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.

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.

Yeah, white's not achieving much other than stopping black making big territories. I blame not taking the 3-3 after double approach, corners are cool.

Patient kosumis are a shape I perhaps don't do enough of, but I don't like this one as it doesn't really do much. White still has a nice peeping slide at b11 which is big for points and a base, so black c12 would have nicely prevented that (and aims at corner invasions later). Or d13 is another way to run that has a nicer followup if ignored at c13 (though I expected white would answer). Or just natural g8 as white can't kill the left. Now if white blocks at g8 black's corner is surrounded so moves like white e3 and b4 become more powerful (black corner can become L group).

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.
