I've come to realise that there are secret shots in this game a while ago. I know you can do Banana shots, Short slices and Slice Lobs.
There is just one shot that I've seen done that I can't quite figure out how to do. I only see CPU's use it when they are on either Masterful or Incredible difficulty.
It's when the ball is hit and it kinda has outward side-spin, it's hard to describe it so I'll put a link to show a demonstration

Roger also has that side-spin when he hits inside-out shots with his forehand
Is this even possible to do as a human player? It's been bugging me so much lately not knowing
