Basic check

The basic approach is to enlarge (Black) and reduce (White) the eyespace. White kills in this approach.

[Diagram]

Ko

Black can get a ko out of this variation.

[Diagram]

Die/Ko

By turning, Black can't enlarge the eye space enough. If He switches B5 for W6, it'll be ko again.

[Diagram]

Not good

Playing B1 here is a bad idea. This is just one straightforward refutation.

[Diagram]

Reversed order

This reverts to the first attempt

[Diagram]

Best candidate

Reducing eyespace no longer works for White.

(I added the marked stone so that capturing at A is not sente)
