well below the bottom hand, stop at their stick and let it go. Or press its blade to the ice as the shot comes, and let go once the shot is through. Never hook it, keep it pinned or grab it with your hand. A player with a free stick at the goalmouth will score before you get there. Whatever contact happens, keep their skates on the ice — a player lifted off their edges cannot choose what meets the post first.
Don't lunge at the puck through your goalie. You'll knock the puck loose or knock them off their post. Trust them to smother it and protect them while they do.
Whack it out with your stick — a low jab, not a swing. Your stick is legal for moving the puck; a wild swing at a bouncing puck is a high-sticking risk with no accidental-contact defence.
Your hand is a much narrower tool and your chest is not one at all. Batting a loose puck down or pushing it along the ice with your hand is no penalty anywhere. Closing your hand on it, covering it or smothering it under your body is the offence.
Blocking a shot and having the puck die under you is not the offence. ⚠️ Reaching for it with your hands to hold it there is — in your own crease, a penalty shot. The variable is deliberateness, not where you are lying.
You may hand-pass in your own zone — shoving a bouncing puck to a teammate with your hand is legal in your own end. The test is where the puck is, not where the skates are: a skate over the blue line does not matter while the puck is still in the zone, and once the puck has left it the whistle goes, wherever you stand. That is a stoppage and a faceoff, not a penalty — but don't hand-pass it out to a breaking winger.
Stay on your feet as long as possible. A defender on the ice is out of a scramble that lasts two seconds, and ⚠️ going down hands-and-head-first at the goalmouth puts your hands and head under four sets of sticks and skates. Staying up is a coaching caution rather than a rule, and it is the reason to prefer the stick.

What it costs.

The stick on a stick. Holding an opponent's stick is at least a holding minor in every book, and in CARHA possibly a major, which ejects you and costs at least the next game; if it injures, Hockey Canada 8.1(b) and CARHA 63(b) make it a major plus a game misconduct. A pin you keep can be called holding. The IIHF's interference rule, 56.1, also names stopping a player without the puck from receiving a pass, and no IIHF ruling says whether a lift as the pass arrives counts — one more reason to let go at once.
The swing. NHL 60.1, IIHF 60.1 and PWHL 61.1 remove the accidental-contact defence from "⁠[a] wild swing at a bouncing puck", and 60.3 makes it a double minor where injury results. That is not the top of it. NHL 60.4 and PWHL 61.4 make it a match where the swing was meant to hurt, and IIHF 60.4 allows a major and automatic game misconduct where it recklessly endangers. USA Hockey calls a stick to the head outside a check high-sticking: a minor that becomes a mandatory major and game misconduct where it recklessly endangers (621(a) and (b); Casebook Rule 621, Situation 1). CARHA 62(b) makes any stick above the shoulders a major, accidental or not, with a game misconduct if deliberate or anyone is hurt. Hockey Canada sends a violent one, and in minor and female hockey any that injures, to a major and game misconduct (7.6(b), 7.7(b), via 9.5(b)). USA Hockey 621(c), CARHA 62(c) and Hockey Canada 7.6(c) and 7.7(c) reach a match — and under USA Hockey plan on one, and a likely multi-game suspension, for a reckless or deliberate swing (602(a)).
Freezing it. Freezing the puck under the blade for a whistle is its own minor (63.2(i)). Batting it down by hand is free: NHL and IIHF 79.1 and PWHL 81.1 permit it with no zone limit, and USA Hockey 618(b) and Hockey Canada 10.2(a)(i) restrict the hand pass rather than the bat. Closing your hand on it is priced in the next section.
The shot-blocker's carve-out. Outside the crease, deliberately falling on the puck is a minor (NHL 63.2(v)). The rule prints the exception: "Any player who drops to his knees to block a shot should not be penalized if the puck is shot under him or becomes lodged in his clothing or equipment but any use of the hands to make the puck unplayable should be penalized promptly." IIHF 63.2(V) and USA Hockey 614(a) print the same Note. ⚠️ Hockey Canada reaches the crease version under Delay of Game: Interpretation 6 to Rule 10.1(a) has the goalie pulled, a skater lying in the crease and the puck shot under them and frozen. It rules "No Penalty Shot or Minor penalty, provided that the player has made no deliberate attempt to cover the puck." USA Hockey's Casebook rules the same (Rule 614, Situation 2): "No penalty shall be assessed" where "the puck simply ends up beneath them", but "if the player makes any action to cover the puck by gathering it into their body, the penalty shot or awarded goal situation would apply."
The hand pass. NHL 79.2: "The location of the puck when contacted by either the player making the hand pass or the player receiving the hand pass shall determine the zone it is in." Hockey Canada's 10.2(a) says in terms that "Play will be stopped but a Minor penalty will NOT be assessed for a player who commits a 'hand pass' violation", and USA Hockey 618(b) that "a stoppage of play will occur and a face-off will take place according to last play face-off rules".
A chop on your hands when you are down. Under the NHL, IIHF and PWHL little protects you. Their 61.1 (the PWHL's 63.1) penalises a chop "on or near the opponent's hands" only where it "in the judgment of the Referee, is not an attempt to play the puck", and a stick coming down on a loose puck usually is one. ⚠️ Do not carry that across to the other three books, in either direction. USA Hockey 634, Hockey Canada 9.3 and CARHA 80(a) print no such let-out (Hockey Canada's spares only a tap on the puck-carrier's stick, not a hand), so there a forceful chop that lands on a hand in a scramble is slashing whether or not it was going for the puck. It is not capped at a minor. USA Hockey 634(b) is a major plus a game misconduct for reckless endangerment, with a match and a likely multi-game suspension to plan on (602(a)). Hockey Canada 9.3(b) reaches the same pair on the violence alone, and CARHA 80(a) allows a major, which ejects you there and costs at least the next game (30(a), 32(d)). That is some protection for your hands and a real penalty risk for your own stick.

Handling a loose puck in your own crease

In short: Knock it down and play it with your stick; only your goalie may smother a puck in your crease.

Rule: The NHL and IIHF (67.2), PWHL (69.2), Hockey Canada (10.2(a)(iii)) and CARHA (61(a)) print the permission, the last two only where you gain no advantage. USA Hockey's playing rules print none; 618(a) leaves the catch-and-drop unpenalised outside the crease, and its Casebook says so in terms
Never: Hold a puck you have caught, carry it, turn with it or throw it — that is the act the books reach: a minor in five books, a USA Hockey stoppage outside the crease, the penalty shot in your own crease
Rule: What buys the penalty is what you do after the catch, not how high it was — holding it, taking a stride, turning to avoid a check, or throwing it (NHL and IIHF 67.2(I), PWHL 69.2(i); Hockey Canada Interpretation 4 to 10.2(a)(iii))
Rule: Under USA Hockey a caught puck not dropped at once outside the crease is a stoppage, not a penalty (618(a)) — but covering a loose puck with your hand there is a minor (614(a) Note; Casebook 614 Sit. 1), and in the crease the penalty shot or optional minor (614(b))
Rule: USA Hockey's minor under 618(a) is a different act — picking the puck up off the ice with the hand while play is in progress
Rule: A skater other than the goalie who covers a puck that is itself inside their own crease gives up a penalty shot — an awarded goal if your own net is empty (NHL 67.4 and 67.5; the IIHF's 67.4 is a bare pointer, so its penalty shot is 63.6 and its awarded goal 67.5)
Rule: Never cover the puck in your own crease with your goalie pulled — an awarded goal on the bare fact under NHL and IIHF 67.5, PWHL 69.5, Hockey Canada 10.2(a)(vi) and CARHA 58(c) Note 1; USA Hockey 614(b) and 618(a), and CARHA's own 36(b), add an obvious-and-imminent-goal test
Rule: Every book read here awards the crease penalty shot when the puck is in the crease — NHL and IIHF 63.6, PWHL 65.6, USA Hockey 614(b) and 618(a), CARHA 58(c), Hockey Canada 4.11(a)(v), which its 10.2(a)(v) cross-refers to; USA Hockey alone lets the other side — not you — elect a minor (406(a))
Rule: Puck outside the paint, you inside: a minor, not the shot, under NHL and IIHF 63.6, PWHL 65.6, USA Hockey's Casebook (614 Sit. 1) and CARHA 58(a)/(c); Hockey Canada 10.2(a)(v)-(vi) also go by where you stand: price the shot, or the goal with your net empty
Rule: Catching the puck is free; holding it is not. Height only sets the price — the crease runs four feet up to the top of the goal frame (NHL 1.7, 2.1), so above the crossbar is a minor and knee high in the paint the penalty shot (IIHF Situations 63.27 v 63.15, 67.4, worked applications, not rule text)
Never: Reach higher to hold a puck above the crossbar — once you are holding it, height only selects which penalty you pay, not whether you pay one; knocking it straight down is free at any height

In a scramble, a puck in the air at your own crease gets knocked straight down and played with your stick. Never close your hand on it, skate with it, turn away with it or fall on it — smothering it is your goalie's job. The catch itself is free; what comes after it is not, and with the puck inside your own crease the price is a penalty shot.

