Sorry to leave you hanging on this "forcing" sequence, went on a float trip for Easter weekend. Off the map.
Just forcing moves. As always, peeping will remove some cut aji but I don't see any potential for it. |

Peeping fixes weaknesses. To me, white just fixed all of my potential cuts. When to peep can be a tricky question. Because you're making your opponent stronger, it makes your own nearby stones weaker in a sense. A weak group near a strong group is very weak, a group with some weaknesses that's near an even weaker group is much stronger. So, white's peeps strengthened himself on both sides in a sense, but by making my group solidly connected, he also weakened his stones a bit. Of course, it can also make a group heavy if the group is allowed to become a burden, but that's hard to foresee happening to my group now. In my opinion, white's peeps were premature. I think he could have left the aji for later. Of course, later I might respond differently, but I still think that this was too early. Anyhow, that's all feelings. Let's look at some specifics:
starts to make some eyeshape and makes me as black want to play around a to help my group and to hurt his simultaneously. which makes me think that he might jump to b to prevent that point. Attempts to help protect his top. It helps him quite a bit against my potential invasion at c, so he is getting some value out of that move. d looks possible to me though. If a sequence like this occurs, there is a ko. He has a couple of local threats, but I'll do stuff like just attack his weak groups while playing with this aji. Locally, if I win the ko, I break his territory up. If he wins it, my group isn't really adversely affected.

I probably waited a bit too long to play this anyway, but I'm definitely going to take my chance right now. I think I can weather any attack he can muster on my other groups and he's in big trouble if he ignores this peep. I'd feel compelled to protect my stones if he played at a and it would help him connect his two weakest groups.
Also, b is still a spot that I'd like to get. And as before, c is as well.

Separating his groups to keep them weak. |

Heh, we got a comment! Must mean someone is in trouble. This is a key point for the thickness on both sides. My center stones are close to rebellion but I wont let them die without a fight. |

This move separates his stone and makes it crawl on the second line. I started to make diagrams for what may come, but when the diagrams go beyond what I'd normally be able to read in a game, I think it's not quite the spirit of Malkovich, so my main thought is that it's good to make him work to make his cutting stone live. |

I'm asking black if I can easily rescue these stones or if he will make it difficult. |

My laptop keyboard broke, so it's been hard to get this move up. I considered three moves:
The idea of a is that white has to save his two stones and then I can surround his larger group. Something like this:
But. . .
Black is too thin here. The idea of c, is to push the cutting stones very low, but they're too easy for white to sacrifice, so I didn't choose that move. Instead, I chose b with this idea as a follow up.

I think I can get out at 'a' or play 'b' and win a capturing race. |

Post subject: | Re: Dragon Pie vs. emerus #209 |
This move has a local follow up that captures the cutting stones.
So he'll likely protect them, then I can move to surround his group. Also, I'll probably get a forcing move in that helps the status of my group in first. |

Kind of an empty triangle. Both of our center groups are still unsettled so I don't mind much about the lower side stones. |

Well, the move to kill the cutting stones remains, but he realized that I could surround his stones, so he's preventing that now. I can push him a couple of times to strengthen my stones. |

Keep B short on liberties. |
