[Diagram]
Black first to kill

The asymmetry in the setup indicates which side to start on. The only place where White could conceivably get any more eye space is along the side, so attack there first.


[Diagram]
Black first to kill

If White tries to solidify the eye at a, Black's hane leaves insufficient eye space.


[Diagram]
Black first to kill

If White tries to make more eye space, Black falsifies the eye. The circled points are good for at most one eye regardless; it might seem that White can divide the space by playing in the corner, but then all the eyes are false.



[Diagram]
Alternative.

An alternative way of killing is at B1. If White plays at W2, Black will play at B3, so a and b are miai.



[Diagram]
Failure.

B1 attacks in the wrong direction. After W2, there is no way to destroy the eye at the corner.
