I meant the local shape has a ladder as a next move, which the atari destroys. Even if the ladder doesn't work now it might later.

Ah, I hadn't considered the peep. Still, I like playing the hane/atari here. I very briefly considered E12, but I'm tired of being pushed around! I think that I can get some forcing moves here. Of course, I've been wrong throughout this game!

White should probably tenuki now to make n9 become a wasted move as the below is a nice trade for white. I don't understand how Aidoneus thought n9 made this atari more sente, it makes it less!

This is the move I had planned on getting in before deciding to push in with P12. Before playing it, though, I take a look at O13 but I didn't like White's peep at N12. I also considered P13, but it looked like I would be shorting my liberties top right in any chase, and I didn't want to allow the hane over that extension up. I thought about shoulder hits at J16 and L16, but I think that I can get something better after first getting in the move I played. Finally, I considered (worried would be more like it) the condition of my stones on the top left and thought about making an empty triangle with D15, attaching with E14 or F15, the large horse head and cap at E13, and the cap at G15. Now after my move, if White cuts at D15, I am thinking of playing D12; if White then plays D18, I can save two stones with E17--I give more corner/side, but it looks like I get some compensation in the middle. If I actually predict one of Ed's moves, I think that it will be a first!

A few days ago, I was looking this local shape, after the jump, on a real board:

Did you consider any other moves?

If black tries to save the stick of 3 stones after white cuts I fear one or both of black's groups would die. It would be better for black to sacrifice the 3 for now and secure the top group whilst also attacking k17. Maybe white shouldn't cut but attack the whole thing (and strengthen k17 in the process).

The atari was there for some time, since .
I probably had considered tenuki from the atari, but probably dismissed it.

I think that I must play this move. Unfortunately, after setting up my board, I just noticed that instead of White playing D18, Ed can outright capture with E17. It seems too late for me to do anything about it. That's what I get for ignoring the peep! He might later even link underneath at G18 if I just cap at G15. I'm going to have to think about how I might use this or my last move--maybe cut at D9? Nah, he can get out. Then again, maybe I can chase him toward my wall on the right? I'll stop babbling now. I'm just in shock after realizing that I missed E17!

It worked!
I have a thing with these cheese bread sticks.
