Attempt

thanatos13: this is it, right?

Attempt

kb: Doesn't work. Even without the stone, at a captures three stones.

unkx80: This appears to be one of those problems where the original problem poster has left SL a long time ago, yet nobody here is exactly sure of what solution to expect.

Attempt

I suspect the intended solution is something along this line: the key is to force and so that can separate the White stones at the top.

togo: at seems to be enough to defeat this plan.

Foiling the plan

togo: Aforementioned refutation with a continuation ( to at a to d).

Attempt

togo: Maybe ko is the solution ( at a).

togo: Oh, well, forget it: White at b saves the white group (Also with eg. at and at ).

White dies

BCh Maybe this ? White is short of liberties so he can't kill the black stones.

Variation
Ko ?

BCh I don't see how to avoid a ko after white 6, but that's a ko that black takes first. is not a ko as white can force a, b after
