When playing the trap, the centre typically spearheads the defence by placing himself/herself in the middle of the ice between the red line and blue line in defensive position. This forces the puck carrier to either side board where the centre and puck side winger close him in, "trapping" him/her between the two defending players and the boards. Here the attacking player has very few options, and generally must retreat to a defenceman, whereupon the defending team can reset the trap. This tactic was pioneered by the New Jersey Devils in the late 1990s and has been used extensively in the NHL and all levels of hockey since.
