You must test with Gnu-Go level 16.. This is according to Stefan Mertin by far the best mode. But it takes sometimes quite a long time till Gnu-Go makes it move. In your experiments Gun-Go played very fast. You played fast Blitz and Gnu-Go had a big time handicap (besides Handtalk, which plays Ultra-Blitz).

Subject: [computer-go] Gnugo vs commercial programs


I tested Gnugo against some commercial programs.
