Re: Question about serving
Well, from experience, when you serve to your left (supposing you're right-handed), you just do a more natural movement, as the serve movement itself is "closed", that means, the follow-through goes in that direction. When you serve to your right, you should do a more open movement, guiding the racket's head in that direction, but you should finish it just like the other movement. I guess it's hard to explain. Try watching a good player serving/coach.
