I play a guy who is the Jimmy Connors of our club. If he gets five revolutions from baseline to baseline, that's a heavy topspin shot for him. He also skims the net so closely that you can't believe he can continue to play with such small margins but he does, again and again and again, and often hits some incredibly sharp angles with his shots as well. When this guy is on, he's competitive with the best 60 year age groupers, but when he's off, he can litter the stats sheet with unforced errors.
Because he hits with such velocity and minimal spin, the ball trajectory is really flat so the ball comes off the court more like an underspin shot than a normal groundstroke. So other than being a foot or so further behind the baseline, that's how I think about hitting his shots and it works well. I don't have much of an issue putting significant topspin on the shots if they are at or above mid-shin level. Below that and I just take some speed off the shot to give more margin for error.
As for preventing him from hitting those shots, chest high or higher shots will usually get me a more tradition underspin shot, even off the forehand. Because he uses a straightforward eastern on both forehand and backhand, he has a tougher time coming over a high ball do he tends to hit either straight through it or with a slight downward trajectory, but both with less ball speed than if I put the ball in his slot, which is from knee to rib-cage height, with medium pace on the ball. The other thing I try to do is to put him deeper in the court with something high-bouncing, then come back at him with something shorter and off to the side. His lack of topspin capability means he can't hit these as hard so I have a decent chance of putting him on the defense with my next shot, but if I sit that short shot up, you give him a chance to hit a safe ball that I can't reach.
Both the high bouncing shots and hitting deep then short are really both attempts to get him out of rhythm, since low-margin-of-error players like that rely more than normal on feeling on time and in rhythm. Anything you can do to disrupt that will help.
