[Diagram]
Diag.: Black lives

Black 1 makes miai of A and B. At the same time, it protects against a placement at c. The shape composed here, reoccurs in problems 18 and 34. I'll call it the OkiWantsIkkenTobi for now.


[Diagram]
Diag.: Main line

White makes a placement at 2, but Black calmly takes the miai point at 3. White seemingly connects underneath, but Black has the throw in tesuji at 7. White captures, next ..


[Diagram]
Diag.: Main line (continuation)

Whie is in damezumari. Look how the marked stone comes to aid.



Variations later. Feel free to add some of yourself.

KarlKnechtel: Here's one:

[Diagram]
Diag.: Wrong (1)

Black thinks himself clever for making an eye at a, and keeping the stones on the right connected via a BambooJoint. But when white probes, black effectively has six on the second line in gote, and so the double hane and the placement at 8 kill. I think.

If black doesn't defend the cut, there are some other possibilities. One is the sagari trying to claim a second eye:


[Diagram]
Diag.: Wrong (1a)

White calmly makes the placement at 4, and black still can't profit by extending the EyeSpace - the hane this time leaves black with a filled farmer's hat big eye.

The other is to secure the eye at a and hope for another at b or c:


[Diagram]
Diag.: Wrong (1b)

I'm not sure how to refute this, since d and e seem to be miai for life. Maybe white 2 is wrong?

unkx80: Black lives here. White 2 is wrong.


[Diagram]
Diag.: Wrong (1) Corrected

unkx80: White has to play at 2, threathening to connect at a.


[Diagram]
Diag.: Wrong (1) Corrected

Black's strongest play is at 1, threatening to make an eye in the corner. If white 2 plays at a, black can make a nasty ko at b.


[Diagram]
Diag.: Wrong (1) Corrected

Black 1 to 5 attempts to create a seki. However, white 6 is a tesuji that will kill black.


[Diagram]
Diag.: Wrong (1) Corrected

Black 1 and 3 tries to make a bent four.


[Diagram]
Diag.: Wrong (1) Corrected

But the placement at white 1 kills the entire black group. Beware though, if white 1 carelessly atari five black stones at a, black lives at 1 instead with the under the stones technique.

KarlKnechtel: For completeness, note black cannot live via under the stones by sacrificing *six* stones either:


[Diagram]
Diag.: Wrong (1) Corrected

White is forced to capture at 3 (!) because otherwise black captures at a and has two eyes. Black tries to continue via standard under the stones technique, but ends up AlmostFilled with a DeadShape? (there is no need to force the issue with a play at a because of this filling):


[Diagram]
Diag.: Wrong (1) Corrected
