It dies? Am I missing something obvious?

Just keeping white sealed in, but more solidly than with the direct block at M16. I will surely now get a great result in this corner (either killing white, or if not then at least keeping sente), provided I keep my wall alive. If white doesn't prevent them, then either O14, capturing a stone, or Q14, achieving a connection to the south (while also clearing up some aji) should see to that. The only way I think white can render both ineffective is to play Q14 himself. Then my position does look a little hairy, but I seem to come out happily in the following variation:

White of course has other options (most notably for :w24:

), but I don't see any that cause me any serious problems. Famous last words, no doubt :lol:

(I should finally note that the push-and-cut at M16 doesn't seem to work yet, although it adds aji for white to use in the above variation, and doubtless some others. I still think I'm OK, but it's one more thing to watch.)
