A competitor in a tournament whose position in the draw is predetermined to ensure that he will not meet other seeded players in the early rounds of an elimination event. See this thread. By analogy to market loser.] A sequence of two rolls (one for you and one for your opponent) which takes a game from a position in which your opponent would refuse a double to a position in which your opponent would accept a double. The dimensions of a board when opened, for a tournament game, should be at a minimum of 44cm by 55cm to a maximum of 66cm by 88cm. [43] Setup [ edit ]

CF = CL*(1 - x) + CE*x where CF is cubeful equity, CL is cubeless equity, CE is cubeful equity assuming all doubles are perfectly efficient, and x is a number between 0 and 1 that measures the cube efficiency. Typical values for x range from 0.55 to 0.8. See also: Janowski's Takepoint Formula. In our doubling cube collection, we offer a range of sizes to choose from, including the largest option which measures 1-3/16 inches. Our doubling cubes are crafted from various materials, such as wood and acrylic, and are available in a variety of finishes to suit your preferences.

The expected loss in pips (2) from dice rolls not fully utilized during bearoff. Wastage is calculated as W = R x 49/6 − PC, where R is the expected (average) number rolls required to bear off, and PC is the pip count of the position. Wastage is the difference between the usual pip count and the effective pip count. See post by David Montgomery. A recorded match with added analysis and commentary. Example:The annotated match between Kit Woolsey and Jeremy Bagai. Which player has the right to make the next double. At the start of the game, the cube is in the middle and either player may double. After one player accepts another's double, he owns the cube, and only that player may make the next double. Overage Points (4) won in excess of those needed to win a match. For example, if you win a game worth 4 points in a match in which you are 2 points away from winning, the surplus 2 points are overage. If after starting to bear off, a player's piece is captured, that piece must re-enter at the other side of the board and bearing off cannot re-start until all pieces are once again residing in the inner table.

A numeric value that uniquely determines the sequence of dice rolls produced by a random number generator. A rule that says that an illegal play should be pointed out by the opponent if he notices it, and such play corrected before the game continues. This is different from the usual rule giving the opponent the option of allowing an illegal play to stand. See post by Marc Gray. special cases (3-2, 2-2, 1-1); where 3-2 is a version of 2a with a "ba" added for phonetic reasons, 2-2 is Persian: دوباره for "twice" or two-times-two, and 1-1 is a hybrid Turkish-Persian where hep is Turkish for "altogether". [86] An optional rule for chouette play which says when only one player on the team accepts the box's initial double that player is obliged to accept an extra 2-cube from any other team member that wishes to pay him one point (4). See posts by Daniel Murphy and Toni Wuersch.

You roll a number which corresponds exactly to how far the piece would have to travel to exit the board. One of the standout features of our solid dice is their rounded corners. This design ensures that each roll of the dice is random, providing equal probability in rolling and fair gameplay. With our solid dice, you can rest assured that each roll is based on chance alone, making for a more enjoyable and exciting gaming experience. To intentionally allow a blot to be hit for the purpose of gaining time to preserve other valuable points (2). A tournament for players who lose in the first rounds of the consolation flight or later rounds in the main flight. A player cannot take an opponent's piece until at least one of his pieces has been moved into his inner (bearing) table.The defensive point (2) you control when playing a holding game, usually the opponent's four-point, five-point, or bar-point.

Proposed by Danny Kleinman.] A guideline for cube handling in pure race positions. Compute K = (D+4)*(D+4) / (S-4), where D is the player's pip count minus the opponent's count, and S is the sum of the pip counts. Kleinman says a player should make an initial double if K > 0.44, or redouble if K > 0.61, and the opponent should accept a double or redouble if K < 1.2. See post by: Øystein Johansen. Captured pieces are re-entered on the furthest point from the player's inner table. A throw of 1 allows the piece to move from the bar to point one of the opponent's inner table. A throw of 5 allows the piece to enter at point 5 of the opponent's inner table. Named after Tim Holland, who proposed the rule.] An optional rule in match play that was popular in the 1980's but is now rarely used. After the Crawford game a player may not double until at least two rolls have been played by each side. See post by Kit Woolsey. 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.To advance a runner so it directly bears on an opponent's blot, forcing the opponent to cover the blot, move it, or risk it being hit. To leave a position in which a particular number will play comfortably next turn so you will not be forced you to destroy your position if you roll that number. Typically, you save a number to avoid having to leave a shot or break a valuable point. Compare: Kill a Number. a b c Austin, Roland G (1934). "Zeno's Game of τάβλη".

The rules of match play say that the doubling cube may not be used during the Crawford game. See: Crawford Rule. A game popular in Bulgaria in which players pin opposing blots rather than hit them.
