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 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:
$$Bcm34 Risky line

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:

I really, really want to play this:
$$Wcm31
Click Here To Show Diagram Code [go]$$Wcm31It 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. When his central stones are isolated, he has to play truly dismal moves to keep them safe, something like this:
$$Wcm1
Click Here To Show Diagram Code [go]$$Wcm1...or this:
$$Wcm31
Click Here To Show Diagram Code [go]$$Wcm31...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:
$$Bc
Click Here To Show Diagram Code [go]$$BcThere 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.

A trigger of my own:
If Black extends, White makes a tiger's mouth.
$$Wcm31
Click Here To Show Diagram Code [go]$$Wcm31Comments 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:
$$Wcm35
Click Here To Show Diagram Code [go]$$Wcm35At 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.

@Uberdude:
Yes, that's exactly what I was afraid of. But his first trigger treated
as sente, which meant I could still come back to the C6 group. The fact that he was willing to treat
as sente was what I regarded as my missed opportunity. Hopefully he'll still feel the same way later when I play it.

Click Here To Show Diagram Code [go]$$Wcm31Perhaps 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.

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.
