Since you from Sweden I am gonna assume you are going to be playing on a Garlando or possibly TecBall??? Anyways, the table probably isnt going to make much of a difference. I think you will have plenty of time to be able to work on your ball control and shooting. Checking out the pic of your table, ball control practice is gonna be hard... and I am sure that if you shoot on that thing enough times the rods are going to bend like tin foil.
The advice I have for your match is to make sure that you have 2 of your defenders in front of your goal at ALL times and make sure that they arent directly in front of each other... spread them out just alittle over a ball width apart. Alot of times beginners totally forget about where their back guys are... also I would put directly in the middle of the goal when the other guy has the ball in the back... chances are he isnt going to be able to pick out holes.
As far as practice goes. At the start of any practice session just thow the ball in and work on hitting it in between every guy. I agree with Chase on that if you can control the ball, the game will be alot easier for you and you will not turn the ball over as much as the other guy. Just work on this for about a half an hour to an hour. Doing this everyday you will have gained enough skill to be able to control the ball.
When you practice shooting, NEVER place the ball where you want it with your hand. Always set your shot up as if you are in a match. That is where the ball control skills come into play. Not knowing how long you have been playing, I probably suggest a simple pull kick. It is a shot that alot of beginners use cause they can hit the ball harder than a push kick and more times than not it is more comfortable to shoot. Basically just practice what you see in that youtube video, and make sure you use all of your options with that shot in the match.
If you get the ball on your 5bar, hit the crap out of it and try and hit it towards the goal. Thats what I do when I play...
Have fun and good luck! Need any more tips let us know...
