Avoiding Powerful topspin

First of all congratulation for your 60,000 subcribers

I play on dinner time at my school and the guy that I play with has a really powerful forehand topspin. I tried to place the ball in all the spots that you suggest but it is not working. I play with long pimples on my backhand.

Hi Jeremy,

Thanks for pointing out we now have 60000 subscribers.  I had missed the milestone.

Have you focused on keeping the ball lower as well?  This could help.  Also make sure you are using variation of both spin and speed of your shots to keep him off balance.
