The most complete glossary of backgammon terms
A game in match play where the doubling cube has reached a high-enough level that it represents sufficient points (4) for the leader to win the match; the trailer has nothing to lose by doubling at this point. This includes any post-Crawford game, where the trailing player should double at his first opportunity.
