Reply to this topic Return to forumThere 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.
Example: https://www.littlegolem.net/jsp/game/game.jsp?gid=1870170
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 it does show it as a loss for you:

…and as a lost game for your opponent too.
Weird.

Yes one is a win and one a loss, but both were won 100-0
This bug has been around for a few years:
