hmm hockey is one of those games where its hard to really teach you how to be good at because so much of it is on the fly whereas baseball i could say okay on a 3-0 count and your 8th man is up, take pitches all the way until 2 strikes, etc.
i will quote the best pure goal scorer of all time "you miss one hundred percent of the shots you don't take" -gretzky
gretzky was really good at creating space and dangerous behind the net as well he was very patient with and without the puck. Gretzky didn't score 892 goals just because he was great with the puck but he was even better without the puck.
if you are having trouble getting past defenders learn to shoot the puck through defenders legs, or learn the deke moves, use the saucer pass, (for a beginner i would suggest 'Crash the net' for offense and once you cross the blue line just shoot it low and hard and try to bang in a rebound. for forecheck try a 1-2-2 low or 2-1-2 low and for defensive pressure go with puck side attack and breakout go with aggressive or normal if you don't use your defenders at the point.
if you like when 13 comes out you could add me and i could show you how its done

as i am a skilled gamer especially at NHL (don't know if it's something to brag about but i am pretty awesome at nhl lol)
