I'm a 3.5. Let's say I hit a good offensive shot deep to my opponent's (also a 3.5, so we're not worried about miracle shots here) backhand. I can see that he's barely going to get to the ball. He'll most likely hit a weak shot to the center of the court, but might get lucky and hit a lob deep. Also let's assume that I have enough time to get to any spot on the court by the time he gets to the ball. So where should I be doing my split step? Thanks.
