and he gets a big corner while I get a big wall.
I always have to be careful about the a-b exchange, as my stones above can run out of liberties very quickly.
In for a penny, in for a pound. I couldn't find a good way to back off from this. I am a little afraid that my resulting "thickness" won't be as thick as it needs to be, but I hope to learn something finding out.

but on rechecking my variations I discovered to my dismay that Black can make the a-b exchange before playing , and then the ladder starting with doesn't work. So it's back to the drawing board.
With my move I threaten to ladder Black's two stones. If he saves them, I have time to hane and pick up the three-stone string. There's one move that tries to save both, but I think I can handle it, barely:

and no ko threat is big enough to stop me from capturing next move.
If I missed some trick of Black's, I'm probably in big trouble...
It now occurs to me that this may not even be sente (there's no life or death at stake, just points). But it does threaten a capture worth 14 points that is basically sente itself (else I squeeze with J16 and J17).
I have to try to make all of my stones work together. I'm clearly behind, so I'm making an ambitious move. I would like to hane at the top, but I think Black would just ignore it; even if I then curl around and atari, and then capture two stones to get connected, I've spent three gote moves. I don't think I can afford to do that.
If I approach from this side and get kicked, I can have a more efficient base. White's bottom isn't gonna make a lot of points because I can undercut the 4th line stones. I can even attack the marked group later.
I don't like this white move. The problem with it is that it invites the black response at c16, leaving white in a position where his head is bumped. This also creates the possibility for the uncomfortable "bear hug" that takes place later when b plays d18.
Edit: unhiding this as it has no effect on the game.
