Product Information

A game plan in which the chief objective is to enter as rapidly as possible into a pure race; a running game. To hit an opposing blot sitting on the front edge of a partial prime to keep the blot from escaping. Also, using a BB prevents situations in which you need to ask your opponent to roll again because you think the roll has been invalid. In fact, the use of BB in tournaments is becoming either a preference or a requirement, and in some cases imposed by the tournament director. A hit designed to forestall the opponent by depriving him of half a roll when the opponent threatens to hit a blot or make an important point, or needs to consolidate a disorganized position. A position of known value that serves as a standard by which other similar positions may be measured or judged. See: Cube Reference Position.

To take advantage of the opponent's requirement to make a move. You leave him a position in which the only move he can make hurts his position. Often this means he is forced to break a valuable defensive point (2) earlier than he would like. A play that leaves no blots, or a play that leaves blots only in positions where the opponent is unlikely to hit. Compare: Bold Play. x where TP is the cubeless equity of your take point, L is the average value of your cubeless losses (e.g., −1, if you can't lose a gammon), W is the average value of your cubeless wins (e.g., +1 if you can't win a gammon), and x is a number between 0 and 1 (typically 0.55 to 0.8) that measures cube efficiency. See Janowski's article, Take-Points in Money Games. The difference in your equity before a roll and after it, or the difference between rolling poorly and rolling well.A range of values that contain, with a certain probability, a rollout's convergence value. For example, with a 95%-confidence interval, there is only a 5% chance that performing the same rollout an infinite number of times will yield a result outside the interval. See post by Stig Eide. Whenever a player accepts doubled stakes, the cube is placed on their side of the board with the corresponding power of two facing upward, to indicate that the right to redouble, which is to offer to continue doubling the stakes, belongs exclusively to that player. [44] [45] If the opponent drops the doubled stakes, they lose the game at the current value of the doubling cube. For instance, if the cube showed the number 2 and a player wanted to redouble the stakes to put it at 4, the opponent choosing to drop the redouble would lose two, or twice the original stake. Because you must be "bananas" to try it. Attributed to Kent Goulding."] To hit loose by breaking a point in your home board, thereby leaving two blots. A player cannot take an opponent's piece until at least one of his pieces has been moved into his inner (bearing) table.

The second-last round of an elimination tournament; the one that determines the two players who advance to the finals. One of the sections in a tournament into which players are divided according to their ability and experience. For example, a tournament might have a novice division, an intermediate division, and an open division. Each turn, a player rolls two dice. The numbers shown decide how far the player may move their pieces. An offer made by one player to his opponent during the course of the game (on that player's turn, but before he has rolled the dice) to continue the game at twice the current stakes. The opponent may refuse the double, in which case he resigns the game and loses the current (undoubled) stakes. Otherwise, he must accept the double and the game continues at double the previous stakes. A player who accepts a double becomes owner of the cube and only he may make the next double in the same game. The value of a position to one of the players. Equity is the sum of the values of the possible outcomes from a given position with each value multiplied by its probability of occurrence. It is the same as the fair settlement value of the position. Your equity is the negative of your opponent's equity. See post by Gary Wong. Equity comes in different flavors. See: Cubeless Equity, Cubeful Equity, Match Equity, and EMG Equity.

That means you cannot make a move with one dice and then say Pass, A particular roll of the dice which could hit an enemy blot. When counting shots, you count each doubles roll once and each mixed roll twice to get a total out of 36. Hypergammon is a game in which players have only three counters on the board, starting with one each on the 24, 23 and 22 points. With the aid of a computer this game was solved by Hugh Sconyers around 1994, meaning that exact equities for all cube positions are available for all 32 million possible positions. [54] [55]

The value of cube ownership to the player being offered a double; the additional equity that comes from being the only player who may redouble. The number of plies played in each trial of a truncated rollout. A rollout that is truncated after 10 plies has a 10-ply horizon. A game in which the doubling cube has reached a high enough level that a win by either player also wins the match. A position with a flexible game plan; a game where there is more than one reasonable strategy for winning, such as racing, priming, or blitzing (1).A measure of playing performance equal to the total number of points (4) won (or lost) divided by the number of games played.

A guideline for cube handling in pure race positions. If you add 10% to your pip count, you should double if the result is not more than two pips greater than the opponent's count, and you should redouble if the result is not more than one pip greater. Your opponent should accept the double if your count plus 10% is no more than two pips less than his count. Sometimes spelled "lovers' leap".] An opening roll of 6-5 played from the opponent's one-point to the player's mid-point.A player of some experience who has begun to hone his skills; the level of play between novice and advanced.