What costs you is what you do next, not how high the puck was. Holding it, taking a stride with it, turning to avoid a check or throwing it is what the books reach. Height only changes which penalty you pay — never whether you pay one — and reaching higher in a scramble puts your hands four feet up with sticks coming down. Knock it down and play it.

Moving with it does not cure it. The permission is to put the puck down immediately, not to carry it somewhere better first. Your goalie may smother it in the crease; you may not — and even the goalie can take a delay-of-game minor for freezing a puck they did not need to (see Goaltender).

What it costs.

The permission to catch. NHL 67.2: "A player shall be permitted to catch the puck out of the air but must immediately place it or knock it down to the ice." The IIHF's 67.2 and the PWHL's 69.2 carry the same sentence, and Hockey Canada's 10.2(a)(iii) and CARHA 61(a) exclude the honest catch from their hand-closing minors — a player who closes a hand on the puck and "immediately drops it to the ice" without gaining an advantage. USA Hockey's playing rules print no such sentence; its Casebook does (Rule 618, Situation 1): "⁠[t]he motion of catching, then dropping the puck, must be virtually one continuous motion". In your own crease (Rule 614, Situation 3): "if the puck is caught and dropped to the ice immediately, no penalty shall be assessed". So under USA Hockey the permission is a casebook interpretation rather than rule text.
What comes after the catch. NHL and IIHF 67.2(I) and PWHL 69.2(i) reach the player who "catches it and skates with it, either to avoid a check or to gain a territorial advantage". Hockey Canada's Interpretation 4 to 10.2(a)(iii) lists three acts, none of them a height: throwing the puck after closing your hand on it, trying "to maneuver around another player while holding the puck", and "tak[ing] a stride while holding the puck in their hand."
Outside the crease, under USA Hockey. A caught puck not dropped at once is a stoppage, not a penalty — "Play shall be stopped and a last play face-off shall occur" (618(a)), whose minor is for a player who "picks the puck up from the ice with their hand(s) while play is in progress." ⚠️ Covering a loose puck on the ice with your hand out there is a minor: 614(a)'s Note says "the use of hands to make the puck unplayable should be penalized promptly". Casebook Rule 614, Situation 1 gives a minor to a player who "slides and covers the puck with their hand". In the crease, a hand that closes and does not open is holding the puck — the penalty shot or optional minor under 618(a)'s third paragraph and 614(b).
Covering it in your own crease. If a skater other than the goalie "falls on the puck, holds the puck, picks up the puck, or gathers the puck into his body or hands from the ice in the goal crease area", the other team gets a penalty shot (NHL 67.4). ⚠️ With your own goalie pulled, the same act is an awarded goal (NHL 67.5), on the bare fact in five of the six books: the PWHL's 69.5, the IIHF's 67.5, Hockey Canada's 10.2(a)(vi) and CARHA's 58(c) Note 1 — "If the goalkeeper has been removed from the ice, then a goal is awarded". USA Hockey conditions it on the act having "prevented an obvious and imminent goal" (614(b); 618(a) says the same of the hand). CARHA's own 36(b), which Note 1 points to, carries that test too, so under CARHA play to 58(c): with your net empty, any cover in your crease is the goal.
Puck in the crease or you in the crease. NHL 63.6: "If the puck is in the crease, penalty shot. If the puck is outside the crease and gathered into the body of a player (other than the goalkeeper) who is inside the crease, minor penalty." Every book read here gives the shot when the puck is in the crease — Hockey Canada in 4.11(a)(v). The converse minor is rule text in the NHL, the IIHF (63.6, near-identical wording) and the PWHL (65.6, word for word). USA Hockey reaches the same outcome in its Casebook (Rule 614, Situation 1), on close but not identical facts, and CARHA conditions its shot on the puck being "within their goal crease" (58(c)), with the plain minor at 58(a). USA Hockey 614(b) judges "at the moment the infraction occurs", and only USA Hockey lets the other side elect a minor instead of the shot (406(a)) — their election, not yours, so never a discount.
Under Hockey Canada, price the shot whenever you are in the paint. Its 10.2(a)(v) gives the shot "when the infraction occurs inside the offending team's goal crease", words that could mean you or the puck, and 10.2(a)(vi) uses the same words for the goal. Its list at 4.11(a)(v) says "while the puck is in the goal crease", but a list does not cancel the rule's own wording, and Interpretation 5 has the player outside the crease as well as the puck, so it does not settle you in the paint with the puck outside. No Hockey Canada casebook is held here, so price the shot, or the goal with your net empty. USA Hockey's Casebook answers its own version of the question your way — "⁠[t]he location of the puck at the instant it is covered or held is the determining factor" (614, Situation 1), and batting a puck out of the crease into your body is "only a minor penalty" (Situation 4). But its player covers outside and slides in, so the exact NHL permutation is still unwritten there.
Height. All six books define the crease upward to the top of the goal frame — NHL 1.7, "extending vertically four feet (4') to the level of the top of the goal frame", and IIHF 1.7, Hockey Canada 1.5(c), the Note to USA Hockey 618(a), PWHL 1.7 and CARHA 5(c) alike. The IIHF Situation Handbook rules both ways: in Situation 63.27 a puck caught "(above the crossbar)" and thrown "was not considered to be in the crease", a minor; in Situations 63.15 and 67.4 a puck caught knee high, dropped and shot out is a penalty shot. In both, the player turned to avoid opponents — the conduct 67.2(I) reaches — so height changed only whether the minor became the shot. The Handbook ranks itself below the Rulebook, so read these as worked applications, not rule text.
Moving it. In Situation 67.6 a defender with their own net empty grabs a puck "out of mid-air (around the height of the waist)" and drops it outside the crease; the ruling is "an Awarded Goal to Team B."
Your goalie. The goalie's exemption is from the penalty shot only: in the crease only an opponent actually checking them excuses freezing it, and outside it an attacker bearing down does not (Rules 63.2(vii), 67.3(ii); IIHF Situation 63.1). Goaltender states plainly that how those two interact is a reading, because the NHL publishes no interpretation of it.

When the System Breaks

In short: When structure goes, get bodies to the net front and sticks in lanes, find the dangerous unmarked man, then count.

Priority: Bodies to the net front immediately — not to the puck
Technique: If you can't reach anyone, lie your stick flat in the passing lane through the slot
Read: Find the most dangerous unmarked player — scan the house, not the puck; in a scramble it is almost never the person holding it
Action: Count — outnumbered low, somebody high comes down and says so; even, match up loudly: "I've got 19", "you take the net"
Action: Get the puck out any way you can that keeps it in the rink — off the glass, never over it; a clear that concedes possession has still bought your team a change
Action: Reset before you attack — the commonest second goal is the one conceded straight after surviving the first
Key: The moment you realise you don't know your assignment, go to the middle — lost there, you cost your team less than lost anywhere else

Every system document describes an orderly world. A large share of your defensive-zone time will not look like that — often enough that it deserves its own plan: a broken play, a bad change, a puck ricocheting off shin pads, three of you below the goal line and nobody where the diagram says. (How large a share is not something anybody has published; the "roughly a third" figure you sometimes hear is not sourced and is not used here.) Systems don't cover this state, so players freeze, and freezing is what turns a scramble into a goal.

Here is the priority order when structure is gone. Work down it and don't skip.

1. Bodies to the net front, immediately. Not to the puck — to the front of the net. The most dangerous thing on the ice during a scramble is an unmarked player at the goalmouth, and the second most dangerous is nobody standing there when the puck squirts out. If you are the closest player and unsure what to do, go and stand between your goalie and the nearest opponent.

2. Sticks in lanes. If you can't reach anyone, lie your stick flat in the passing lane through the slot. Broken plays are decided by passes that shouldn't have got through. A stick on the ice is defence you can perform while out of position.

