Hahn score
  • Crelo at 2017-08-28

    There is something strange about the Hahn games score. If one doesn’t win by 100% (resignation) and the board is counted, splitting the score percents, the game is marked as lost for both players, in the games list and in calculating the rating.

    I’m not familiar with the Hahn score system, but it does look strange: when I went to the game (the above weblink) I see: 

    White: 73 (area) + 24 (prisoners) + 6.5 (komi) = 103.5 points
    Black: 80 (area) + 9 (prisoners) = 89 points
    White win by 14.5 points. 

    And White getting “70” and Black getting “30”... but in your game record list < https://www.littlegolem.net/jsp/info/player_game_list.jsp?gtid=go19&plid=1935 > it does show it as a loss for you:

    Yes one is a win and one a loss, but both were won 100-0

    Indeed. The funny part is that Stefan lost it also:

    This bug has been around for a few years:
