Today I was playing in the first round of a tournament, and once again under match conditions my forehand deserted me. It's the one stroke that no matter how hard I work it in practice, if I get tight it just goes south. I don't understand it. I can clobber it in practice. With the ball machine yesterday I was forcing myself to hit 20 in a row. Today in warmup I tried to hit with heavy topsin and fenced a couple. My confidence left and any time I went to hit a forehand I could feel myself tighten up and hit the ball into the net or 5 feet long. HELP!!!!!! Any tips on how to conquer this defect in my game. It's absolutely killing me in any comps I play in.