3. Find the most dangerous unmarked player. Scan the house, not the puck. Ask "who could score in the next two seconds?" and go and stand on them. In a scramble the answer is almost never the person with the puck — it's the person who's about to receive it.

4. Count. Are you outnumbered low? Then somebody high has to come down, and the person who does should say so. Are you even? Then match up, loudly: "I've got 19", "you take the net". A scramble ends the instant five people have re-agreed who has whom.

5. Get the puck out any way you can that keeps it in the rink. Once you touch it, get it out. Off the glass but never over it — from your own zone that is two minutes under the NHL, IIHF and PWHL books even by accident — around the boards, into the neutral zone, off a shin pad. Nobody is grading you. A clear that concedes possession has still bought your team a change and reset the coverage — which is the whole point.

6. Reset before you attack. When it's over, take the extra second to re-form. The most common second goal is the one conceded immediately after surviving the first, because everyone relaxed while three attackers were still in the zone.

The habit to build: the moment you realise you don't know your assignment, go to the middle — lost there, you cost your team less than lost anywhere else.

Clearing the Zone

Winning the puck is only half the job. The handoff from coverage into a breakout is where good defensive shifts become good shifts. Full detail in Breakouts; this is the transition itself.

Getting the puck out

In short: Decide before the puck reaches you, and never move it across the front of your own goal.

Action: Decide before you touch it — scan while the battle is still going, so you already know whether it's the winger, the centre or the glass
Never: Move the puck across the front of your own goal on the way out, with a pass or with your feet. Behind your own net is the route across, where an interception costs you almost nothing
Never: Turn your back to anyone coming at you, or duck, going back for a puck in your corner — keep your head up and your chin off your chest
Priority: Controlled exit whenever it is genuinely available, then a rim or a chip off the glass, then anything that ends the shift
Convention: Under low zone collapse the pass goes to the winger coming down the wall to between the hash marks and the goal line — not to the blue line
Never: Cheat up the ice — the puck should leave the zone before your third forward does, unless your team's breakout asks a forward to leave early — a centre fly, a slash or a stretch

Decide before you touch it. A defenceman receiving the puck and then starting to look is how a zone exit gets turned over, and coaches put it at the head of that list — coaching consensus rather than a counted ranking. Scan while the battle is still going — see Scanning and Anticipation — so that when the puck is yours you already know whether it's the winger, the centre, or the glass.

And one route is closed whatever you decide: not across the front of your own goal. Neither a pass nor your own feet go through the slot with the puck. If the play has to change sides, it goes behind your own net, where an interception costs you almost nothing — through the slot, the same interception is a point-blank chance against. Some teams exchange above the tops of the circles rather than behind the net, so ask which route yours wants; the bar on the slot route is the fixed half of it. Breakouts owns the cross-ice "over" and why it is the riskiest of the nine breakout options, and Defender states the same instruction for the pairing.

And on this play you are the one at the wall with your head over the puck, so the receiving posture is yours — in every league, checking or not. Unexpected contact happens in non-check hockey too, and the boards are just as hard. ⚠️ Never turn your back to anyone coming at you, and never duck. Get your skates parallel to the wall instead, forearm and hip to it, head up and chin off your chest — never the tip of your shoulder, and no part of the shoulder if you can help it. If you are already square to the wall and cannot turn in time, get your stick and gloves up and spread on the glass.

The turned back and the tucked chin are two prohibitions against two different injuries. A turned back converts the contact into a hit from behind, which you can neither see nor brace for; USA Hockey warns the player delivering one that "Even a light hit from behind could inflict a severe head or neck injury." A chin tucked to the chest straightens the cervical spine, and USA Hockey records that the injury from a head-down, head-first collision with the boards or a goal post can occur at walking speed. Its Introduction To Body Contact gives the shoulder rule — "Never hit the boards or glass with the tip of your shoulder – it can cause injury" — and, for a player checked while skating parallel to the boards, the broader "⁠[a]void hitting the boards with the shoulder". Body Contact and Battles, §6, covers the full three-case rule, and Breakouts carries it for the reverse and the rim.

The three outcomes, in descending order of value:

Controlled exit — a pass to a winger on the wall or the centre swinging low, and out with possession. Under low zone collapse your wingers are high on the points while the other team has the puck, and they come down the wall to between the hash marks and the goal line as you win it — that is where the pass goes, not the blue line. Being high is what makes the trip short; it is not the receiving position. Take this whenever it's genuinely available. See Breakouts.
Uncontrolled but safe exit — rim it around the boards, chip it off the glass, or bank it out. A rim is a hard puck sent onward around the boards, following the curve of the rink to the next teammate along; it is not a reverse, which sends the puck back against the flow into the space a forechecker has just vacated. Either way there is no possession, no chance against, and your team gets to change. This is a good play, not a failure.
Anything that ends the shift. When it's bad, it's bad. Get it out.

Structure first, speed second. It is tempting to leave the zone the instant the puck turns over, and forwards cheating up the ice is how a cleared zone becomes an odd-man rush the other way. Exit as a group. The puck should leave the zone before your third forward does — unless your team's breakout asks a forward to leave early — a centre fly, a slash or a stretch, so find out which your team plays before you treat an early exit as an error.

Rules that constrain the clear

In short: Clear it off the glass, never straight over it, or short enough to die in the neutral zone.

Rule: Off the glass and out is legal; putting the puck directly out of play from your own defending zone is a two-minute delay of game under NHL 63.2(iii), IIHF 63.2(III) and PWHL 65.2(iii) alike, with the same three narrow carve-outs — and no British rulebook held here amends the IIHF's
Rule: The NHL penalises a puck put over the glass "behind" the players' bench (Rule 63.2(iii)); the IIHF's Rule 63.2(III) reaches glass "surrounding" the bench — a wider word, appearing to reach the glass at the sides of the bench as well
Rule: USA Hockey 610(c), Hockey Canada 10.1(ii) and CARHA 75(b) are deliberate-only, and USA Hockey's 631(d) makes an accidental one a last-play faceoff; Hockey Canada's direct limb 10.1(v) names the goalie alone, as does CARHA 55(a) — so none writes the defending-zone minor the NHL, IIHF and PWHL do
Rule: Never flip it out deliberately, wherever you are on the ice — that is a two-minute minor under NHL 63.2(ii), IIHF 63.2(II), USA Hockey 610(c), Hockey Canada 10.1(ii), PWHL 65.2(ii) and CARHA 75(b)
Risk: An even-strength icing brings the puck straight back — under NHL, IIHF and PWHL rules your tired line cannot change and cannot take a timeout, though that bar has narrow exceptions and injury is one
Rule: Where your book grants shorthanded icing, it goes on the on-ice count, not the clock (NHL and IIHF 81.6, PWHL 83.6). A major expiring with the box empty is a bench minor (68.2; PWHL 70.2); an NHL or PWHL kill plays one short, unable to ice it, to the next whistle (20.3)
Rule: Under the NHL your goalie may play the puck behind the goal line only inside the trapezoid, unless a skate stays on the crease (27.8, 63.2(viii)). USA Hockey, Hockey Canada and CARHA write none, so there a corner puck is your goalie's to fetch too; a PWHL goalie plays as if it binds (65.2(viii))
Rule: No trapezoid is not no limit — a goalie who freezes the puck behind their goal line with their body out of the crease takes a minor under USA Hockey 614(c)(1) and CARHA 58(b), and Hockey Canada prices it too (clause v of Interpretation 3 to 10.1(a); Rule 10.2)
Rule: The goalkeeper's restricted area is IIHF 27.7, not the NHL's 27.8. The Elite League's Casebook does not switch it off; England Ice Hockey's R&R 22.3 call it "not currently enforced", scope and standing unsettled — under the IIHF book, play as though it binds: keep your goalie inside it

Use the glass and keep the puck in the rink. Off the glass and out is good, and so is a puck that dies in the neutral zone. Never flip one out deliberately, and from your own zone never put it straight over the glass. Aim clears wide and high off the glass, or short enough to die in the neutral zone — a long flat clear risks an icing, and under some books your tired line then cannot change. Shorthanded, where your league allows it, ice it freely while you are still below their strength. And know whether your goalie may fetch a puck in the corner, because that decides who retrieves it.

What it costs.

