Pro-pro 2 stone game, no komi, White to play. No guarantee that White played the best or only move. I just like it. ![]() Where would you play? |

Some initial thoughts of where my eyes lead, not picking any yet...: |

Post subject: | Re: Guess the next move |
I happen to know the answer - the reason why will probably be obvious once you know the players - but macelee's suggestion caught my eye because just yesterday I happened to see that tesuji in an old game I was entering. At the time, it gave me pause for thought because it's a tesuji I remember very, very well from beginner days, probably from the old Go Monthly, yet I have rarely seen it in real games. That got me to wondering (a) was my impression right - apparently yes, for Kombilo shows fewer than 400 games with that tesuji - and (b) why. It's obviously a good move in principle, as many of the very top pros play it, and the shape in which it can occur is far from rare. So I infer that the planets have to be in a certain conjunction to play it, or it may just be a style thing. But if pressed, I'd say that a top pro, and especially White in a no-komi game, is ultra-chary of fixing shapes. Especially if a similar effect can be achieved by the much more subtle means employed here... But what are your thoughts on that tesuji? |

I'm just a former chess player with materialistic attitude ![]() After that sequence, (i) the white group at the border is settled and (ii) it is probably sente as black might want to protect (a). After that, a white play around (b) looks nice. |

Even though white can just manage to live inside (starting with clamp not (a)) black defending lacks fighting spirit, and if he did want to defend it would be to capture that white stone on the outside as that is a more valuable way to fix the corner aji. |

Here is how Honinbo Shuei played against Karigane. I suppose that you could call ![]() ![]() With ![]() ![]() With ![]() ![]() |

Edit: Bill posted the answer before I got this up, but I'll post it anyway to preserve my kyu level reasoning for all to see. ![]() My considerations:
It's a bit of a weak connection with the lower left group, but I think this leaves follow ups at a (build a huge moyo) or b (attack the bottom black group and potentially build a moyo on the right-center half.) Whit still has enough eye potential in the lower right that I think he can manage that group of black jumps out at c and attacks at the same time. |
