Countering long pimples spin

Hi. I know that pimples change the spin of the ball(If I hit the ball with topspin, the opponent return the ball with backspin)but even if I open the racket to return the ball,the ball goes into the net.So,what can I do?

Hi Adrian,

The thing to do is open the angle more.  It is often difficult for players to get their heads around the amount of reverse effect the long pimples has.  Just keep experimenting with it until you get the feel on the angle that you need.
