Backgammon
A money-game position with the dice rolled. GNU Backgammon rollouts score every legal play by cubeless equity; the answer is the whole play, e.g. 24/18 13/11. See Methodology.
Fewer puzzles than the other models, so results are noisy.
Quality is the mean oracle score of the moves played, × 100. The best move scores 100; an illegal move or no move scores 0. Protocol boardbench-0.2.
