Sverre has the first two right, but I believe the third one goes like this:

Sverre's answer has this problem:

We don't know who we are; we don't know where we are.
Each of us woke up one moment and here we were in the darkness.
We're nameless things with no memory; no knowledge of what went before,
No understanding of what is now, no knowledge of what will be.

@Dusk Eagle, others:

Problem 3
Has two solutions. Some years ago I attempted to produce a problem with the same essence but with only one solution, but I was not successful.

Off topic: I like your new avatar, unkx. From memory I wouldn't recognize this one to be the same person as the previous one.

B would now play on one of the two outside points as 5th move.

In problem 3 I think Sverre's first move is best because it might induce the W's mistake at Sverre's 2. Cute?

I can't see any difference, either way White gets one internal ko threat and that's it.


Regarding problem 3: I totally missed that :P
