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

$$.........X..|
$$....XXX...XX|
$$....XOOXXXO2|
$$....XO.OXOO1|
$$......O.O.3.|

Sverre's answer has this problem:

$$.........X..|
$$....XXX...XX|
$$....XOOXXXO2|
$$....XO.OXOO.|
$$......O.O.1.|

@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.

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
