Wraparounds work when the goalie overcommits to one side or when a player has enough speed to get the puck around the post before the goalie reacts. They can also create rebounds that teammates can score on.

Deke
A deceptive move to fake out a defender or goalie. The word comes from decoy. Dekes can involve moving the puck from forehand to backhand, faking a shot, or using your body to sell a move in one direction while going another. The best dekes look effortless because the player has practiced them until they are automatic.
