How to do a counter smash

Hi there, I was wondering how I could perform a counter smash on a 'No Spin' smash. I've seen many players do this so any advice would help thank you.

Hi Hare,

This is a very difficult thing to do.  I think first think about watching the ball carefully as they smash so that you get the best chance to see it.  Then try to contact the ball at it's highest point of its trajectory and hit the ball flat back.
