Path: BigQuestionMark · Prev: BQM173 · Next: BQM175 DJ: Dear fellow Deshi's, these days I am once more reading (studying?) The 1971 Honinbo Tournament. The depth of the analysis (which makes it comprehensible even to a hopeless player like me), the quality of the players involved and, why not, the suspence James Davies has managed to put in the tale makes it one of the greatest ever go books in English (my VVHO).
I've been enjoying the At the end, Black is leading due to a mistake by Ishida in the early yose (at move 132).
After Black's 185 (
Now Davies says that Ishida had seen
leaving the reader to verify such a statement. I have tried both plays, a and b, but couldn't manage to contain White's loss to less than 8 points[2]. Weeeellll, Ishida is sure much more than five points stronger than me . . . ;-) Would anybody like to have a try? Remember, in those days komi was 4.5 . . . [3] What happened in the real game?
Seeing that he could not win, Ishida played 186 at
Instead, Rin played
Ishida therefore played
If now Rin connected at Just for history's sake, Ishida won the title 4-2 and became the youngest Honinbo ever, at 22. I'm not sure, but I think this record still holds, Cho U being just a few weeks older when he won the Honinbo from Kato last year. Incidentally, Cho U is a pupil of Rin . . . [1] Not a six-point gote? [2] Before or after komi? [3] . . . and - for those not wanting to count all stones on the board - three black and six white stones are in the lids. ;-)
DJ: Dear Robert, thanks a lot for all your editing! I will try to answer your questions...
Question n. 3
Wow, that's correct! Did you painstakingly count all the stones to guess how many were exchanged in the ko that gave birth to the lumpy five's (the
Question n. 2 Well, it was counting the komi in. But today I've found a sequence, starting with White's sente play, that brought her to a loss of 5.5 points only... pity that I have already forgotten it...
And now the most difficult, Question n. 1
At first sight I too counted the gote play as a 6-points one. In fact locally it is 6 points better for White with respect to the sequence where Black goes first. But if Black goes first he will do so in gote, and White has an annoying kikashi that forces Black to play twice inside his territory due to the damezumari of his lumpy five... IOW if Black goes first in the particular position of this game his territory is not as big as it looks. Let's see:
After Black goes first in the corner White plays
After White a and b Black will have to play only c: the black territory is now 9 points and White has gained 1 point at w, for a net result of 5 points.
Again, Black will have to play only c: the black territory is now 12 points and White has gained 1 point at w, for a net result of 2 points.
