If a player is unable to return to the tournament, all his games are nullified as they would be in disqualification. If a player is disqualified in a game, he loses that game and gets no points. The opponent is credited with a game won and is given the number of points he would have scored had he won the game. Tournament continues as though one less player started when tournament opened. If, for reasons beyond his control, a player cannot start a game, he must notify the tournament manager in time to allow for a substitute player, or for another pair of players.
All tournament contestants are subject to immediate call if a substitute is necessary.
If a referee is officiating and considers a player to be taking an abnormal amount of time between strokes or in determining the choice of shots with the intention of upsetting his opponent, the referee shall warn the player that he runs the risk of disqualification if he pursues these tactics. Continued disregard of the warning shall be proper grounds to disqualify the player. If no referee is officiating, the tournament manager shall have the right to invoke this rule. Deliberate safeties are not allowed. If played, the incoming player may accept balls as they are, or set up a break shot.
