AVAVT: I think this is the solution. After black 5 I can't think of anyway for white to kill black (sorry I edited the solution page by mistake, is there a problem?)
Herman: After , black still only has one eye (at the marked stone). How do you continue from here? (no problem that you edited the solution page, when we find the solution we'll put it there, for now it can remain empty).
I think the solution is for black to allow white to live. However it may be possible for black to first kill white and than get sufficient liberties for himself. I will be posting some variations in a moment.
black get's ko, white captures first though
AVAVT: Hm... I think you're right, maybe is Black's best bet here.
