Solution

[Diagram]

Seki

W1 threatens to make two eyes with a next.

[Diagram]

Var 1 - Seki

If Black plays B2, W3 makes seki. Then, if Black plays inside, White gets a bent four or a straight four and lives. If White plays inside, he only gets three in a row, and dies. The circled point is the only possible weakness, but Black cannot get there before White connects.

[Diagram]

Var 2 - White lives

White has two eyes whatever happens. (W3 at a is a careless mistake - B4 at W3 kills.)


Failure

[Diagram]

Doesn't work

W1 does not work, because B2 reduces White to one eye.
