1971 Honinbo Ch 8
Keywords: MiddleGame, Question, Books & Publications
This is the game between Ishida Yoshio (Black) and Fujisawa Shuko (White) in the 1971 Honinbo tournament.
After 100 moves, we reach the basic position shown. Note that there is an unsettled capturing race between the black and white groups with three liberties each in the lower left. This game has a commentary in the book The 1971 Honinbo Tournament. The commentary gives a number of variations from this point:
The commentary says clearly that this result is so good for White
that Black cannot allow it ('
Then it gives this variation. Once White has captured at
The commentary says that this diagram (where White connects his corner out in gote after a and b) is what ought to happen.
But in the actual game, Black plays this way (then fills a liberty at a and White lives with b). The commentary says that this is the same sort of result as variation 3, but five points better in the endgame for Black.
But what if White uses Can anyone explain this puzzle for me? Why didn't Shuko play 2? -- Matthew Woodcraft
I can only guess at the motives of 9p's :-) However, most likely Shuko was worried about his center group. If he plays
Do you mean the continuation would be like this? By my count, White has gained something like 25 points in the corner, compared to the game continuation, so he ought to be able to treat the centre group considerably more lightly. Is Black's aji around a really going to be enough to make up the loss in the corner? -- Matthew Woodcraft Dave Sigaty: I don't know what the continuation would have been. The position in the center is beyond my ability to assess with confidence in order to say what two of the strongest players of their day would have done. I fully understand your point and given the explanation contained in the book, you raise a very interesting question. Considering that Shuko did not take the stone and that the commentary by the pros did not remark on this, I have to think there is more to the position than the commentary implies. This means that the real point of study here is how to attack in the center. That is a very hard, very advanced subject in my opinion. If you check What Is Your Favorite Go Book, you will see that this book is mine. It was the very first book about Go that I encountered and directly led to my continuing interest in the game. I continued to play through this book for pleasure while I was learning the basic rules and concepts. I still remember the thrill I felt when one day I "understood" that Rin's big dragon in game 5 was dead (Chapter 13, figure 11). I could see, without having to lay out the stones on the board, that it could not make two eyes. For the first time I felt like I might actually be able to understand this Go thing! I think if I ever reach the point where I can look at the situation above and say with confidence that I understand why Shuko defended the center, I will have passed another great milestone in coming to grips with this game :-) This is a copy of the living page "1971 Honinbo Ch 8" at Sensei's Library. ![]() |
