I think I have to protect the cut. I like simply connecting more than D8 because it works better in possible variations with bC10 wB11. |

Connect after the peep again. |

Trigger: I'll play any or all of this:
I would like to take this, of course...
...but it is way too slow. I don't want him to take it either. To prevent that, I have contrived to have my cutting stones positioned so as to make the push through at J12 as unpleasant as possible.
Rescuing F11 is probably gote for white. |

If Black connects White will start the attack on Q9 stone. This looks more safe than the trigger variation. Black has about 30 points at the bottom and about 20 at the top right. White has about 25 at the left and initiative. So I assume that I will be able to close the bottom right corner with 15 point and gain about 10 points in the center which makes me leading by komi.
If Black protects the right side then White can cut at G9 with more safety or consider playing H8 to destroy the botom territory. |

I don't understand this. My opponent goes to a lot of trouble to surround me, and then when his objective is within his grasp, he goes off in another direction. I'm not going to look at the proverbial gift horse. He may try to start something over on the right side, but there is lots of room over there. |

@Observers: The last thing that I want to do is make my Q9 stone heavy... As I noted a few moves back, my opponent has out-walled me. His stones in the upper middle, which I had intended to be a target since move 19, have now become strong. This forces me to change my entire game plan. I'm changing from the hunter to the hunted. If I were wiser, I probably would not have been grabbing territory with 43:
Instead, something like this may have been more consistent:
But here we are: me with a lead in territory and him with a lead in influence. So I have to reset my goals. In particular I have to make sure that he does not capitalize on his influence. Fortunately for me, he is taking his time about doing so. IMHO, has last play was unnecessarily defensive. My play is based on the general opinion that his last move was conservative, and upon the specific opinion that I can make him overconcentrated. Given the array of eastward-facing stones that white has - here marked with circles - his play at 64 seems too small.
IMO, if he wanted to play in that direction, it looks better like this:
But as he played it, it is so close to his other stones that their strengths overlap. I can play a contact move, knowing that if he captures it, he gets a ponnuki that is way too close to his wall:
While he is making those three additional moves to capture, I get three moves also - which I hope to be more efficient. A possible example is this:
On the other hand, if he leaves my stone uncaptured, it will inhibit the direction of play of his wall, and it will assist in the fight on the east side where my one stone will be have more eastward influence than a handful of his.

Usually the best way to answer a peculiar move is to play something normal. So let's answer the attachment with hane. If black tries to separate from it can continue like this.
Otherwise white will just connect his stones. I could play P10 immediately but Black may think of sacrificing his Q9 stone and killing the white center group. With , exchange it will be more difficult. |

Black can also try something like this but I don't think it works for him.

Grab some popcorn. This could blow up real soon.
I'd like to play the atari at 1. If he replies at 2, then my stone is worth more to influence the right side than his.
But I'm afraid that he might sacrifice and tenuki. Suddenly his right side gets big:
...and his center group can't be killed. So I'll play sabaki. I'll let him decide what is important to him, and I'll slide away with whatever is left. If the whole right side ends up trashed, I'll probably get a modest addition to my corner and he'll get some center territory. At that point the large areas for making territory are all gone, and I'm ahead by about 10 points. If he comes out with sente, it is an even game. If I come out with sente, it should be an easy win.
BTW, all of my stones on the right are light. In my reading, I have found variations where each of them gets sacrificed. |

Missed that move of Joaz. The calm reply is O10. It is probably enough to lead because Black has weaknesses at the upper right corner and at M3.
Here Black can start some complications with .

You can put the popcorn back in the cupboard.

@Observers: Hmmm...I thought that he had to capture one of my sacrifice stones and therefore I would come out of this with sente. There is a lot of aji there... ...I must think for a while. The first thing that occurs to me is mild amusement: I was the attacker early in the game, until I resorted to territory grabbing with O3. Then he was attacking me. Now he lets that fizzle out so that he can grab territory in the same corner. The second thing that occurs to me is that he may very well know that those two stones are dangerous, but he did the same calculations as I and concluded that I would be ahead if I came out of the right side with sente. So he figured that he had to act as though he had sente and hope that the aji is not too bad. The third thing that occurs to me is that I am hungry. I'm taking a break for dinner. |

Forced. Ponnuki in the center. Should I add 30 points to my territory estimation? |
