Looking at different forums I've seen complaints about one-timers not resulting in goals very often. This is true. In previous games it was easier to score with one-timers. I actually think NHL 09 is more realistic, since it's harder to aim when you take a quick shot at a moving puck. Another reason for one-timers not working is the fact that the AI learns from you moves. If you keep doing the same kind of one-timers all the time, the goalie will notice and adjust to that.

So you need to change things up. Here's a few examples:

First a standard one-timer, 2 on 1.



Next time when I make the same move, the goalie recognizes the situation and makes a great save.



So I need to change my play. Fore instance instead of taking a direct shot I pass the puck back - let's call it a two-timer.



Also I should take some direct shots.



Now If I keep mixing my approach in the offensive zone up the goalie can't be sure as to what I will do - this makes scoring much easier. RS is also of importance - try to move it up as straight as possible, as this affects your aim.
