disguising spin

hi alois and jeff,

how do i disguise spin to get a loose return from my opponent that i can kill/smash? i use the pendulum swing demonstrated in serving secrets revealed but cant seem to diguise the spin...any ideas.?

thanks 

Hi Shripathi,

Disguising the serve takes a lot of time.

The idea is to get the start position of all your variations the same.  Then try to make on subtle changes as you swing through to get the different spins.  The more similar the swings look, the better your serve will be.

It may be a good idea to video your serves and see what they look like.  See how early in your swing you can tell what type of serve you are doing.  You will pick up the differences in them and see what your opponent is seeing.
