What’s the best strategy when playing singles?

The best strategy is to hit the ball crosscourt , if you keep the ball crosscourt you’re hitting over the low part of the net and the long part of the court, by hitting down the line you hit the ball over the short part of the court and the highest part of the net. The rule is 80% crosscourt and 20% down the line and you’ll win 80% of your matches.
