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.
