Ratings Pool
The people who participate in a ratings system.
Ratings System
A method of assigning ratings to players based on their performance in such a way that players with greater ability will, over time, tend to have higher ratings.
Raw Take Point
The minimum game winning chances you need to accept a double if you assume no gammons and no further cube action. The raw take point can be derived from a match equity table and depends only on the score of the match, not on the position. See post by Timothy Chow. Compare: Take point.
Recirculate
To intentionally allow a blot to be hit for the purpose of gaining time to preserve other valuable points (2).
Recube Vigorish (Vig)
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.
Redouble
A double other than the first double of a game. Only the player who last accepted a double may redouble. Compare: Initial Double.
Reference 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.
Refuse a Double
To resign the game at the current stakes after the opponent offers a double rather than continue play at twice the stakes. Compare: Accept a Double.
Resign
To accept defeat. Resignation is a form of settlement; when you resign you must specify whether you are resigning a single game, a gammon, or a backgammon (2), and the opponent must agree. Resigning is not allowed in tournament play before contact is broken.
Return Shot
A chance to hit back after being hit yourself.
Roll Out
To analyze a position by playing it out over and over again.
Rollout
An estimate of the equity of a position obtained through computer simulation. A rollout consists of numerous trials, the results of which are averaged together. See post by Gregg Cattanach. See also: Truncated Rollout, Cubeless Rollout, Cubeful Rollout, Random Error, and Systematic Error.
Roll-Over
A backgammon variant in which players have a once-per-game option of rerolling their own dice or asking for a reroll of the opponent's dice. See: How to Play Roll-Over.
