i dont think you can make it do a fast serve, i think it just does it at random spots in
the game

hold b when serving

Just hold the wii remote in what ever had you are holding it in then just swing the wii
remote as fast as you can if wrong sorry ok.

swing when the ball is high up in the air then swing as hard as you can if wrong sorry its
just what i do

u smack the ball WHEN IT IS AT IT'S HIGHEST POINT
