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

Ko
Black can get a ko out of this variation.

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

Not good

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

Reversed order
This reverts to the first attempt

Best candidate
Reducing eyespace no longer works for White.
(I added the marked stone so that capturing at A is not sente)
