Tomas (6k): This seems to work. The only b move that is not forced is , but I can't find a better response
Dave: This attempt contains the right ideas but is not the best line yet. Instead of above, Black can capture two stones with a. This threatens to play at 9 just like but is bigger.
tderz: you mean this sequence ...
tderz: Dave is correct, as at c is not atari. %% at d is not helping (black e, when big enough, though sente against White's group)
tderz: If , the sacrificial squeeze destroys White's eye shape
Even if White does not connect after 'b', then 'c' and 'd' are necessary for life but miai for Black. White is dead.
(Forget about c and d, that's the 1st line anyway. The comment only makes sense, if this were the 2nd line)
tderz: dissallows Black to atari at 'a' and capture the black stone.
If Black now captures with 'b', then White lives by capturing with 'c'.
With the proverb 'Your opponent's good move is your own',
Black extends at 'c':
tderz: Now simply White 'a' or 'd', Black 'e' (or 'b'),
White 'd' or 'a' and Black had to make a nakade shape at 'f',
but the eye space with White 'g' would be too big (seki).
tderz: at p. tries to resist.
Black cannot link under a to c,
because White has the liberty l and can thus atari at d.
tderz: So we could analyze this clamp and investigate whether it always reverts to above sequences where White played already the atari a.
