I've got a 9x9 game against fuego that I thought was a win for me (W+0.5) but Kaya seems to have scored it one point different (B+0.5). Should be Japanese scoring, according to the game info.



My count was ...

White:
Komi - 6.5
Territory - 25
Prisoners - 1
Total = 32.5

Black:
Territory - 29
Prisoners - 3
Total = 32

Did it not actually count Black's last move (which I don't think was necessary and gave me the win; bot logic)?

I think w actually has 24 points of territory
edit: nvm can't count.

Yeah, my second time counting I got the same as you did.

When it comes to scoring with bots, we dont actually do it ourselves: the bot engine itself does the scoring.
I've seen things like this happen from time to time. Unfortunately I never got around setting up fuego on my pc and manually checking what fuego scores on these specific cases.

No worries. I figured if you guys were doing the scoring that you'd want to know.Good to know it's a bot issue.

The bot must be doing Chinese counting, despite the apparent game setting, which is a 0.5 point win for black. However, komi in Chinese scoring is normally 7.5 , not 6.5 (there are good reasons for komi being odd numbers in Chinese counting, which I can't recall offhand), which would help account for this half point inconsistency.

fuego just kind of seems to do whatever it wants to in terms of score. I once had it just mark the whole 19x19 board dead, take his 6.5 points and leave the game.

As long as you don't have a seki with an odd number of dame (a rare occurance), an odd number of total points are claimed at the end of the game (for 19x19, usually it's 361, every point on the board).

The narrowest margin of victory is 1 (181 to 180). The next closest would involve you getting an extra point that your opponent doesn't get -- a three point victory (182 to 179). Next closest to that is a five point victory (183 to 178), and so on. In the vast majority of games, a 2.5 point komi will help you no more than a 1.5 point komi because you either lose by 1 or lose by 3. Same is true for all even komi. In territory scoring this isn't the case, because you can reduce one player's score without affecting the other player's score (a play in your own territory, for instance).

Nice, so the bot can cheat easily then
