Hi: I just joined this forum and this forum is great. I have one question from the experts on this forum. When I am playing doubles against this one particular very good, tall and aggressive player, I am hesitant to serve low thinking that I will get smash to the body or my serve off the net will be too high. So I always end up serving high to him. So there is no surprise when I my serve to him. He knows that I am going to serve high to him and is ready for it. I am ok with other good players. I can mix up my serves to keep them off balance. I have asked this guy how I can improve my play and serve against him (he was a coach for a national team and is pretty good about answering anyone's questions and suggestions for improvment) and he said I just need to get over this and play through it. Any suggestions from experts on this forum?
