The most complete glossary of backgammon terms
An immediate redouble by a player who just accepted a double. A player who beavers turns the cube up one level and retains possession of the cube. See: Beavers.
An optional rule in money play: If both players throw the same number on the first roll of a game, the stakes are doubled. The doubling cube is turned to 2 and stays in the middle. Players usually agree to limit the number of automatic doubles to one per game.