Over the glass, under the NHL. Under NHL 63.2(iii), shooting or batting the puck directly out of the playing surface from your own defending zone, with no deflection, is a two-minute minor for delay of game, whether or not you meant it. It has three narrow carve-outs: "except where there is no glass", and the NOTE's "⁠[w]hen the puck is shot into the players' bench, the penalty will not apply" and "⁠[w]hen the puck goes out of the playing area directly off a face-off, no penalty shall be assessed". Over the glass behind the bench is still a penalty. Clause 63.2(ii) is wider: a deliberate one "from anywhere on the ice surface" takes the same minor, so from the neutral zone you are safe only if it was an accident. Straight off a draw is unsettled — Rule 85.1 says no penalty, but no book reconciles that with 63.2(ii) — so never aim it out.
Over the glass, under the IIHF and PWHL. ⚠️ The IIHF writes the defending-zone rule too, at 63.2(III), which makes it a British player's rule, with the same carve-outs; so does the PWHL, at 65.2(iii). The IIHF's runs against you: the NHL penalises a puck "shot over the glass 'behind' the players' bench", the IIHF one over the glass "surrounding" it — a wider word, which appears to reach the sides of the bench as well. And the bench is not a target: IIHF Situation Handbook 63.24 still calls the minor on a clear that goes over the glass and lands in the bench, because "the determining factor… is where the puck leaves the playing surface". The Handbook ranks itself below the rulebook, so treat that as how it is officiated rather than as the rule.
Over the glass, under USA Hockey, Hockey Canada and CARHA. They write no defending-zone limb. Their minors — USA Hockey 610(c), Hockey Canada 10.1(ii), CARHA 75(b) — are for a deliberate one, and USA Hockey's 631(d) makes the accidental one a last-play faceoff in your zone; Hockey Canada's 10.1(v) and CARHA's 55(a) drop the deliberateness word only for the goalie. So find out which book your league runs before you decide how safe a high clear is.
Icing at even strength. A hard flat clear that reaches their goal line untouched brings the puck straight back for a defensive-zone faceoff, and under NHL, IIHF and PWHL rules your line cannot change (PWHL 83.4) and cannot take a timeout. The bar has narrow exceptions — NHL 81.4 permits a change "to replace a goalkeeper who had been substituted for an extra attacker, to replace an injured player, or when a penalty has been assessed which affects the on-ice strength of either team". IIHF 81.4 adds "a Player with a broken skate", but ⚠️ do not plan a change around it: the IIHF's own 82.1 lists only the NHL's three, neither says which governs, and an attempted change that is not allowed earns a warning and then a bench minor (IIHF 82.2(V), NHL 82.2(v)).
Icing and an injured teammate. Injury is in every list, in all three books: you never have to leave a hurt teammate on the ice to serve your own icing. IIHF Situation 81.7 reads the bar more narrowly than either rule, though the Handbook ranks below the rulebook — so make the change for the injured player rather than negotiating. ⚠️ If they are down and not moving, leave them where they lie and their helmet on — don't move them except to keep their airway clear — and get the first aider or medical cover to them; Team Play and Culture has the rest.
Icing under Hockey Canada. ⚠️ The no-change rule applies only in U18AAA, Junior and, at the Member's option, Senior (6.7(d)) — below that, icing costs you the faceoff and nothing else. Where it does apply, a change is allowed "⁠[w]hen a penalty or penalties have been assessed to either team", wider than the NHL's limb. You may take your timeout but not change during it (6.7(d)(iii)), where NHL and IIHF 87.1 and PWHL 89.1 all refuse it: the NHL's "No time-out shall be granted to the defensive team following an icing".
Shorthanded icing. A penalty-killing team may ice the puck with no whistle (Rule 81.6), subject to three limits, all owned by Special Teams. Two vary by book. USA Hockey gives the exemption only at Youth 15-Only and above, Girls 16U and above, High School and Adult (624(b)(1)). The NHL and the PWHL (83.6) withdraw it once a major expires with nobody in the penalty box to come out: the team plays a player short until the next stoppage, "not officially considered short-handed" (20.3). ⚠️ The NHL and IIHF (68.2) and the PWHL (70.2) also make that empty box a bench minor — and the IIHF requires the substitute "immediately" (68.2, and 8.1 for an injured player), so the two minutes can land on a kill already down a skater and make it a 5-on-3.
The head count. The third limit is in all six books: you are exempt while you are below their on-ice strength. A lone minor expiring puts you level and the exemption goes with it; on a 5-on-3 the first expiry leaves you 4-on-5, still exempt. Shoot while you are still below them and it is not icing, however late the puck lands. What the books do not share is the instant they judge, and Special Teams sets out which times it to what.
The trapezoid, under the NHL and the IIHF. Under NHL 27.8 and 63.2(viii) and IIHF 27.7 and 63.2(VIII), your goalie may play the puck behind the goal line only inside the trapezoid, on a two-minute minor for delay of game, unless a skate stays in contact with the crease. Retrieval outside it is on the defencemen. The KHL is commonly said to have one too; that is unverified here, with no KHL rulebook to check. The IIHF's own 2021 announcement dates its adoption to the 2021-22 season; the NHL's commonly given 2005-06 date is in no rulebook held here.
No trapezoid elsewhere. USA Hockey, Hockey Canada and CARHA write none — "trapezoid", "restricted area" and "designated area" appear in none of them, nor in USA Hockey's Casebook, save one Hockey Canada use about where the Goal Judge stands (5.4(b)) — so there your goalie is a genuine third puck-handler behind the net. A PWHL goalie should play as if it binds: its 1.8 and 27.8 switch the trapezoid off, but its 65.2(viii) still writes the minor for a goalie "who plays the puck outside of the designated area behind the net". How much rec, beer-league and youth hockey that covers is a question about leagues, and this document has no count for it.
No trapezoid is not no restriction. ⚠️ A goalie who freezes the puck out there takes a minor, so behind the net the goalie plays it rather than sits on it. USA Hockey 614(c)(1) and CARHA 58(b) price a freeze behind the goal line with the goalie's body out of the crease. Hockey Canada's clause v of Interpretation 3 to 10.1(a) is blunter — "When a goaltender leaves their crease, they will not be allowed to freeze the puck. If they do, they will be assessed a Minor penalty. No warning will be issued." — and its Rule 10.2 makes falling on the puck outside the crease a minor too. Clause ii of the same Interpretation lets the goalie come out to cut down the angle and, "after stopping the shot, cover the puck"; Hockey Canada never says which governs, and no Hockey Canada casebook is held here. But a cut-down-the-angle save is made out in front, not behind the net. For the skaters it is the same either way: a loose puck out there has to be moved, not smothered. See Goaltender.
🇬🇧 Under the IIHF book, play as though it binds. The IIHF book carries it at 27.7, and nothing in the Elite League's Casebook switches it off. England Ice Hockey's Rules & Regulations 22.3 say it is "not currently enforced" (its scope and standing are unsettled), and the IHUK In-House Rules do not mention it, though their Introduction says "⁠[u]nless otherwise stated, all rules will be enforced in line with the IIHF Rule Book". Assume it binds, ask your league, and remember that IIHF 27.7 turns on "the position of the puck", not on whether the lines are painted.

