How to Do Two Spins on serve

I now know how to serve a heavy sidespin, backspin and topspin but I want to know how to serve a backspin with sidespin or topspin with sidespin because If i serve backspin my opponent can easily control the ball but if I have some sidespin on it I can predict the ball depending on the racket angle.

I usually serve with a pendulum serve and a backhand serve.  I also do some tomahawk serve and windshield wiper serve to surpirse my opponent but I want to really know how to serve two spins.

Hi Raoul,

If you want to get both spin then it is a matter of getting a particular contact on the ball.

So for backspin and sidespin you need to come down and across the ball to get that spin.

Take a look at the tutorial on Learning To Spin.  What you would be aiming to do is get the ball to come back to the net and move to the sides lightly to show that you are getting the two spin.  By looking at getting different paths other than straight back towards you you are regenerating two spins.
