Basic Squash Rules

Once the ball has been struck, it is the responsibility of the striker to clear the way for the opponent to make a return.
If there is interference in the opponent reaching the ball, the players should play the point again (this is called playing a LET).
If your opponent is in the way of you making a return or is in danger of being hit in the process, a LET should be played.
Both the striker and the opponent should make every effort to clear the ball or to get to it if a LET is to be played.
If the player hits the ball back to themselves and hits them or goes very close to them, a STROKE is awarded to the opponent, winning the rally for them.
