On MSO the position below is said to score as W+0.5 (57 - 53 +4.5 ) under old Korean rules. Let's check:
That's
-11 11 11 -5 -7 14 3 -8 -7 5 -15 13 --------------------- 57 - 53
With 4.5 komi, White won with half a point.
This in mind, Bill took Black's side. See his analysis.
Robert Pauli: How about putting your analysis here, Bill? But
Bill: Very nice. It has been a long time, but I think I looked at that. If so, I missed the fact that Black need not play the atari, which gives White two threats for one.
A reanalysis might show that Black can win by more.
Bill: Big booboo. White should interpolate 32-33 first, though. I haven't taken the time to really check, but I think that occurred in the write-up, and that the result is the same.
Bill Fraser pointed that out to me around 3 years ago. I would have posted a correction, but the MSO site was dormant by that time.
axd: in the initial end position, there are 4 more W stones than B; assuming W has 4 more prisoners than B, and komi=4.5 gives Kor:W+0.5 Chin:B+0.5, Jap:B+1.5. It would be interesting to present a game where the score shows a substantial difference as compared to Chin/Jap. scoring.
psygo?: Where can I find the whole sgf file for this sunjang game (and maybe others)?
