Don, Can the CGOS 19x19 starting rank be changed from 1200 to 1800? Almost all programs are now stronger than gnugo on 19x19. With the 1200 start it takes a very large number of games to climb over 2200, and by then the K value is so small that the top programs take a huge number of games to

For high handicap games taking black, giving white a big initial komi that decreases with time seems to help a lot. Otherwise at the first move, the program thinks it has over 80% win rate, and plays passively. This is not the way to win against a stronger player. David From:
