LETS AND STROKES
If you think you are going to hit your opponent with the ball or the racket, DO NOT PLAY THE BALL, ask for a LET. If the ball could have gone to the front wall it is a STROKE (point or hand out). If the ball was going to the side wall first, a LET is played (play the point again). The same applies if you actually hit the ball and then your opponent, but for safety reasons it is better not to hit it!
If you TURN on the ball and hit your opponent it is considered a dangerous shot and you surrender a point or the serve. PLAY SAFE - Don't hit it.
If your opponent is seriously impeding your back swing or follow through, you receive a STROKE. If they are attempting to get out of your way then play a LET.
In most cases if you get hit by the ball or a racket, it is your own fault and the point goes to your opponent because you are impeding their shot.
REMEMBER: PLAY SAFE, give your opponent plenty of room to play the ball, and call a LET if you think you are going to hit them.
