The Backgammon Encyclopedia - Vol 1/Cube Reference Positions
Players have understood for some time that the best way to learn cube strategy was through the use of reference positions: key positions that recur (with small variations) over and over, whose equities can be memorized and understood. By comparing your actual position to a known reference position, you can make a very reasonable guess as to the correct cube action for the position in front of you. Having an adequate library of reference positions at your fingertips is one of the keys to backgammon mastery.
In Volume 1 of the Backgammon Encyclopedia, Kit Woolsey has collected the key cube reference position for a variety of standard position types, including blitzes, races, primes, backgames, containment games, ace-point games, and holding games. By careful study of the more than 200 reference positions in this book, you'll be able to time your doubles and takes much more accurately. All positions are accompanied by tables of Snowie 3 rollouts conducted at 3-ply for extra accuracy.
