Tderz: I think that White needs sente to live:
The helping proverb is here "8 live - 6 die" (on the 2nd row).
My outcome: Status = white is alive, needs sente, after which a gote seki  for black can result.
But as you see, I make small mistakes, I didn't solve the problem completely - nor Bill's cut at , nor the seki in first instance. Thinking about the problem for some seconds gave me as best starting move, but as better reply only came within writing on the stuff for 10 minutes. Similarly I got it wrong in problem no 44: I never saw that Black is alive with 6 points! Hence, the urge for white to play in problem 44 is much less.
Starting with - away from the corner, thus not at (=) - means using the particularity of the corner
, and are miai, now everyone smells it ...
I am too lazy to edit numerous wrong attempts (leave it to others - hope this one is right). I expect some to be intrigued by attempts for IshiNoShita.
I White tries the same damezumari-trick as in dia.  above: (which makes no sense, because is occupied and cannot become eye-space anymore, black reacts whith an even more normal, killing hane):
Bill: From a yose standpoint, I think this is a bit better for White. After , - and - are sente. The point, it seems, is that the exchange of and makes this better for White than the ko in the next diagram.
Bill: After , - and - are sente.