Common Mistakes

Not knowing which system you're playing. The root cause of most of what follows. Ask on day one.
Both defencemen drawn to the same puck with neither on the goalmouth. One pass beats five players. Somebody must have taken the goalmouth before you both go — even under a strong-side overload that sends both of you low on purpose.
Moving the puck across the front of your own goal — D-to-D through the slot, or skating it across yourself. Go behind your own net, or above the circles if that is your team's route — never through the slot.
Receiving the puck and only then starting to look. Scan while the battle is on, so that when it is yours you already know: winger, centre or glass.
Finishing a corner pressure into a back. Take the puck, take the ice, or angle them off it. If you can see their numbers, pull up — the second body in most of all, because it arrives late and unseen. ⚠️ No book here prices a hit to the back that stays off the head at two minutes, and in most of them it ends your game. Into the boards or goal frame when they cannot protect themselves, Hockey Canada and CARHA must make it a match. Under USA Hockey a forceful one on a player at the boards is a major and game misconduct or a match, and if it is reckless, plan on the match and a likely multi-game suspension (602(a)). Body Contact and Battles → Checking from behind has every tier.
Wingers drifting into the corner in a collapse system. Stay up on your point and let the corner be a two-player battle. Go down and you abandon the point and your best breakout outlet.
The weak-side winger failing to collapse when the centre goes low — or both wingers sagging at once. Under the collapse only the weak-side winger sags, and climbs back as the puck leaves the corner; under man-on-man the wingers follow their checks instead.
Chasing the puck instead of covering the pass. Hold your area — or your man, in a man system — with your stick flat in the passing lane.
Losing the man at the net front while watching the puck. Eyes on the puck, body goal side of the man. Turn square to the puck and they score from six feet.
Walking the screener out of the lane. Take the position and hold it, and as the puck arrives lift their stick low on the shaft, then let go. ⚠️ Driving them off their spot is interference wherever you play, and where checking is barred an illegal check as well — above two minutes once it endangers them, and a mandatory major and game misconduct under Hockey Canada if they are hurt. Legal checking does not make the walk-out legal. Under IIHF women's rules hold only ice you reached first, and under USA Hockey check the game, not the age group. The ladders are under Dealing with the screen.
Shoving a net-front attacker into your own goalie to get the goal disallowed. Hold your position, never push — the goal generally still counts, and the shove can be called on you. ⚠️ The attacker lands backwards on a goalie who is down and cannot see it coming, with the post beside them — coaching caution, since no source here counts injuries from it.
Cross-checking the net-front player. Lift their stick instead — up rather than sideways, low on the shaft, well below the bottom hand, then let go, stopping at their stick rather than carrying on into their head. ⚠️ The cross-check has no two-minute ceiling: in the NHL a major on severity alone brings an automatic game misconduct, and under Hockey Canada and CARHA one above the shoulders is a major and game misconduct whether or not anyone is hurt. The lift is not risk-free at the hands, but taken low it is much the cheaper.
Blocking a shot from a screening position, deflecting a puck your goalie never saw. Get out of the sightline, or take the inside on your man without pushing them, and let the puck through.
Blocking a point shot with your head in the shot lane. Shin pads to the puck, head up and out of it — never lift a leg, turn your back or sideways, or lunge. Stay on your feet until the puck is released.
Following your check into harmless ice in a man system while their teammate walks into the slot you left. Pick up the slot threat instead — and learn your team's rule for releasing a check.
Freezing when the structure breaks instead of defaulting to the house. Get a body to the net front and a stick in a lane, and say out loud who you have.
Holding a loose puck you have caught. Knock it straight down and play it with your stick. ⚠️ Hold it while the puck is inside your own crease and it is a penalty shot — with your own net empty, in most books an awarded goal. Under Hockey Canada standing in the paint can cost you the same. Smothering it is your goalie's job alone, and height only changes which penalty you pay, so never reach higher for it. The detail is in Handling a loose puck in your own crease.
Taking the contact at the wall with your back to whoever is coming at you — or ducking as it arrives. Keep your head up and your chin off your chest. ⚠️ A turned back turns the contact into a hit from behind; a tucked chin straightens the cervical spine, and USA Hockey records that a head-first collision with the boards or a goal post can injure it at walking speed. Body Contact and Battles, §6, owns the rule.
Cheating up ice before the puck is out. Leave when the puck leaves — unless your team's breakout sends a forward early (a centre fly, a slash or a stretch), so find out which yours plays.
Silent defending. Name your man out loud, and early — what you are about to do, not what you can see.

Check yourself

Answer each question before you go on — a real attempt, not a guess. Then go and check, because the checking is the part that does the work. Producing an answer and getting it wrong is worth more than recognising a right one, but only when the right answer follows: the section named with each question, and the Key Takeaways after them, are where you get it. Where the answer lives in another document, that is named too.

The puck goes into your corner and you are the weak-side winger. Do you leave the point? This has no single answer. Say what it depends on, and give the one question you can ask your coach that gets you most of the way. Then say what that question does not settle. (§How to Tell Which System Your Team Plays, §The weak-side winger's collapse, §Hybrid)
Their defenceman does not shoot from the point — they skate down toward the top of the circle. What do you do? There are three legitimate answers here; name them and say which system each belongs to. (§The walk-down from the point)
"Never both defencemen on the puck." That is not quite what this document says. State the version it actually gives, and say what stays true under every system. (§What Stays True Across Every Coverage System)
An opposing forward is parked in your goalie's sightline, outside the crease, not touching anyone. Is that legal? What may you do about it, and what is the one thing you must not do from a screening position? (§The point shot with a screen, §What Stays True Across Every Coverage System)
There is a loose puck in your own crease and bodies everywhere. What may you use on it, what must you not do, and what does the wrong choice hand the other team? (§The net-front scramble)
A goal goes in from the slot and the bench says somebody did not work hard enough. What does this document say almost always happened instead, what kind of call would have prevented it, and how well evidenced is it? (§Most defensive-zone breakdowns are not effort problems — coaching consensus, not a counted figure)
Structure is gone — three of you below the goal line, the puck loose, nobody where the diagram says. What is the first thing you do, and what is the default the instant you realise you do not know your assignment? (§When the System Breaks)

Key Takeaways

Find out which system your team plays before you need it. Ask: when the puck is in our corner, does the winger stay on the point or come down? Under the collapse the wingers stay high; under man-on-man they follow their check down; a hybrid marks man-on-man below the dots and looks like man coverage from the stands.
Under the collapse, with the puck in your strong-side corner: the strong-side defenceman goes to the puck, the weak-side defenceman owns the goalmouth, the centre comes down as the second body, and both wingers hold their points. When the centre goes low, only the weak-side winger drops into the high slot, and climbs back as the puck leaves the corner.
Whatever the system, defend the middle, the goal side and the next pass. Take away the pass into the slot before the shot from distance, stay between your man or area and your own net, make sure somebody has the goalmouth, and lay your stick flat in the next lane rather than chasing the puck.
Pressuring a player digging at your boards, play the puck or the ice — never their back. See their numbers? Pull up and angle them off it, above all as the second body in. ⚠️ No book here prices a hit to the back that stays off the head at two minutes, and in most it ends your game.
At the net front, get there first and take their stick, never their back. Inside shoulder ahead, no lean, no push. As the puck arrives, lift their stick low on the shaft, up not sideways, then let go — never on into their head; never hook, pin or grab it. ⚠️ No book here caps a cross-check at two minutes.
Beat a screen on your goalie by position — the referee will not move them. ⚠️ Never walk the screener off their spot: that can be called interference anywhere, and an illegal check too if your game bars checking. Never shove them into your goalie: the goal usually stands, you can be penalised, and they land on a goalie who cannot see them (coaching caution).
When their defenceman walks down from the point, play your team's answer — this is the collapse's real weakness. Under the collapse, follow a few feet, stay connected and call it; under man-on-man, go with them all the way; under a hybrid, pick them up as they cross the dots. Never give up the goalmouth to cover them.
Under man-on-man, switch on a crossing pair only when the trade is clean and called out loud; otherwise stay with your man. Do not follow them into harmless ice while their teammate walks into the slot you left. When to switch or release is your team's rule, not a law of hockey, so ask.
When structure is gone, go to the net front, not the puck. Bodies to the goalmouth, sticks in lanes, find the most dangerous unmarked player — usually the one about to receive it — and say out loud who you have. Get the puck out any way that keeps it in the rink, then reset. Lost? Go to the middle.
When you win the puck, never move it across the front of your own goal; decide where it goes before it is yours. ⚠️ Going back at the wall, never turn your back to anyone coming at you and never duck — head up, chin off your chest.
When you clear it, use the glass and keep it in the rink. Never flip one out deliberately — that is a minor in every book. ⚠️ Under the NHL, IIHF and PWHL books, a puck shot directly out of play from your own zone is two minutes even by accident — and British rulebooks leave the IIHF's unchanged.
Knock a loose puck at your crease down and jab it clear low with your stick; never swing. Smothering it is your goalie's job. ⚠️ Hold it with the puck inside your crease and it is a penalty shot — with your net empty, in most books an awarded goal. Under Hockey Canada, standing in the paint costs the same.

