Doh, forget all those questions. The answer is trivial and I didn't have enough caffeine. Once your opponent has taken one man off the board you can no longer gammon him. You can only score a gammon or backgammon IF your opponent has NO men off. Since he already has one off (5 in this case) it is not possible for you to win a gammon. There are a nice set of rules at http://www.bkgm.com/rules.html . The rule there is as follows: At the end of the game, if the losing player has borne off at least one checker, he loses only the value showing on the doubling cube (one point, if there have been no doubles). However, if the loser has /not/ borne off any of his checkers, he is gammoned <http://www.bkgm.com/gloss/lookup.cgi?gammon>and loses /twice/ the value of the doubling cube. Or, worse, if the loser has not borne off any of his checkers and still has a checker on the bar or in the winner's home board, he is backgammoned <http://www.bkgm.com/gloss/lookup.cgi?backgammon> and loses /three times/ the value of the doubling cube Sorry, -- Michael Petch GNU Backgammon Maintainer / Developer OpenPGP FingerPrint=D81C 6A0D 987E 7DA5 3219 6715 466A 2ACE 5CAE 3304 _______________________________________________ Bug-gnubg mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-gnubg
