With every point you should play with controlled aggression. What this means is not trying to attack every single shot, and not passively just trying to get the ball in the court. There is a three step progression that was taught to me as ‘control, hurt, finish’.
First you want to gain control of the point, either by hitting a deep ball with heavy topspin, a well-placed shot that gets your opponent out of position, or anything that makes them off-balance.
Next, you want to hurt your opponent a bit. They’re only moderately out of position and off-balance. You want to make them even more off-balance, so hit another slightly more aggressive shot to make them run across the court in whatever direction. They’ll probably pop up a weak return.
Finally, you finish the point either with a volley at the net, or a well placed put-away shot.