Rule 610, Situations 1 to 11, read in full on 2 September 2026 to test the claim that USA Hockey writes no defending-zone limb for a puck put out of play; they create none, and Situation 5 confirms the deliberateness requirement from the other side, holding that a goalkeeper who bats a rebound out of the rink takes no penalty and that a minor "would be required" only "⁠[h]ad the goalkeeper caught the puck first, thereby gaining control, and then deliberately batted the puck directly out of the playing area"; Rule 625, Situations 1 to 17, read in full for a screening or goaltender-vision provision, of which they have none; they run to stick and bench interference, the crease bar and a goalkeeper's abandoned stick (Situations 14 to 17, all under 625(c)), and Situation 10 states how flat that bar is — with an attacking player's stick or skates in the crease and the goalkeeper in it, the Referee "shall have no alternative but to disallow the goal" — while also limiting the face-off limb, answering "No" to whether play should be stopped every time and adding that "⁠[p]lay should not be stopped because a player momentarily places their stick and/or skates in the goal crease, unless they interfere with the goalkeeper in any manner"; Situation 9 limits 625(b)'s goalkeeper-out carve-out — the goal stands where the goalkeeper is "completely out of their crease", "However, if the goalkeeper is attempting to return to the goal crease and there is any interference by the attacking player who prevents the goalkeeper from making a play, then the goal must be disallowed and an interference penalty shall be assessed"; Rule 614, Situations 1 to 4, read 2 September 2026 because the playing rules alone do not settle the puck-outside case: Situation 1 answers the penalty-shot question "No. The Referee must assess a minor penalty" where a player covers the puck outside the crease and momentum "carries them into the goal crease with the puck", on the ground that "⁠[t]he location of the puck at the instant it is covered or held is the determining factor"; Situation 2 answers "No penalty shall be assessed" for a skater lying in the crease with the goalkeeper pulled and the puck shot under them, "provided there was no deliberate action by the player to cover the puck"; Situation 3 gives "⁠[e]ither a penalty shot or awarded goal" for one who catches, holds or gathers the puck while standing in the crease, and then prints the crease-case catch permission — "if the puck is caught and dropped to the ice immediately, no penalty shall be assessed as no stoppage of play has been caused (Rule 618(a))"; and Situation 4 puts the shot on a player lying outside the crease who pulls an in-crease puck into their body, while "⁠[i]f the player bats the puck out of the crease and into their body, only a minor penalty would be assessed"; and Rule 618, Situation 1, which carries the express permission the playing rules do not print — "⁠[w]hat guidelines should be followed in allowing a player to catch the puck and immediately drop it? The motion of catching, then dropping the puck, must be virtually one continuous motion", and "⁠[p]rovided the player catches the puck and drops it to their stick in one continuous motion, play should be allowed to continue". The playing rules volume was searched for a skater's permission to catch and has none: "catch" occurs there only in the goalkeeper's equipment specifications, in 618(c), and in the Sled Hockey section. Read for the screening, crease and handling questions only · Hockey Canada Playing Rules 2026-2028 (PDF) — Rule 6.7 Icing the Puck, read 2 September 2026 with clauses (a) to (e) and Interpretations, for the division scope of the no-change rule — 6.7(d) applying only "⁠[i]n categories of U18AAA, Junior, and at the option of the Member in Senior", the same scope in the same words at Rule 6.1(f), which cross-refers to it, and 6.7(a) to (c) containing no substitution bar of their own — 6.7(d)(i), whose three exceptions are the goalkeeper substituted for an extra attacker, the injured player, and, at (3), "⁠[w]hen a penalty or penalties have been assessed to either team, a change of players will be permitted", which drops the on-ice-strength condition the NHL and IIHF both impose — and 6.7(d)(iii), which permits the time-out that NHL and IIHF Rule 87.1 both refuse "to the defensive team following an icing"; Rule 7.7 Head Contact – Junior/Senior, read alongside Rule 7.6 because 7.6(b)'s automatic major for a cross-check above the shoulders is reprinted word for word in 7.7(b), so that limb is not scoped to minor and female hockey; Rule 7.5 Checking from Behind, read 26 September 2026 for the corner pressure — its preamble listing, among the situations referees are told to "strictly enforce", "⁠[w]here a player along the boards, with their head down looking for the puck or ‘digging the puck out,’ is hit from behind and driven head-first into the boards"; 7.5(a)’s "Minor penalty and a Game Misconduct penalty" for an intentional hit from behind "anywhere on the ice", with 7.5(e) making that Game Misconduct compulsory on any minor or major for checking from behind and 7.5(d) barring a plain misconduct; 7.5(b)’s Major plus Game Misconduct "at the discretion of the Referee, based on the degree of violence of the impact", mandatory where an otherwise-minor check injures; and both paragraphs of 7.5(c) — a Match penalty for a player hit "from behind into the boards or goal frame, in such a way that the player is unable to protect or defend themselves", and a second Match penalty, with no destination condition in it, for a player who "deliberately attempts to or deliberately injures an opponent by checking them from behind"; Rule 9.3 Slashing, whose definition exempts only "⁠[t]apping the stick of the puck-carrier… for the sole purpose of gaining possession of the puck" and carries no attempt-to-play-the-puck defence for a chop on the hands; Rule 10.1, read as all fourteen numbered clauses plus Interpretations 1 to 12, which between them create no defending-zone limb for a puck put out of play — Interpretation 5 instead narrowing the goaltender limb 10.1(v), so that no penalty follows where the puck leaves "where there is no glass" or deflects, and none at all unless "both ends of the rink" are similarly glazed; Interpretation 3 to Rule 10.1(a), read in full for all five of its clauses because clause v is routinely quoted alone: its preamble states the intent "to eliminate unnecessary stoppages caused by the goaltender", clause ii permits the goaltender to "come out of their crease to cut down the angle and catch the shot or, after stopping the shot, cover the puck", clause iv penalises without warning one who "comes out of their crease to beat an attacking player to the puck and simply jumps on the puck", and clause v is the freeze restriction outside the crease — "When a goaltender leaves their crease, they will not be allowed to freeze the puck. If they do, they will be assessed a Minor penalty. No warning will be issued." The Interpretation writes no sentence saying which of ii and v governs, and the rulebook was searched for one: neither "freeze" nor "act of playing goal" occurs anywhere else in it that resolves them, and no separate Hockey Canada casebook or situation volume is held here, so any reconciliation is a reading of the five clauses together, not a ruling. Rule 10.2 carries the rule-level text closest to the point — "A Minor penalty for Handling the Puck will be assessed to a goaltender who deliberately falls on or gathers the puck into their body or holds or places the puck against the goal, while outside their crease, thus delaying the game" — with the book searched in full for "trapezoid", "restricted area" and "designated area" — the first two appear nowhere in it, and "designated area" once only, at Rule 5.4(b), "Each Goal Judge will be stationed in the designated area behind each goal", which fixes where the Goal Judge stands and says nothing about the goaltender; Rule 8.5 Interference with the Goaltender and its Interpretations 1, 2 and 3: the crease bar, which is not flat and which opens "Unless the puck is in the goal crease area, a player of the attacking team may not stand in the goal crease" — the Goal Crease Area paragraph allows a teammate's goal where "the player who was in the goal crease does not attempt to play the puck, interfere with the play or obstruct the Goaltender's view or movements" — the definition of the foul as impeding the goaltender "by actual physical contact", Interpretation 3's goaltender-vision test, which reaches a player standing in the crease and no further, and Interpretation 2's direction that the referee "should also penalize the defending player who committed the initial foul"; and 8.5(b) and 8.5(c), the tiers above the minor — a major and game misconduct at the referee's discretion "based on the degree of violence of impact" and mandatorily for a player who "charges the goaltender" or who "injures an opponent by an Interference with the Goaltender infraction that would otherwise call for a Minor penalty", and a match penalty for attempting to injure or deliberately injuring a goaltender by interference — and Rule 7.3(a) Body-Checking, the minor for a player who "intentionally body-checks, bumps, shoves, or pushes any opposing player" in the divisions it names, and Interpretation 1 to Rule 8.2(a), which allows a stick lift "for the purpose of making a play on the puck" but says a hooking penalty "must be assessed" where it contacts the opponent's hands; Rule 8.2(b), under which the hooking major and game misconduct go only to a player who "injures an opponent by a hooking or butt-end hooking infraction that would otherwise call for a Minor penalty", against Rule 9.3(b), where the slashing major and game misconduct are the Referee's discretion "based on the degree of violence of the impact" and need no injury at all; Rule 9.5 High-Sticking – Junior/Senior and the list of interpretations printed under it, which makes an "attempted lifting of the opponent's stick" causing accidental head or neck contact and injury a double Minor, and "any aggressive, reckless, negligent or forceful action of the stick (e.g. pitchfork action in lifting the stick or hooking an opponent)" causing head or neck contact and injury a Major penalty and Game Misconduct under Rule 7.7 — the list itself naming no division, so its Junior/Senior scope is read from the rule it sits inside rather than from its own words; and Rule 7.6 Head Contact, which governs minor and female hockey instead, opens "There is no type of legal contact to the head, face, or neck", states that it "supersedes any other rules" except fighting, and whose 7.6(b) runs three paragraphs — a major plus a game misconduct at the Referee's discretion "based on the degree of violence of the impact", that same pair mandatory where a head-contact infraction that would otherwise be a minor injures the opponent, and that same pair again for a cross-check above the shoulders "whether or not injury results"; and Rule 10.2, whose preamble permits a player "to stop, knock down, or push the puck with their hand" and whose Interpretation 4 to 10.2(a)(iii) lists the three acts that do produce the minor — throwing the puck after closing the hand on it, trying "to maneuver around another player while holding the puck", and "tak[ing] a stride while holding the puck in their hand"; and Rule 10.2(a)(iii)–(vi), whose hand limb excludes "a player who closes their hand on the puck to catch or stop the puck and immediately drops it to the ice without gaining or attempting to gain an advantage", and which splits the offence into a hand limb (iii) and a body limb (iv) — "Deliberately falls on or gathers the puck into their body while standing or laying on the ice" — and escalates both to a penalty shot at (v) "when the infraction occurs inside the offending team's goal crease (see Rule 4.11 (a)(v) – Penalty Shots and Rule 1.5 (c) – Goal Crease)", and to an awarded goal at (vi) where the goaltender has been substituted for an extra skater; Rule 4.11(a)(v), which in the book as republished on 10 September 2026 (re-read 15 October 2026) reaches the hand and the body alike — a defending player who "closes their hand on the puck gaining an advantage, or deliberately falls on or gathers the puck into their body, while the puck is in the goal crease"; Rule 1.5(c), defining the crease as a space that "will extend vertically to the level of the top of the goal frame"; and Interpretation 5 to Rule 10.2(a)(v), whose ruling is on the body limb — "Assess a Minor penalty under Rule 10.2 (a)(iv)" — and whose reason is "The puck was not actually covered in the crease; therefore, no penalty shot may be awarded", though in its facts the player and the puck are both outside the crease at the moment of the cover; and Rule 10.1 Delay of Game, read in full for a defending-zone puck-out-of-play limb, of which it has none — 10.1(ii) reaches only "⁠[a] player who deliberately shoots, bats, or throws the puck outside the playing surface", with no zone limit, and the direct limb that writes no deliberateness word, 10.1(v), names "⁠[a] goaltender who shoots or bats the puck directly out of the playing surface, with their stick"; "glass" appears in Rule 10.1 only in Interpretation 5 to 10.1(a), which is about the goaltender's limb; and Interpretation 6 to Rule 10.1(a), which is where this book puts the shot-block carve-out the other three print as a Note to their falling-on-the-puck rule — a player lying in the goal crease with the goaltender removed and the puck shot under them and frozen there draws "No Penalty Shot or Minor penalty, provided that the player has made no deliberate attempt to cover the puck"; and Rule 4.8 Game Ejection & Game Misconduct Penalties, read 3 September 2026 for the consequence of an ejection — 4.8(a), removal for the remainder of the game and a report "to the appropriate Member or league for further action", and 4.8(c), the book's only automatic suspension for a game misconduct, which fires only "in the last 10 minutes of regular playing time, at any time in overtime, or after the conclusion of the game" and then carries "a minimum of the next regular league/play-off game or seven days" · IIHF Official Rulebook 2025/26 (Version 1.1, July 2025) — Rule 101.1 Illegal Hit in Women's Hockey, read in full: the permission to bodycheck "when there is a clear intention of playing the puck or attempting to 'gain possession' of the puck with the exception from the situation described in this rule" — two limbs and a qualifier, not one limb — the stationary player's entitlement to her ice, the bar on "⁠[a]ny move by a Player to step or glide into an opposing Player", and the minor / major-plus-automatic-game-misconduct range, Rule 69.1 Interference on the Goalkeeper, which carries a sentence the NHL's Rule 69 does not carry anywhere in 69.1 to 69.8 — "If an attacking Player is in the goal crease and does not leave immediately, the Referee has the possibility to stop the game and the subsequent 'face-off' shall take place at the nearest neutral zone face-off spot outside the attacking zone of the offending team", present in identical terms in the 2025/26 v1.0 and v1.1 and the 2026/27 book, and absent from the NHL, USA Hockey and Hockey Canada volumes searched in full, including across line breaks, Rule 55.1 Hooking, whose hands sentence has no counterpart in the NHL's and whose very next sentence reads "When a Player is checking another in such a way that there is only stick-to-stick contact, such action is not to be penalized as 'hooking'", a tension the book does not resolve, and Rule 61.1 Slashing, which reproduces the NHL's hands sentence word for word, with 55.3 and 61.3, each headed "MAJOR PENALTY AND GAME MISCONDUCT PENALTY" and each turning on the Player recklessly endangering the opponent rather than on injury — so the IIHF hooking major, unlike the NHL's and Hockey Canada's, reaches an uninjured opponent, and Rule 63.6, whose "significant factor" sentence is the NHL's word for word but for the capitalised and quoted "Penalty Shot", with "goal crease" for "crease" and full clauses where the NHL's are elliptical — while IIHF 67.4 has no operative text of its own, reading in full "This rule is described under" and pointing to Rule 63.6, Rule 67.2, whose permission sentence is the NHL's word for word but for the capitalised "Player" — "A Player shall be permitted to catch the puck out of the air but must immediately place it or knock it down to the ice" — Rule 1.7, under which the Goal Crease Area "extends vertically until the top of the crossbar", and Rule 63.2(III), which carries the NHL's defending-zone puck-out-of-play minor in the same terms and not word for word: the determining-factor sentence and both Note carve-outs match, but its own carve-out reads "except where there is no protective glass" against the NHL's "no glass", and its bench clause penalises a puck "shot over the protective glass surrounding the Players' bench" against the NHL's "behind" — "surrounding" being the wider of the two — with 63.2(II), the deliberate limb from anywhere on the ice, and 63.2(VI), which penalises the goalkeeper who "“races out” of their goal crease in an attempt to beat the attacking Player to the puck and instead of playing the puck jumps on the puck causing a stoppage of play" and whose Note then makes the other case legal — "If a goalkeeper comes out of their goal crease to “cut down the angle” on a shot and after making the save covers the puck, this shall be legal"; verified unchanged in the IIHF Official Rule Book 2026/27 (Version 1.0, June 2026), which was read for that rule and nothing else; Rule 81.4, read 2 September 2026 in the 2025/26 v1.1 and 2026/27 books, whose exception list runs to four — "to replace a goalkeeper who had been substituted for an extra attacker, to replace an injured Player, a Player with a broken skate, or when a penalty has been assessed which affects the on-ice strength of either team" — against Rule 82.1, which states the same bar a second time under a trigger naming "➔ Rule 63.8 – Delaying the Game or ➔ Rule 81 – Icing" and lists only three, the broken skate absent, in both editions, with neither rule cross-referring to the other; the 2025/26 books were searched whole for "broken skate" and it occurs once only, in 81.4 (the 2026/27 edition prints it a second time in Appendix VII, Developmental Rules for Piloting, attached to a different offence and expressly not in force, so it bears on nothing here), read with Rule 82.2(V) for the consequence of an improper change; Rules 81.6 and 20.3, read 14 September 2026 in the 2025/26 v1.1 and 2026/27 editions alike, for the negative — 81.6 carries only the two paragraphs the NHL states first and no major-penalty paragraph at all, and 20.3 requires that the offending team "must place a substitute in the penalty box immediately", which forecloses the failure the NHL's 81.6 penalises; Rule 27.7, the goalkeeper's restricted area — "A goalkeeper shall not play the puck outside of the designated area behind the net… The determining factor shall be the position of the puck. The minor penalty will not be assessed when a goalkeeper plays the puck while maintaining skate contact with their goal crease" — read with Rule 1.8, which gives the marking as "6.80m" along the goal line and "8.60m" at the boards, and with Rule 63.2(VIII), the same two-minute minor; Rule 69.4's returning-goalkeeper clause — which reaches only a goalkeeper who has already played the puck outside the crease and is "then prevented from returning to their goal crease area due to the deliberate actions of an attacking Player", where that Player "may be penalized" — unchanged across the 2025/26 v1.0 and v1.1 books and the 2026/27 book, and matched at the NHL's own 69.4 in the NHL's wording; Rule 69.1, the source of the positioning quotation above, whose limb (I) disallows a goal where an attacking Player "either by their positioning or by a 'relevant contact', impairs the goalkeeper's ability to move freely within their goal crease or defend their goal", read with Appendix IV, Table 16 (Interference on the Goalkeeper situations — Situations 5C and 5E, both answered "Goal is allowed", read 2 September 2026 in the 2025/26 v1.1 book and again in the 2026/27 edition, where the same table is renumbered Table 14 and the rows are identical), and with its premise that an attacking Player's position "whether inside or outside the goal crease, should not, by itself, determine whether a goal should be allowed or disallowed"; and Rule 67.5 Awarded Goal, which awards the goal for equipment or obstacles left at the net only where "the goalkeeper must have been replaced for an extra attacker, otherwise a minor penalty shall be assessed"; and Rule 23, read 3 September 2026 for the consequence of an ejection — 23.1, the balance of the game with twenty minutes recorded; 23.2, the report to the Proper Authorities; and 23.6, which writes no automatic count of its own, saying only that "⁠[t]he respective process is outlined in the IIHF Disciplinary Code" — the IIHF Disciplinary Regulations (in effect 6 October 2025) were read in full on 15 October 2026: they write no per-offence tariff, and their Article 10 suspensions are served in IIHF Events, so this document states no IIHF suspension consequence for league play · IIHF Situation Handbook 2025/26 (Version 1.1, August 2025) — Situations 81.6, 81.7 and 81.8, read 2 September 2026 in this edition and in the 2026/27 handbook, in the same words in both: 81.6 and 81.8 cite "Rule 81.4; Rule 82.1" jointly as one bar and do not distinguish their exception lists, and 81.6 refuses the change for coincidental fighting majors because they "⁠[do] not affect the on-ice strength of either team" — the condition Hockey Canada's 6.7(d)(i)(3) omits; Situation 81.7 answers a question about a lengthy delay for broken glass, and its answer is wider than its question — "No. Only time a line change is permitted is when a penalty is assessed which affects the on-ice strength of either team" — a sentence narrower than the list in either rule, which is why the Rulebook rather than the Handbook is treated as governing above, on the Handbook's own Foreword; Situation 63.27, where a puck caught above the crossbar "was not considered to be in the crease. Therefore, only a minor penalty is warranted", against Situations 63.15 and 67.4, where a puck taken knee high in the crease is a penalty shot — in all three of which the player also "turns to avoid" opponents before releasing the puck — and Situation 67.6, where a defender with their own net empty grabs the puck "out of mid-air (around the height of the waist)" and drops it outside the crease, ruled "an Awarded Goal"; and Situation 63.24, on the bench, which still assesses the minor where a clear goes over the glass and lands in the Players' Bench — "the determining factor when deciding whether a delay of game penalty is to be assessed, is where the puck leaves the playing surface", judged on "an imaginary plane that continues upwards to the roof from the top of the glass", exempting only a puck "shot directly into the Players' Bench (where there is no glass)" — read in the same words in the IIHF Situation Handbook 2026/27, which was read for that situation and nothing else; its Foreword ranks it below the Rulebook — "in case of any contradictions, the valid IIHF Rulebook is always the basis" · Scouting The Refs – Hand Pass Hysteria · Scouting The Refs – Puck Over Glass Penalty · Hockey Canada Rule Book – Rule 1.5 Goal Crease · IIHF – New Rule Book for global game — the IIHF's own announcement, 5 June 2021, that it would "introduce a new Rule Book for the 2021/22 season", listing among the rules to be integrated "A restricted area for goalkeepers behind the net to create more offensive play (i.e. trapezoid familiar to NHL and KHL)". It dates the IIHF's adoption, and it is the only support held here for the KHL — a governing body's aside rather than a KHL rule. Nothing held here dates the NHL's own adoption · England Ice Hockey Rules & Regulations 2024-2025 (PDF) — Rule 22.3, “Goalkeepers’ Restricted Area is not currently enforced to allow ice rinks the necessary time to make the changes to implement this rule”, the sentence quoted above · IHUK In-House Rules 2026-27, Revision 1 (published 25 July 2026) (PDF) and the superseded IHUK In-House Rules 2025-26, Revision 1 (PDF) — neither amends Rule 27, and both carry the Introduction’s “Unless otherwise stated, all rules will be enforced in line with the IIHF Rule Book”. Both editions searched and read on 16 September 2026 · IHUK WNIHL Rules of Competition 2026-27 (PDF) — the "Game Length & Format" table, "WNIHL U16 | 3 x 15 minute periods | Full ice, non-checking, stop clock" and "WNIHL | 3 x 20 minute periods | Full ice, non-checking, stop clock", read 1 October 2026.

