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.

Is this GG? I don't see a way to live. I previously thought E6 might be something, but I now don't think it can work.

A correction to the game record: White has captured 3 prisoners, not 2 (the third one was with move 76).

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 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.

Sequence? Singular?

There is a whole bunch of them. I can barely handle six impossible things before breakfast, but not near that many after dinner. :lol:

Rather, I'll try to break it down into several little battlefields. I'll show how each of them work in isolation. I'll leave it to you observers to figure out how they interact. :twisted:

First, let us observe that the stone that I just played cannot be killed, nor can white connect under it. Most importantly, B10 by white is gote in all variations. Here are several general patterns:

Next, let's look at the lower end of the group. This is a pattern that is probably familiar to all of us. It has no branches ( at least no reasonable ones for white that I can see ):

White's latest move is probably the best. It seems to get the most room for eyes. But by my reading it is not quite enough.

His move starts to trap my D7 stone. I'll sacrifice it if he wishes to kill it, but in return he will have to let me slide under into his eye space.

He can kill it now with one move, but while he does so, I can attempt to rescue it and turn it into a false eye. He then gets one eye along the side.

If he takes two moves to capture it, he can turn it into a real eye, but with my intervening two moves I can slide into his eye space along the side.

There is also one other line in which he captures D7 AND blocks my invaders underneath
but I play D8 - and in some lines C8 - leaving him with one big eye.

I don't have time to edit and post diagrams, but I can say with 99% certainty that this white group is dead.

I almost went for this line. It seems more solid than the line that I played.

...because one of the netting stones gets laddered first.

Therefore white dies, right? It looks like he does. ( A9 and A7 are miai )

However, if D8 is good for me, then according to the proverb, it should be good for him.
I was idly looking at it, assuming that I would kill easily if I got the vital point at B8.

But white has this sequence:

First, he plays A10, threatening to either kill B10 for an eye, or connect underneath to his stone at B13. I have to reply.

There are more complicated replies than this, but they all end in sente for white, and they all prevent the black connection underneath at A9.

Next, white attempts to capture the D7 stone:

Again, the net does not work:

However, while playing a failed ladder, white has enclosed just enough space on the back side of the ladder, and finishes with a second eye like this:

If I can find this ko, my opponent can find it also.

So at move 93 I have to play B6 instead.

In advance I thought that this gives me more chances than C4 or A4 but may be I was wrong.

I think I made a mistake in English in my previous comment. It should probably be "Couldn't find anything better" not "nothing better".
