A rule often used in money play (but never in match play) which says: A player who accepts a double may immediately redouble (beaver) without giving up possession of the cube.

Otherwise, he must accept the beaver and continue the game at quadruple the stakes prior to the double. See post by Sander van Rijnswou.
