Strategy for shot selection. I use a phrase “hit to the brown”. Since most floors are brown and the open part of the court will be more “brown”. Hit there!
One exception to the rule would be fast players. They will head to the open court with ease so with them you hit against the brown. This causes the player to hit the brakes and head back the other way thus utilizing their speed against them.
(In tennis they call this hitting behind your opponent.)
When the player is behind you, you have an issue of course with this strategy. You really do not know where they are so wide angle shots(aiming for the side wall at the receiving line on the opposite side of the court) makes the court bigger. Shooting down the line also makes the court bigger but if your opponent guesses correctly you are in trouble. Therefore, you must mix these shots up and strive to be unpredictable.
Once you get the opponent guessing, you have the competitive edge!
