Huzzah, I'm in!
FWIW sevis, the damage to your shape caused by allowing me to break inside whilst connecting to a completely settled and alive group is pretty large - why did you decide against playing
at
?

The reason I didn't want to cut there is the rather convenient possibility it gives you:

I'd say I still like the current result better, although it isn't too clear. Two :b82:s present, because I don't yet know which one I'd play.

Probably no use putting it in spoiler tags, but wanted to try it once.

This is what I can foresee, and it looks bad for both, but worse for white.

It's very clear the current result is a disaster for B, both locally and globally.
The exchange of

is also bad:

It is more broken shape for B, and all the local B stones are damaged:

First of all, I'd like to thank EdLee for the commentary so far; I wonder if it will perhaps have been fairer if the last few ones were marked as spoilers, seeing as they may affect the game, but it's certainly good to see my errors soon after I make them.
Interesting about K8, I would probably have chosen to save J6 instead (it feels important, although I see no reason why it would be).
Now, to decide what to do about all this. It is now obvious even to me that my last three turns were mistakes (and that I had misread the last two). First of all, probably a good idea to do a count:
$$Wcm77 Prisoner Count: :b1: :w100:
Click Here To Show Diagram Code [go]$$Wcm77 Prisoner Count: :b1: :w100:
White has 16+20+11+13+7+1 = 68
Black has 18+10+10+20 = 58
And that's assuming I didn't miscount. Guessing from how far behind I got so far, I expect the territory on the top-left to be reduced by half and the territory on the top-right to vanish entirely (and probably die). Now, to figure out a way to stop those two things happening, and I might lose by not too great an amount.
I think that playing F11 is going to make it harder to reduce that part. If the top-right is attacked, it can still run, so I think I can save it later. F12 looks good, too, but it leaves too wide an opening -- a white invasion there would cost me more than losing the F9 stones would.
