The Rules of Doubling Cube

What is with speed and doubling cube? Well, when we speak of it, a doubling cube adds strategy and dimension to backgammon. It is a dice with six marks and numbers 2, 4, 8, 16, 32, and 64. Initially, it faces up with the number 64, which is known as "centered on 1." Then, the opponent chooses to take the stakes or not by saying take or drop. If the player says, "take", the taker has the option to re-double with the cube on the taker's board.

Usually, there is no limit in re-doubling, as it can raise more than 64 stakes. In terms of money games, there are positions called beaver and raccoon. In "beaver" position, the player still has the cube in every doubling of the stake. On the other hand, "raccoon" occurs after the opponent beavers the cube; the player doubles the stakes again prior to another dice roll. For instance, 2 points is accepted by Black from White, Black then acquires the doubling cube to 2 points after accepting White's doubling. Black still has the cube while White raccoons the cube to 8 points. In this instance, if luck favors White, Black faces greater doubling of eight times.

To add more vigor to doubling cube, we can apply the Rules. Jacoby Rule is commonly used in money play, as this allow gammons and backgammons to count the respective double and triple values. Offer and acceptance of stakes signal the counting of values. This act makes significance in encouraging the lead player to double the value and ending the game.

Next rule is the Crawford, which is preferred among match plays. Doubling always come from the opponent that is the strategy to catch up. In order to continue the match, the weak player must win. Thereafter, the first player to reach one point score may choose neither to use the cube or not. Hence, both players now enter the Crawford game. Upon finishing the Crawford game, normal play resumes. Crawford games are common among tournament backgammon match games.

Subsequently, during the Crawford rule, Holland Rule may take effect. This is a regulation that if a player has already doubled twice, they cannot do so anymore. Holland Rule has been popular in the 1980s during tournament backgammon match games.

Finally, there is the "automatic double rule" or the Murphy Rule. This happens when both players have similar opening numbers. The doubling cube is incremented in each occasion but is available at the center of the board for each player. However, the limit on Murphy Rule for doubling should be agreed prior to match.
