BQM 18
The following position comes from the game between Wu and Sakata they played in April 1939, and which is extensively commented in Sakata's book KillerOfGo. Sakata plays Black. The question arises at move 35.
Wu's last move is marked. Sakata discusses three possible answers to this nozoki: connect at A, connect at B, or block at C. Sakata says: The connection of Black B here, will be followed by White's cut at A, Black D, White C, Black E, White F, Black G, White H and Black's three stones are captured. Then, between brackets, he adds a puzzling statement: (Or else, White will play C as a diagonal move at F) which I restate as Or else, White will play the diagonal move at F instead of C. Now eat this ! Is Sakata saying: "here is a sequence, and well, if that doesn't work, there is another that will work" ??? I'm stunned. I read this comment over and over again, and every time I get more bewildered. Okay, let's try the sequence.
Sakata says that the three Black stones are captured. Let's try saving them by attempting the connection underneath, and play A.
In this variation, White can try whatever she wants, she's short of liberties. Her five stones get captured.
Again, White is short of liberties and loses the fight. This answer does not yet threaten the corner. (Please confirm).
This answer threatens the corner. If Black continues at 3, then up to 10, Black is still not alive. If he lives with A, White connects underneath with B. I guess variation 3 is what Sakata has in mind. But then he should write: "The three stones get captured or the corner dies." Or does that speak for itself ? Please review. But then again, what on earth does he mean with the brackets phrase ? Is it just as good to play the kosumi ? Is it better ? He doesn't calculate because he "knows" ?
Ah, I've got it. There is a stone missing, the marked one, which changes everything. And about the stunning remark, I guess Sakata wants to say that White can play either way. It's 8 AM now, and I'm much calmer. This is a copy of the living page "BQM 18" at Sensei's Library. (C) the Authors, published under the OpenContent License V1.0. |
