The player whose turn it is to serve shall serve the first point from the deuce court. After the first point, the players shall change ends, and the following two points shall be served by the opponents (the player of the opposing team due to serve next) starting from the ad court.
After this, each player/team shall serve alternately for two consecutive points (starting from the ad court); changing ends after every four points, until reaching 7 by a margin of 2 or continuing until earning a margin of 2 points to end the tiebreak game. Switch sides after points 1,5,9,13..…. and at the conclusion.
Principal Advantages to a Coman Tiebreaker:
• Fairness: by changing ends more frequently, the effects of the elements (sun, wind, etc.) are distributed more evenly between the two opponents. In doubles, the server will always serve from the same end of the court that he/she did during the set
• If the clock runs out before the end of the set, or if the court conditions are unplayable, the score will be posted as-is at the time the session ended.
• “Retiring Players”:
o If a pair “retires” (leaves the court) prior to the finish of the set for any reason other than the clock running out or unplayable conditions, the reported score will be as follows for that set:
o If the non-retirees are ahead, the score will stand as-is in the unfinished set. o If the retirees are ahead, the score for the unfinished set will not be entered into the computer.
o If the clock runs out before the end of the set, or if the court conditions are unplayable, the score will be posted as-is at the time the session ended.
