Black to move: Find the first 5 moves of the main-variant that kills W unconditionally or in double ko. If there are more solutions find the most profitable or most simple one. I publish the ( book ) solutions after 10 days. Difficulty: sdk
I'm interested in how you estimate the difficulty of each problem. So I look forward to reactions like:
b > a = d > c ( c is easiest ) or
b = 500 s, a = d = 100 s, d = 40 s. ( for this 7 kyu, s for seconds ) or
b = 4 k, a = d = 6k, d = 8k.
I recommend the book "One thousand and one Life-and-Death problems" by Richard Bozulich, Kiseido Publishing Company.

Re: 4 LD's from 1001 L&D problems
Because I'm only a 10k I only looked at the easiest problem and after some time I think I found the solution.
While I was teaching the game to a friend of mine, my mother from the other room:
"Cutting? Killing? Poking out eyes? What the hell are you playing?"

@Dusk Eagle:
@jts
. I got a and b right, at least if sverre is right. I could not solve c. I think the double ko bit was something of a hint.-

If you want to see the solutions: check Sverre. But they are not the only correct ones.
