It may sound silly, but i'm really unsure about this and actually made a bet on it: if you hit your opponent with the ball, then the ball comes back into your court, you still win the point, right? I mean, if someone hits the ball with ANYTHING else except from the raquet, he looses the point, right?
I asked a similar question once, if ii was match point up anecdote fame to the net, and the ball hit you on the head and killed you instantly but the ball trickled over the net, what would happen? Turns out you lose the point and forfeit through death.