Boards safety (the receiving posture on the zone exit — Body Contact and Battles, §6, owns the full three-case rule and the qualifications on the research beneath it): USA Hockey — Introduction To Body Contact (PDF) — item 1 "Angling In" of its Heads Up Hockey teaching list, for "Never hit the boards or glass with the tip of your shoulder – it can cause injury", and its teaching points for a player "checked while skating parallel to the boards", for "Press your forearm and upper thigh (hip area) against the boards" and the broader "Avoid hitting the boards with the shoulder" — broader than the tip and softer than never, which is why the instruction above is written as the tip never and no part of the shoulder if you can help it · USA Hockey — Heads Up Hockey Program Guide (PDF) — its "Checking from behind" passage, for "Even a light hit from behind could inflict a severe head or neck injury", and "How spinal injuries happen in hockey" for the cervical-flexion mechanism and for "A player doesn't have to be going at full speed for this to happen — it can occur at walking speed". ⚠️ That walking-speed sentence's "this" points back to the spinal injury in the preceding sentence, and it is stated of the head-down collision rather than of a turned back, about which USA Hockey writes no such thing. All four strings located in the manual on 22 September 2026. ⚠️ The manual's technique teaching is not a rule citation, and this edition is built on the 2007-09 USA Hockey rulebook, so any rule stated in it may since have been superseded.

