"I need to play against better players to improve my game." I hear it in lessons all the time. And there is some truth to it. Players that have skills better than you can push you physically in ways that some other practice partners can't. In addition, you will see shots that they hit that you might consider developing or improving. One of the most important aspects of only playing better players is that there is less pressure to win or more importantly, no pressure to lose. Therefore the match lacks somewhat in helping your mental game.

It is also important to play opponents that may not be as good as you. You will probably have the comfort of trying shots that are new to you. You can always work on a new game plan or strategy and play to a weaker player's strengths to get added practice. Weaker players may also raise the level of their game since they now have nothing to lose.

Supplementing your practice with opponent's that you are competitive with will also greatly add to your game. Playing in matches that push you to your limit both physically and mentally puts stress on you that you will need to control in tournament match situations. Learning to control that stress and recover from it will make you a stronger player.

It is very important to play against players of all abilities. Each type of player can give you the opportunity to work on a different aspect of your game. Try to play matches with players of a variety of abilities. If you can't stand to play an aggressive player, add a serve and volley opponent to your routine. Hate to play the lobber? You should practice against one a little more so that you can be prepared in the tournament. Remember to practice your weaknesses more than your strengths and vary your type of match play and you will find your game growing.
