Sorry for the delay. I needed to be sure that I found the most violent means by which to punish your overplay. ;)
There is some danger that I misread the following sequence but, for the moment, I'm confident in my reading.

Besides, the premise of the game was that the game would be decided by a ginormous fight. Well, here we go!

Atari, extend. Whatever I'm planning to do this really is the only possible move.

Because after this :b87: the ladder at "a" works, he's got a lot of problems if he doesn't just play for the kill of my corner dragon. So most of that bottom side hopefully should be mine after "b". It's a pain in the corner, but the group loss is probably less bad than the territory I'm gaining here (+ him gaining it if I had to run), and most of the bad aji is his elsewhere, so as long as his left side doesn't grow huge, this game hopefully will stay interesting.

Is this the plan and, if it is, why did topazg think it's good for him? :scratch: I hope I'm not missing something very obvious. One way or another, my move is forced.

Well, someone's miscalculating here, that's for sure ... or maybe topazg sees the impending doom of his group and simply "looks for a place to resign," as they say. I'll take some time to think here to make certain that my earlier reading was correct, but I'm pretty sure I win this capturing--assuming I even need to fight a capturing race to begin with. :study:

I analyzed all the ways of playing for Black I could think of, and none of them enable Black to either rescue his group or gain sufficient compensation for the sacrifice. I do need to be mindful of Black trying to exploit the weakness at P8, but I found sufficient countermeasures against all such attempts in the current board position. I'll be watching P8 closely, though, as more stones get put on the board.

Again, the only move I think. Nice and thick. Now White has unconditional sente to enjoy.

Okay, so it's a trade--a good one for White, needless to say. I think I need to make life in the corner with :w1:, but I'll check briefly if there isn't some clever way of going about this. Incidentally, Black seriously needs to worry about the marked Black stones.

Thanks to the marked White stone, White wins this capturing race. Nice ... I hope it works. ;)

I've not read this out fully, but it's hard for White to cut off here without inviting a fight back, and as I'm sort of eyeing up that stone collection up there I may as well encourage White to get all messy with things.

The two Black stones are essentially captured. It would be very risky for Black to try to run with them without additional Black presence in the center. Also, the weakness at P8 is now much less threatening.

Currently, Black is behind in the game by a big margin. For topazg to make a comeback, he needs to make something massive happen inside of White's moyo on the left. If Black does the invasion at E12, I intend to sacrifice the C13 stone in exchange for sente (to possibly attack the lone Black stone in the middle of the board:

I spent quite a bit of time trying to analyze the consequences of this cut. I also considered whether it makes sense to let Black rescue his group on the left in exchange for protecting the cut. It doesn't. The difference in points between the two outcomes is simply too great to choose the safer variation.

I'm not completely sure that this :w1: works in all the lines, yet, but let's see if topazg actually cuts at O14 or not. If he does, I'll refine my calculations accordingly.
