A game in which one player bears off all of his checkers while his opponent still has one or more checkers on the bar or in the winner's home board, counting for triple a normal game.
Bar
The area where blots are placed after being hit, usually, a raised divider between the home boards and outer boards.
Bar point
Either of the two points in the outer board adjacent to the bar; the 7-point or the 18-point.
Bear off
To remove a checker from the home board by rolling a number that equals or exceeds the point on which the checker resides.
One of the 15 playing pieces allotted to each player.
Cubeless Equity
The value of a position ignoring the use of the doubling cube. This is a value between -3 and +3 that takes into account the probabilities of either side winning a single game, winning a double game or winning a triple game. If at a given point in the game neither party can make a gammon, the cubeless equity of a player simply is the probability of him/her winning the game, minus the probability of the opponent winning the game.
To move onto a point occupied by an opposing blot, and move the opposing checker to the bar.
Home board
The portion of the board containing points 1-6. The checkers need to move here before they can be borne off. It is also the part of the board where the opponent's checkers are re-entered from the bar.
A match score expressed in terms of the number of points needed by both sides to win the match. For instance, '2-away/4-away' (or: -2/-4) could indicate the state of seven-point match in which one party has gained five points and the other side three points.
Notation
In backgammon the common way of describing the movement of checkers involves numbering the points around the board from 24 to 1 such that the numbers diminish when the checkers move towards the home board. This implies that a reverse numbering applies when the opponent is on roll (with the 24-point now referred to as the 1-point, etc.). A move of a single checker is indicated by the start and the end number separated by a slash. If a move results in a checker being hit, this is indicated by adding an asterisk to the number on which a checker was hit.
One of the markings on the face of a die, corresponding to a movement of one point.
Pip count
The total number of remaining pips needed to bear off all checkers.
Point
One of the twenty-four narrow triangles on the backgammon board where the players' checkers sit, or the value of a single game of backgammon before accounting for the doubling cube, or a gammon or backgammon.
