Territory-style scoring?

[snan]

We mostly play territory style scoring (like in Japanese rules). Is that in the pipeline?

[hauensteina]

Using Japanese rules would require knowing the number of prisoners. However, the number of prisoners cannot be determined from a photo.

There are two realistic cases where the rules matter:

(1) A Black 0.5 win by Chinese rules will turn into a White win by Japanese rules if Black made the last move.

(2) In a Handicap game, by Japanese rules the handicap stones turn into komi in White's favor. Chinese rules are harder for White in handicap games.

To address (2), KifuCam first counts Chinese, then adds the number of handicap stones to the White score to arrive at the Japanese result.

Hope this helps,

Andreas

Actually, this is only true if Japanese rules with 6.5 komi are used. It does not matter with 5.5 or 7.5 komi.

Great point; my main concern was dame and final ko. As far as prisoner's are concerned, the Chinese system is fine, it gives the same delta between the player as the japanese system. It's only the last couple of moves, passing etc, endgame that can be a li'l different 😱