The absent trapezoid, fifth and sixth books, read 23 September 2026: CARHA Hockey Official Rule Book (2026 edition; first read in the 2020 printing on 23 September 2026 and re-checked in the 2026 edition on 15 October 2026, with the same result) — the words "trapezoid", "restricted area" and "designated area" return nothing in it, so its absence is a silence like USA Hockey's and Hockey Canada's. CARHA governs CARHA-affiliated leagues only. PWHL Official Rule Book 2025-2026 (PDF) — this one is not a silence: Rule 1.8 "Goalkeeper’s Area" reads "⁠[n]o restricted Goalkeeper’s Area, which will be known as a ‘trapezoid’ will be enforced" and Rule 27.8 "Restricted Area" reads "⁠[t]he PWHL does not apply a restricted area for goalkeepers." ⚠️ The book contradicts itself once and it is recorded rather than smoothed away: its Rule 65.2(viii) still carries the NHL’s "On a goalkeeper who plays the puck outside of the designated area behind the net", and its summary table of goalkeeper penalties still lists "Playing puck in restricted area". Also Rule 83.6, read 15 October 2026, which carries the NHL's 81.6 paragraph barring icing to a team that has left nobody on the penalty bench to come out when a major expires. ⚠️ Rule numbers are cited and page numbers are not, deliberately: eleven pages of this PDF carry the previous season’s running header, so a page-based citation from it can date the book a full season wrong — the edition here is taken from the title page. Nothing in either book beyond the rules named was read for this document. The bench minor for an empty penalty box, read in the primary text on 14 September 2026 — Rule 68.2 in the NHL's book and in the IIHF's, whose closing sentence is common to both word for word, with IIHF Rule 8.1 saying it again for an injured player and Rule 20.3 in each book for the duty itself. The IIHF text is identical in the 2025/26 Version 1.1 and 2026/27 editions. Special Teams carries the other three books.

CARHA on the empty-net cover, read in the rulebook text on 15 October 2026 (CARHA-affiliated adult leagues only): Rule 58(c), the penalty shot for a defender who covers or picks up the puck "while the puck is within their goal crease", and its Note 1, "If the goalkeeper has been removed from the ice, then a goal is awarded.
