What is a cut throat in tennis?

Not sure if this is the answer you're looking for, but I have played a form of Cutthroat Tennis many times. It requres 3 players, 1 person plays singles against the other 2 who play doubles. The singles player is the only one who serves and is played under the usual scoring system. The singles player has the entire (doubles) court to play to. But the doubles team plays into the singles court. If the singles player wins the game, he continues to serve until his serve is broken. It can be played to 6 games to win the set or to 10. If the doubles team breaks serve, the person in the ad court now becomes the singles player, the player in the deuce court plays ad and the 1st singles player now plays the deuce court. After every broken serve, it is rotated like that. First player to 6, or 10, wins.
