A player with a quick release can go from handling the puck to shooting in a fraction of a second. They do not need a big wind-up or perfect position. This is what makes shooters like Ovechkin or Matthews so dangerous. The goalie knows the shot is coming but the release is so fast they still cannot stop it.

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.
