Forechecking is a defensive strategy used in ice hockey to pressure the opposing team when they have the puck in their own zone. The goal is to disrupt their ability to move the puck and create scoring opportunities for the forechecking team. Players will often position themselves near the puck carrier and cut off passing lanes to regain possession. There are different types of forechecking systems, such as the 1-2-2 and 2-1-2 formations, which refer to the arrangement of players on the ice. Effective forechecking can lead to turnovers and quick scoring chances, making it a crucial aspect of a team's overall game plan.
