OK, if he wants to run, he can run. Trying to trap him with D9 just forces him to move toward his friend at G7, and it tends to decrease the liberties of my corner group. Both of those are bad for me. I'll just work toward maintaining the option of making a small stable group on the side. If he gets real aggressive from the north, I'll run northeastward or even due eastward.

During all of this he will have to keep a paranoid eye on F8.

I suspect that his only reasonable play is to pull back to D7. Then I have two good options. I still have not decided which to play:

I prefer to make the splitting move at F7 if I don't get killed on the side.

I hadn't spent too much time looking at

, but I don't think it changes much. I've confirmed that I should still be able to run C6 out after drawing back like this.

The one thing that

does do is make me more tempted to go ahead and play the L5 ad K4 exchanges, and I strongly considered doing so at this point. The reason is that

seems to be more directed towards a running fight (as it gives the black stones more eye space). However, Black still has time to switch to a variation in which I am forced to connect all my stones, so I'm continuing to leave it alone.

In addition,

removes the variation where Black tries to seal white into the side, which was one I was more worried about. So, if I had to guess, I would now expect something like one this:

By playing

here, I'm putting enormous pressure on the G5 stones, but gaining lots of nice outside thickness. I *think* I can still live on the side now, but I'd want to be more sure before playing this route. If I decide the White stones would die, then I will probably play this line:

This way, I have more space for the G5 stones to comfortably live, but at the expense of leaving the C6 group weaker.

I really, really want to play this:

It is the theoretically best move, IMHO. I have a substantial advantage in influence, so I should play separating moves to keep him vulnerable, rather than letting him connect everything.

There are several advantages to this.

1) When his central stones are isolated, he has to play truly dismal moves to keep them safe, something like this:

...or this:

...or something similar, all of which involve me securing lower right side territory and finishing off O3 aji.

2) I can play moyo-making moves in sente:

There is one possible disadvantage:

I might die on the left.

If I can be sure that those stones live, I'm going to play it.

I may need a few days to think about this.

Edited to accept the appropriate trigger.

A trigger of my own:

Comments for observers:

It is a pretty straightforward running sequence from here I think. The question remains when to come back to help G5, but I suspect there will be a reasonable pause when I can do so here:

At this point, G5 is still fairly weak, but I think I can come to A without completely collapsing.

Edit after reviewing the triggers:
I'm disappointed I didn't play the K4/L5 exchanges now. I had figured he'd ignore them now as capturing the C6 stones is pretty large (I've made them heavy.) Missed opportunity I guess.

Perhaps someone stronger could explain this to me, but I don't understand exactly what white hopes to accomplish strategically with this fight. As I see it, the black group based on the marked stone is already alive, so white is to some degree struggling to live with two split groups with only one weakish group on the left to pressure of Black's. I realize that white can't afford to concede one of the groups easily, but this doesn't really seem like a winning direction? Is this just making the best of a bad situation?

My impression is that black will be able to leave the fight with sente without white having accomplished much in terms of building good influence or territory. Then black will be able to take a big move in the top right and white will be in a spot to catch up territorially.

I have to think for at least a few minutes here...

Playing the obvious push through makes me really unhappy. C14 is just close enough to help the netting stone.

I sincerely apologize, but it turns out that these correspondence games have been wrecking my sleep schedule. (I keep waking up thinking about the current positions and then am unable to go back to sleep.) I wish that I could continue, but I just don't think it will be possible for me to do so without causing more problems for myself. Thanks for a very well-played opening, and apologies again.
