TakeNGive 11k: If I understand correctly, in Japanese Counting (territory scoring), neither Black nor White gets any points from the seki; but with Chinese Counting (area scoring), Black gets 2 points from the stones living in seki, while White gets 12 points from this seki (10 points from the stones living in seki plus 2 points from the eyes a and b). Right?
unkx80: You are right.}
Hmm. I think that saying that he gets '10 points from the stones in the seki' can be misunderstood. With area scoring all alive stones on the board (+ territory) count as points. Stones involved in a seki are alive and thus count as points. That is not because they're in a seki, but because they are alive. In practice, under area scoring, there are extra no points from a 'balanced' (same number of eyes/liberties) seki either - if Black has 10 stones in the group and White only 2 then White has 8 stones (=points) somewhere else on the goban.

MikeTerry: Another point - under the area counting rules I know of (Chinese and Ing rules) Dame points surrounded by both players are shared equally rather than ignored. So ignoring the outside stones in the diagram above, Black actually has 3 points, and White has 13 points. Of course, counting the shared points does not alter the difference in Black and White scores, and so has no effect on the game result.
