Attempt  

unkx80: Looks good, but...

Attempt  

unkx80: Note that here allows White to create a ko.

Attempt (Black not komaster)  

Bill: When Black is komaster he plays for the ko in unkx80's diagram. Otherwise, I believe that is correct.

Continuation  

Bill: Later, White has this sente sequence.

N. B.: If at , @ .

Big corner
