Dosaku's Masterpiece - study
Posted: Tue Mar 06, 2012 12:21 am
Let's study a game... I've got a copy of a commented sgf that was adapted from Ohira Shuzo's book Appreciating Famous Games (translated by John Fairbairn)
I don't know the author of the abridged commentary. A record on gobase.org has the initials UC for the comments, but none of the variations.
The sgf record I have has many, if not most of the variations from the book, but none of the mentioned markup. Since it differed from the book slightly from time to time, I did my best to guess at the markup referred to in UC's comments.
The commentator says his comments and variations were adapted from commentaries by both Ohira Shuzo and Go Seigen. I only have Ohira's book (in English) as my original source, and am unfamiliar with Go Seigen's commentary on the game. (I don't yet see that he participated with Ohira on his book, though I haven't read it all yet, so I may have missed a notation).
Dosaku's Masterpiece was a 2 stone Castle game played between a member of the Yasui house, Shunchi and the head of the Honinbo house, Dosaku. It was played on the Japanese date of Tenna 3-XI-19 which most people read as Nov 19th 1683. But it should actually be read as Jan 5th 1684.
Naturally, GoGod has it listed as 1684-01-05, as does the Japanese site Momoyama. But most English language sources that I could find use the November date, including Ohira's Appreciating Famous Games that John Fairbairn translated.
And even worse, Googling for "Dosaku's Masterpiece" will find many YouTube and other sources (such as Baduk Legends) with also the wrong name of Dosaku's opponent -- likely both a misspelling and confusion of Yasui Shunchi with the then head of the Yasui house, Yasui Sanchi.
As John Fairbairn says elsewhere on this forum, there's no such player as "Yusui Sanchi"
Dosaku's Masterpiece
2 stones: Yasui Shunchi
White: Honinbo Dosaku
Date: 5th Jan 1684
277 moves.
Black wins by 1 point.
Commentary adapted from commentaries by Ohira Shuzo and Go Seigen.
The ogeima used to be the standard response to the kogeima kakari against hoshi. (a few too many Japanese terms for my taste 
)
is in the wrong direction
(variation for )
is an old style move. These days the extension to a is preferred.

feels oddly out of place. Works neater with 10 in place, but... Doesn't 
need to be answered? Isn't the hane-tiger mouth shape in that area just too strong (btw, why there are no coordinates in the board?
. What do you mean this joseki was unknown in the 17th century? 
Sure, they tenukied a lot, but that is not the same thing.
@ k3, but then White would probably play 5 at c6.
is a suspect move
if White hanes at a, pulling back at b is sufficient. 
This result is bad for Black. White can expose his weak points with a or b.
and/or sabaki possibilities with attaching to

is too small-scale and low
here, aiming at a follow-up at "a", and achieving better balance with "T"
is an aggressive move
)
at (a), 
at (b)) This exchange clearly favors White
is slightly dubious
Black gets a large moyo.
