rallies, which may feature playing the ball off other obstacles. When playing these rules a judgmental element is included for poor sportsmanship. If a player en devours to play repeated shots in order to set up winning shot, such as repeated hits off the wall whilst positioning themselves in a place to slam the ball in an unreturnable manner, then poor sportsmanship is called and this player forfeits the point. Surfaces Due to the nature of courts being dependent on available conditions, and funding problems preventing any official table squash courts to be purpose built, there are often different features around the court that may influence play. The rules regarding these features should be agreed before commencing play. For example there may be additional walls around the table or a roof in position, typically these surfaces can be played off without a point ending as long as the correct sequence of playing off the scoring wall (the wall perpendicular to the net than the table is placed against) and the opponents side of the net is completed also. If the scoring wall has obstacles on it decision should be made before commencing play whether striking these should constitute a foul. Under official rules all attempts to minimize such obstacles should be made but striking them should not constitute a foul. Non regulation tables The game can be played on any available rectangular table on which a net may be affixed, gameplay can be altered by using different size tables which alter the available space in which to hit the ball. Alternatively a two piece table can be folded into a right angle. With the net secured to the edge of the horizontal surface and allowing a small gap between the vertical surface. The game then commences making use of the tables centre line as the deliniator for points and serves and continues using the regular table squash rules.
