I really suck at aiming myself. The thing I do wrong is that I allways move the LS 100% in the direction I want to shoot. This is because most online games are intense with very little time to take shots, so in an effort to take a quick shot I move both the LS and RS too fast and too hard. The trick to aiming is to aim soft. Aiming is sensitive. If you aim the left stick all the way left, your will miss the goal a lot of times (especially one-timers) unless you're controlling a player like Ovechkin. So if "all the way left" is 100%, then go about 75-80% left to get a shot that will stay inside the goal. Also note that when moving the RS to take a shot, moving it as fast as you can won't make for a harder shot or anything, but may affect your aim if you're not inside the "shoot margin" - 11-13 o'clock.

Also, on onetimers, you will hit the net a lot more if you wait with moving the RS until you've received the pass. I tend to move the RS right after sending the pass away with the result that I miss the puck all together from time to time.

If you want to score you need to change your aim all the time. If you don't and for example allways aim high on the goalies stickside -  the goalie's going to notice and expect it. Vary your aim and the goalie will guess wrong, making the wrong move from time to time, and thus increasing your chances to score.

Scoring is about forcing the goalie to leave an opening and then exploiting that opening.

In this clip I take two slapshots. First time, I aim low stickside and the goalie makes the save. Next time, taking a slapshot, the goalie guesses I'm going to aim low again and goes down with his pads, leaving the topshelf open.

The easiest way to light the lamp in NHL 10 is by putting the puck on net and having a teammate swoop in to clean up the rebound while the goalie is still recovering from the first save. Pulling off a successful rebound goal comes down to two factors:


Shot location
Teammate positioning


The shooter should aim low, far side post, to generate a rebound that bounces towards the middle or other side of the ice; however, knowing when to unleash the shot can be just as important as knowing where to place it.


Look at my earlier posts:


Wrist shots generate better rebounds
Rebounds


Ideally, you want to shoot the puck a stride or two after your teammate crosses the blue line. This way he will be hitting the crease right as the puck comes off the goalie’s pads. Once you get the timing down, the rebound becomes one of the easiest ways to create scoring chances in NHL 10.


Deflections/Screens


For whatever reason, the default "screen effect" in NHL 10 is significantly lower than what it was last year, so screen goals are much less prevalent overall than they were in NHL 09. To compensate, NHL 10 adds several new animations for deflections, including some that let you "bat in" pucks that are hanging in mid-air.


All the deflection animations are randomly generated, so all a player can do is to face the shooter (by holding the left trigger/L2) and keeping his stick in the shooting lane.


Forget about trying to screen the goalie -- deflections are NHL 10's tactic of choice in front of the net.


If you’re going for a deflection it’s important to take the shot when a team mate is positioned outside the shooting lane,  so that the puck does not end up hitting him instead of his stick.


Dekes


Like many things in NHL 10, the effectiveness of your dekes depends largely on your player rating. Generally speaking, a player with a deke rating in the range of 80-85 should be able to fake a goalie out with one or two simple dekes. For players with lower ratings, more dekes are often necessary to get the goalie out of position and open up a shooting lane.
Remember to move both your body and your stick.


Look at my earlier deke posts.


One-Timers


NHL 10 removed the tape-to-tape passing from the earlier games which makes it a bit more difficult to generate one-timer goals in NHL 10, but if you can make the pass and your aim is right, the actual shot will go in more times than not.
A play like this will almost certainly light up the lamp.



When finishing the one-timer, try to aim your shot at one of three places:


Near-side top shelf
Five hole
Low opposite corner


What I wrote about onetimers in NHL 09 still applies: More on scoring in NHL 09
With proper positioning, the one timer makes for a great tactic against defenses that over pursue the puck carrier during an odd-man rush; however, if teams start playing the pass and guarding against the one-timer, the puck carrier might want to think about shooting low at the goalie’s pads to generate a "bank pass" for a rebound goal.


It may not always be pretty, but with goalies still being as superhuman as ever in NHL 10, sometimes you have to think like a video game to score in a video game.

In real life, most goals are scored below knee level, and on the goaltender's stick side. When the goaltender is sprawled across the ice (typically when you attempt a onetimer or a deke), the upper corners are left open.

When playing NHL 10, try moving the RS as close to 12 o'clock as possible when you shoot. The quality of your shot will be much better if you end up with the RS at 12 then if you end up at 11.
