. With
at or one point right of
, black still can't escape, and white lives in sente.
As for a solution, I haven't found anything that definitely kills white yet

This problem seems solvable, so I must be missing something. =D After this attempt, I looked back and no one has my solution, which is another bad sign~

$$Bcm1 Marcus posted the variations
Click Here To Show Diagram Code [go]$$Bcm1 Marcus posted the variations(Assuming I'm right) I didn't think the problem was that hard, but it may have helped that at first I thought it was "Black to kill" before I realized that black only had one eye himself.
We don't know who we are; we don't know where we are.
. With 
, black still can't escape, and white lives in sente.
Nice!
