In ice hockey, a forward is a player position on the ice whose primary responsibility is to score and assist goals. Generally, the forwards try to stay in three different lanes, also known as thirds, of the ice going from goal to goal. It is not mandatory, however, to stay in a lane. Staying in a lane aids in forming the common offensive strategy known as a triangle. One forward obtains the puck and then the forwards pass it between themselves making the goalie move side to side. This strategy opens up the net for scoring opportunities. This strategy allows for a constant flow of the play, attempting to maintain the control of play by one team in the offensive zone. The forwards can pass to the defence players playing at the blue line, thus freeing up the play and allowing either a shot from the point (blue line position where the defence stands) or a pass back to the offence. This then begins the triangle again.
