Ok, ok....I already know I cannot hit the topspin at chin height. I can hit it on the frame at chin height and put all kinds of funky stuff on it, but I don't know where it is goin.
Next question- I have watched the pros and their air-borne attack on groundies. Looks impressive and easy when they do it. So..When Federer hits that slice backhand, short real spinny forehand and the deep super flat forehand is this an attempt to keep the opponent from getting a chance to come off the ground returning his ball??
