LISTENER QUESTIONS Kenny Koala Bear on Twitter: What can be done to address the distinct prize money differences in WTA and ATP tournaments? The difference between Stuttgart and Barcelona was huge! Carmen on email: With the clay season in full swing, I'd like to learn more about how chair umpires determine which specific mark on the court was made by the ball when a player challenges a call.

I’m only 29 so don’t have much to compare to though! What do you think, are drop shots used more now than they used to be? Also, how much can you coach when to play a drop shot and how much is down to instinct?
