Hi Michael, Welcome to GNU Backgammon.
1) Dice are no respecter of ability! Even the best players can be defeated by bad rolls. Look at the Luck ratings to see how gnubg thinks it played out. Gnubg thinks it made no errors because it is using itself as the best judge of perfection! If you ask gnubg to play on Expert Level but analyse on World Class, you will start to see some errors creep into its game. 2) It depends on how beginnerish you are. According to the FIBS Rating Calculator at http://www.netadelica.com/bg/fibscalc.html a player with a 500 point Elo advantage should win a 13-point match about 89% of the time. This increases to 93% for a 21-pointer. You can play with the calculator yourself for other scenarios. (The experience fields should be set to at least 400 for both players.) I hope this helps.

Please forward it on to someone who could answer if it arrives at the wrong destination. gnubg describes my ability as a “beginner" - fair comment. However in a 13pt match, I beat gnubg 13-6. The analysis described gnubg’s ability as “supernatural" and indicated that it made no errors. I Have two queries in relation to this 1. How come gnubg lost? 2. How many points should a match be in order to ensure that gnubg wins every time against a beginner?
