Sorry for the delay, I'm still thinking about the position. I will post by the time the weekend rolls around.

I keep looking for something clever, but I don't see anything stellar. Need to just play a normal endgame, I think, and let the chips fall as they may. (Also, I'm not very good at endgame.)

In a live game, I would have thrown all sorts of extra stones at White's groups, trying to find a weakness (that usually isn't there). Forcing myself to read out lines has been a bit difficult. I haven't yet seen anything clever, so falling back to basic forcing moves to keep White from making too many gains.

I had 30 minutes of uninterrupted time to think today (a luxury) so I spent it staring at this group. I think I finally figured out how to take advantage of the aji of these two stones. I think this move will pull me enough ahead to win. Allowing my stones to connect out would be terrible for him, so he has to smother them. I should be able to cut off either the F3 group or the D6 group with enough forcing moves.

Here's the important play. There are many, many options here and the fight is complicated ... I think I have enough aji to make it work, though. Perhaps he sees something I don't, though, and he'll strike me down! Let's see ...

Would you mind showing a sequence or two of what you are predicting?

@emeraldemon:

Sure, let's see if I can give some ideas. I looked at 5 different white responses here ...

For B, the stones escape via the atari at a (seems like a one-way line):

The C variation tries to eliminate the :b31: cut, but I should be able to capture the F3 stones in that case (two diagrams):

If White tries to connect back with a, I can play b and win the capture race, freeing my stones. W is in serious trouble here. Even playing at B doesn't work, as the stones are caught in a pretty good net. Even pushing at F10 doesn't escape (White never has more than 3 liberties at any given time).

I won't show any variations for D or E, but there are a few cases where D turns out like C, and E gets really complicated, really fast, so I'm not going to get into details. I have many lines in my head for this fight, and I think I can pull some gain here.

Sorry for not commenting my moves. I quit playing Go and just want this game to end soon. I'm not motivated to write long explanations.

I think :w28: is a mistake. Atari at F3 later makes it easier for me to cut off a portion of the group. I feel comfortably ahead now.

I think I can't stop black's last stone connecting to his living group, so I think this is the only move
