I'm just learning the skill stick myself. There are a lot of things you do in this game. Some help:
Slap shot - a really hard shot where you take a back-swing and hit the puck hard.
wrist shot - No backswing, when you just take a shot by flicking it with the stick.
deke - a trick move where you try to fool the defender. The deke button is very context sensitive.
saucer pass - when you pass it by lifting it off the ice so that it will go over defender's sticks.
Check - hitting the opponent . . . you are only supposed to do this to the person with the puck.
Poke check - when you use your stick to try to grab the puck from an opponent
One-timer - when someone passes you the puck and you immediately try shoot with a slap shot such that you only touch the puck once.
Many thanks!
