Think about the Friday night chouette where there was this tough choice between two move candidates. Which move was the best? Or what about that match score cube decision from the weekend tournament. Wouldn't it be nice to be able to set up the position in GNU Backgammon and ask for it's opinion? This is possible in GNU Backgammon, and it's one of the features that really can give you the answer to a lot of questions, and in that way give you a better understanding of the game.
