OK, I admit it: I chickened out. A player who was really sure of his plans and his reading would have tenukied on one of the last two moves. I think my reading is good, but I'm not absolutely sure.
If I stick to conservative moves, I think that I can stabilize the situation on the lower side, and come out of it with sente.

I don't see how this white group lives. I've found what I believed was a way to live, then I found that life was impossible. Then I found another one, and soon after found that life wasn't possible then either.
I've gone back and forth six times, and it is still before breakfast.

I heard somewhere six points is alive...
In response to C10, Black can play B11 and B9 is no longer forcing. I tried a bunch of variations and couldn't see it make life. I don't really know how to post files here, but I still don't see white living there. Black seems completely or nearly connected and quite safe in all parts of the board. White dying here is GG, imho. O3 seems to have a bit of aji as well in the corner open for black still, though using that kind of Aji is not something I am very good at.
Sorry for the delay. I overlooked the last Black move. Considered only B5. Now it is hard to find the way to live.
Here White can start a ko with B11. Not really good but better than nothing.

I will post some other variations later.
I think A11 is not necessary. If black plays B11 in response to A10, white still has to get another eye from attacking the D7 stone. I don't think it is possible, but perhaps.
