First post/tip from the guide.....I'm certain there will be many others to follow.
Shooting
This is one of the most dynamic aspects of the game, and understanding how it works in FIFA 09 can determine just how much success you will have. Many factors determine the accuracy of the shot such as player momentum, speed, rating, and of course how far you power up the shot meter. In the “Shot Power/Elevation Chart,” you can clearly see there is a direct correlation between shot speed and ball elevation based just on the how much you power up the shot meter. Also keep in mind that your player’s accuracy is greatly diminished if he is on a full sprint while shooting, as well as his lateral momentum at the time. A really good tip here is to let go of the sprint button, control your pace to gain composure, get the ball on your player’s preferred foot, and then let it rip. This is not always possible and sometimes you just have to wing it! 
However, this would be a good place to also use the various “Face the Goal” options mentioned in the dribbling section. The shot can be very frustrating if not practiced, so take some time in the arena to get it down from various locations. When you get comfortable with it, you can create some great highlight reels.
Oone tip that works very well if your player is right footed, is to head directly at the goal about 5 yards off of dead center and as soon as you see the keeper, start to move left. Flick the left stick and just barely tap the
shot button, and sit back and watch the ball rip into the opposite side netting for a goalaso! Obviously, the opposite movement should be done if your player’s favoured foot is left.>
Shot
This refers to the out and out strike on goal with maximum speed, also known as a “driven shot.” This is what puts fans in the stands and makes this game so much fun to play. Refer to the “Shot Power/Elevation Chart” to see what factors come in to play to make the shot go where you want it to. You can greatly control the rise of the ball and speed based on what is shown in the chart.
Finesse Shot
This is a very effective tool to help assist your player in gaining composure while striking the shot. A direct shot is hit with the boot laces, whereas the finesse shot is usually taken with the side of the foot. This is a placement shot versus a driven shot. You get much more accuracy in putting the ball in the net where the keeper least expects it. If you have to approach the goal at pace due to pressure and/or slightly off balance, then just get in the habit of hitting a finesse shot and your chances will be pretty good to get the shot on net.
Chip Shot
The chip is a cheeky little shot that totally fools and humiliates the keeper in one simple lofted scoop shot. Much like the same term in golf, it basically is a shot hit under the ball with the foot stopping upon impact to loft the ball with a high trajectory in the air for a short distance. Usually this is right out of the keeper’s full stretch, and is best performed the second you see the keeper start off his line. Practice this in the arena as it is very effective when coming at the keeper one- on-one. And remember, timing is indeed everything with this one.
