Backchecking is a defensive strategy used in ice hockey to prevent the opposing team from scoring. When a player on the offensive team has the puck, defenders skate back towards their own goal to intercept passes or block shots. This helps to disrupt the offensive play and regain control of the puck. Effective backchecking requires players to be aware of their surroundings and communicate with teammates. It involves quick skating and positioning to ensure that opponents are closely guarded. Good backchecking can turn the tide of a game by preventing scoring opportunities and creating chances for the defending team to counterattack.
