Ah, right, the extend is bad because after white double hane black has weird shape. So presumably I should draw back here. Then I guess black will play on the bottom.

White is very thick, so I'm afraid to extend further.

What I really want is to prevent a black move around R12, which will make top right very difficult to handle as well as weakening my right-side hoshi stone. I think black will likely jump out here, and I'll also jump. The result is a pretty flimsy framework, which should discourage black from playing around R12 because that would help white solidify.

I dislike having to play this, but the invasion is too severe.

I kind of wanted to play R5, but that's my greed talking.

As expected, black decides to come inside instead. Again I am having a bit of trouble making my sansan stone work (even now moves like the 3-4 attachment is a bit annoying). I am not sure what black will do. I think jumping out is sort of natural, but then I can shoulder-hit the top right shimari nicely. So I suspect black will play something like R12 instead, and I then plan to playing something on top.

As discussed previously, I will play this shoulder-hit. It does strengthen black's top side, but I still like it since my hoshi stone is in need of support.

I'm not sure whether I should extend or hane here. I would like to get settled locally so that the top is open afterwards, so I'll try to keep a base. I'm not concerned about a cut because I can just extend and let Q14 go.

I considered playing the P13 atari before this extension, but thought it helped black solidify the top too much. Without the exchange black can play at P13 himself, but I think I can just run out and my stone still has aji.

Looks like white didn't get much stronger, huh? What a shame.
