What can black do?

For me, the circled points are all candidates for the first move.

[Diagram]

First line

First candidate: reduce the eye space. We can see there's a ko this way.

[Diagram]

Second variation

Can Black do better? Yes. If W2 then B3. But can White do better? Yes:

[Diagram]

Variation 2B

[Diagram]

Var 3

[Diagram]

Var 3B

Same as Var 1 but different order. This made me realize White has an option in var 1:

[Diagram]

Var 1B

It turns out W2 is the vital point in this position.

[Diagram]

Var 4

B1 invites W2 on the vital point

[Diagram]

Var 5

This exchange doesn't help.


This problem needs 8 diagrams of about 5 moves deep. It's easy to miss variation 1B, think that 1 is the solution, while 3B is the main line.
