THE BEST OFFENSE IS A GOOD DEFENSE AGAINST CERTAIN OPPONENTS
Size up your opponents before you play your match and decide if you and your partner are steadier then your opponents.(do they make more unforced errors ) If you feel that you are steadier, then be patient and keep the ball in play with high percentage shots at their toes and down the middle of the court.Give your unsteady opponents a chance to lose. Do not over hit the ball using low percentage angle shots and try to over power your opponents.Wait patiently for a high percentage high put away shot and take advantage and put it away low to their backhand at 80 percent of your power. Use accurate and consistent shots. Give yourself more leeway for error.
If the other team is as steady as you and your partner, then you must be a little more aggressive. Use excellent shot selection and hit to high percentage places on the court.
Work the point and be patient.
Unforced errors will lose and evenly matched game.
