White to play and live - last play marked

[Diagram]

Attempt 1

Tomas (6k): This seems to work. The only b move that is not forced is B6, but I can't find a better response

Dave: This attempt contains the right ideas but is not the best line yet. Instead of B8 above, Black can capture two stones with a. This threatens to play at 9 just like B8 but is bigger.

[Diagram]

Dave's idea

tderz: you mean this sequence ...

[Diagram]

Dave's idea

tderz: Dave is correct, as W9 at c is not atari. %% W9 at d is not helping (black e, when big enough, though sente against White's group)


[Diagram]

Attempt 1 - self question

tderz: What if the clamp B6 here?
It looks stylish.

[Diagram]

Attempt 1 - self question

tderz: W1 is atari (this could be a hint for aji-keshi),
B takes 2 stones

[Diagram]

Attempt 1 - self question

tderz: If W3, the sacrificial squeeze B4 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)

Attempt 1 - self question

tderz:

[Diagram]

Attempt 1 - self question

tderz: W1 dissallows Black to atari at 'a' and capture the black black+circle 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:

[Diagram]

Attempt 1 - self question

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).


[Diagram]

Attempt

unkx80: Is it possible to just play W1?

[Diagram]

Attempt

tderz: Hello unkx80. W1 looks like good style! What about B2?

[Diagram]

Attempt

tderz: W is connected after W1-W9

[Diagram]

Attempt

tderz: W3 at p. B4 tries to resist.
Black cannot link under a to c,
because White has the liberty l and can thus atari at d.

[Diagram]

Attempt

tderz: B6 going for a black snapback-threat at d fails after white's squeeze W7, then W9


[Diagram]

Attempt

tderz: So we could analyze this clamp black+circle and investigate whether it always reverts to above sequences where White played already the atari a.
