Unfortunately I found out that ********** was using a bot to play his moves in Backgammon and Nackgammon games. As Fencer understandably won't to act on it until it has been confirmed by other users, and as ********** has mainly played private games, I appeal to his recent opponents that are acquainted with the usage of GNU backgammon (the best free program and the one that ********** uses). Here are the steps to reproduce :

1) Choose a recent finished private match that you played with ********** .

2) Click "download MAT code" at the top right of the game screen and save the file to your disk.

3) Start GNU backgammon.

4) Go to Settings / Analysis and choose the "Expert" level for both checker play and cube decisions.

5) Click the Import button, choose the .mat format and your saved .mat file.

6) Go to Analyse / Analyse match. GNU will analyse all played moves.

7) Go to Analyze / Game statistics - and not match statistics, because there is a bug in the BK import format that swaps players every two games. Browse the games. In each of them, I bet that you will see one player with a human error rate (you) and one with an error rate of virtually nil ( ********** ).

Before jumping to the logical conclusion, you should know that the world's best players have an "Equivalent Snowie error rate" around -2 on a good day. You can check that for yourself by downloading world-class matches from here : http://www.hardyhuebener.de/engl/matches.html

On a last note, "expert" is a lowish standard in GNU backgammon, and I have seen ********** play a move that was also played by the expert level, but discarded as a big blunder by the "world class" level (which analyses 2-ply instead of 0-ply).

Thanks by advance for your input !
