Countering Spin

Someone gives me a normal topspin ball and I do a topspin stroke

If someone gives me heavy topspin ball, does my topspin stroke change (speed, angle).

Hi,

If there is more topspin on the incoming stroke then you can turn the angle of your racket forward and also swing more forward.

Also take a look at the tutorial on Counter a Slow Spinny Topspin.
