Many people from different levels of play ask me about strategy. Surprisingly, it is essentially the same whether you're a 3.0 player or a 5.0 player.
Know the Basic Shot Strategy!
Serve deep and return deep
When both opponents are at the net and you are in the back court, hit a drop shot
Get to the kitchen quickly and keep your opponents back
Smash any high ball, preferably at an angle away from your opponents
Use the dink a lot
