Today, I was decided to make my lesson with my coach a full speed match, and we could work on what was costing me points, and in turn matches. So we play two sets, and I get hammered, 2 and 1. He overpowered my backhand very badly. He says the higher I get, the less effective a slice backhand gets. Realistically, I don't hit my slice repeatedly against anyone under 4.5, and I still don't use it much against the 4.5s who don't hit particularly hard, and hit with more topspin and placement, it's just the hard hitting players that end up drawing me into a chip fest. I'm curious from the better players how effective your slice is in match play and how much you use it. I have a good topspin backhand, but big hitters bring out the defensive, counterpunching tendencies in me. Any advice?
