One of the most frustrating things a player can do it to hit a great
shot, or series of shots, and still lose the point.
Many times this frustration comes from a lack of anticipation and
failure to react to your own shot. Let me give you an example.
Your big weapon is your forehand and you've just hit deep to your
opponents backhand. It's obvious that your opponent will
be lucky if he/she can get the ball back. At this point, you should be
prepared to move in, anticipating his/ her weak attempt at a shot. (This
scenario assumes your opponent is too far out of position to hit an effective
defensive lob.) By moving in, if his/her shot does make it over, you will
be in position to hit to the open court with your opponent still off the
court.
Now if you don't react and move in and you let the ball come back to
you, your opponent might have enough time to recover back to the middle of
the court.
The next time you play a match, try to react to your own shot earlier.
You might just find that you have more open court, more time to hit to that
court, and more wins!
