Almost any time I'm 15 feet inside the baseline I'm going to hit the ball (regardless of which side the ball is on) to the ad court corner. That's normally a righty's backhand and I find hitting approach shots to their backhand works well for me.
Even if I'm mid court at the deuce side hitting a FH I'll hit DTL to their ad court corner (their backahand). If I'm mid court hitting an approach from the deuce sideline I'm gonna hit crosscourt to the ad corner (to their backhand).
