I don't know how many high-rated players are reluctant, as I am, to join a single-game tournament against all comers.  Unfortunately, the BK rating system was not designed for backgammon and unfairly penalizes the higher rated player in a game between players with a large rating difference.  In order to permit higher rated players to enjoy a Triple Gammon tournament without worrying about ratings, I have created an unrated version.  All players are welcome.
