Video Notes:
0:32 – all 3 criteria must be met
0:51 – defender starts not in a good position to check. She is not within marking distance. Even when the first defender gets within marking distance, the attacker is holding her stick on the far side from the attacker as she runs down the field. If defense tried to check in HS, this would have ended up being an across-the-body check. So the defender is not in good position to check and the count does not start.
0:54 – when the attacker cuts back inside (and the video pauses), she exposes her stick and now both defenders are within marking distance and in good position to check and have both hands on their stick, so the count starts
1:22 – note that you say “ONE” and “ONE THOUSAND” out-loud. Not just “ONE” “TWO”
1:48 – they pause the video at the point where the defender comes within marking distance of the attacker. Note the defender has both hands on her stick and the attacker has the stick head on the same side of her body as the defender (i.e. she didn’t switch hands). So now all 3 criteria are met and the count can start.
2:03 – this shows how the attacker can get the count to stop. If she turns her body away so that now the defense would have do check across the body in order to try the check, the defense is no longer in a good position to check and the count stops. It restarts (at 2:10), when the 3 conditions are again met.

2:21 – see how the attack player turned away from the defense so that 18 was no longer in a position to check? That would reset the count.
2:26 – again, attack has her stick on the far side. No count

The CAPLAX rules sheet has information helpful for officials, coaches, and players about 3 seconds closely guarded

Offense cannot hold ball for more than 3 seconds, if :
DEFENSE: Guarding closely(inside stick length); both hands on stick; in position to legally check

REFEREE:
3 Second Count must be AUDIBLE

OFFENSE: Can stop 3 second count by: keep stick in uncheckable position; separate from defender by stick length; Switch Hands to uncheckable position; put stick into legally checkable position (i.e. below the shoulders in a modified checking level)

Typically a Transition Foul

Coaches should teach players that when they hear the official starting to count, they should immediately do one of the responses listed under “OFFENSE” above.
