The Jacoby Rule

The Jacoby rule allows gammons and backgammons to count for their respective double and triple values only if there has been at least one use of the doubling cube in the game (not including automatic doubles). This encourages a player with a large lead in a game to double, possibly ending the game, rather than to see the game out to its conclusion in hopes of a gammon or backgammon. The Jacoby Rule is widely used in money play but is not used in match play.
