Fujitsu 4 Game 16
   

Event: 4th Fujitsu Cup [ext] on Jan van der Steen's web site
Round: Round 2, 8
Date: 1991-04-08
Place: Tokyo (Nihon Kiin), Japan
Black Player: Cho Hunhyun
Black Rank: 9 dan
White Player: O Rissei
White Rank: 9 dan

Source: 1992 Kido yearbook

[Diagram]
Diag.: Position at the end of the game record (move 242). Black to play.

Captured stones:
B: 1
W: 10

The top-left corner is a seki.

Can Black actually win the semeai in the top-right corner? It doesn't seem possible. Then White should win by 17.5, not 3.5!

Any idea?



Black is dead in the top right, and the score is W+3.5.

Black is dead, basically because in the semei, white has an eye and black doesn't.

To count the score:

White in bottom left: 34 points.

White in top right: 62 points.

White in top middle/left: 2 points.

White's prisoner: 1 points.

Komi: 5.5 points.

White's total: 104.5

Black's territory:

(What a pain, it is all in one lump, which makes it easy to lose count. I'll divide it artifically.)

Black territory, rows 7 and above: 25 points.

Territory from dead white stones in the Black territory: 30 points.

Other Black territory, rows 1 to 6: 36 points.

Black's prisoners: 10 points.

Black's total: 101

(I hope that was comprehensible, everyone has their own way of counting.)

Thanks for the help. I must have done something wrong to get such a big difference. Have to check again. Still, I don't understand why you count 2 points for White in the top left. It's a seki isn't it? The game was played in Tokyo so I suppose Japanese rules were in use.

Sorry, I wasn't clear. It is a seki in the top right corner, but there is another white group in the top left quater of the board, and I was referring to that.

--Tim Hunt


I see. Then White won by 3.5.
