Pendulum serves

I know that if a right handed player uses a sidespin or topspin pendulum serve it usually curves to the right but how can a right handed player make it to go left instead.

Hi Martin,

They can do the reverse Pendulum serve.  You do this by brushing on the opposite side of the ball.

Start with the forehand side of your bat facing in towards you and then flick your wrist through brushing the right hand side of the ball.  Finish with your bat pointing at the far net post.
