Attempt 1

[Diagram]
Attempt 1  

SnotNose: Cut first (W1). If Black block's White's escape at B4 then White can capture Black's stones at the edge...

SnotNose: Similar to Attempt 1.




Attempt 3

Attempt 3  

SnotNose: White captures Black's stones on the right edge this way too.




Attempt 4

Attempt 4  

SnotNose: Does this work?

Attempt 4 continuation  




Attempt 5

[Diagram]
Attempt 5  

SnotNose: How about this one?

[Diagram]
Attempt 5 continuation  

SnotNose: Bent 4 corner. White lives by squeeze.

But, as unkx80 said, B5 at B6 kills (easy to verify). So we must try something else with W3...




Attempt 6

Attempt 6  
[Diagram]
Attempt 6 continuation  

SnotNose: White dies.


[Diagram]
Solution?  

unkx80: Is this the solution?

SnotNose: Checking continuations...

[Diagram]
Solution?  

SnotNose: This W1 doesn't work.

[Diagram]
Solution?  

SnotNose: This is only a ko. I think White needs to use the threat/aji of a and b to escape or get more liberties for the white+circle stones.
