Squash is played between two players on a squash court with a squash ball. Each player should have non-marking shoes and a squash racket.
Points can be scored by either player in a rally. When a player fails to serve or return the ball in accordance with the rules, his opponent wins the point. When a player wins a point, they become the Server and add one to their score.
Games are scored to 11 points. If the score in a game is tied at 10-10 (10-all), a player must win by two points (e.g. 12-10, 15-13, etc.) Matches are usually played to a best of 3 or 5 games.
The right to serve in the first game is decided by the spin of a racket. The Server continues to serve in each rally until he loses the point. The opponent will then become the Server.
At the Server’s first serve, he will have the choice of serving from either service box. Every serve thereafter will alternate sides for as long as they remain the Server.
The ball must be served onto the front wall, between the service line and the out-line. It must land in the quarter of the court opposite to the Server’s box.
A service is a fault if:
The Server does not have one whole foot in contact with the floor within the service box. (Foot-fault)
The Server fails to strike the ball after releasing the ball, and before it touches any other surface of the court or clothes of the player.
The ball does not land between the service line and out-line on the front wall or touches any part of the wall above the out-line.
The ball does not land within the quarter opposite to the Server’s box.
After a good service, players take turns to return the ball until one player fails to make a good return. A ball is considered to be good only if it has been returned before it bounces twice on the floor and touches the front wall (above the tin and below the out-line) before touching the floor again.
A let may be allowed if:
There is a safety concern where one player stops due to fear of hitting his opponent
The striker occurs interference by his opponent en route to hitting the ball, and he would have otherwise made a good return
The referee is unable to decide on an appeal of an out or not-up ball
A let shall be allowed if:
The ball breaks during play
The receiver is not ready for the service and makes no attempt to return it
A player must make every effort to get out of his opponent’s way to give his opponent freedom to play the ball. A player should not crowd, interfere with or obstruct the opponent on his way to play the ball.
A player will be awarded a stroke if:
The striker occurs interference by his opponent en route to hitting the ball, and he would have otherwise been able to execute a winning shot
The ball in play touches the opponent (or anything carried or worn by him) while on the way to the front wall
The opponent drops his racket or distracts his opponent in any other way where the referee considers the occurrence to have cost the player to lose the point
