Solution

[Diagram]

Not a marked point but it'll do.

Threatening to capture a pivotal stone demolishes the eye that would have been formed by White playing at a.

[Diagram]

Capturing the first stone

The points a and b are now miai to remove one eye from White's position.

[Diagram]

White hopes for the best

Ignoring the situation doesn't make it go away.

ProtoDeuteric- Would this be gote on white's part?
Mef: Only if white adds another stone and black doesn't respond.
ProtoDeuteric- Maybe I'm just not looking at this problem correctly. To me, black appears to concern itself with the possiblity for white to make eyes around the ponnukied stone. Would a more accurate interpretation be that W2 and B3 are miai, and that thus B3 is, in fact, a response to W2?
Mef: Yes, white has 2 places to make an eye, so after white makes an eye with W2, black destroys the other eye with B3, so B3 is a local response.

[Diagram]

White's strongest resistance

White's strongest resistance is to set up a ko at W2 and fight it. It's the only correct move for White.



Failure

[Diagram]

Failure

B1 only destroys the eye on the outside, but W2 makes the eye in the corner. B3 and W4 are miai for living.

[Diagram]

Failure

In this diagram, W2 lives with two eyes.
