Cover Up

Never advertise your weaknesses.  If you miss a shot walk away with dignity, with your head high.

There is one tactic which I have seen often work.

Play the court favoring your weaker side, make it more difficult to place the ball there.

Make such spaces look smaller and your better shots a more tempting ground.

Use that on your return of serve as well.  Tempt the opponent, and be ready to cover ground.
