The object of the game of ice hockey is to score more goals than the opposing team. Goaltenders and defencemen are concerned primarily with keeping the other team from scoring a goal, while forwards are primarily concerned with scoring goals on the other team. Forwards also have to be defensively responsible while defencemen need to press offensively, and it is not unknown for goalies to attempt to position the puck for a counterattack, or even attempt to shoot against an unguarded net.
