How much is an > ace-point game worth, assuming strong play by both sides? Hi, Over the board, I often put confidence into 'Liby's Rule': In a well timed acepoint game, the player have 17% chance of winning. This is a nice rule of thumb, even though I don't know how he derived it, nor which assumptions he used. For later acepoint game positions, check out Bob Wachtel's book: "In the Game Until the End: Winning in Ace-Point Endgames." This book is more like a derivation of best strategies for later acepoint games, when the player have only 3 or 4 remaining checkers to bear off. Each position is concluded with a best strategy stay or run of backgammon. -Øystein   Did you find the information in this article useful?           Do you have any comments you'd like to add?
