carlsen here played Ne5! winning.
It is very easy and I found it almost instantly. No need to test programs with this problem unless they are very weak.

Problem is both moves are based on the same idea, the knight can't be taken by the king else the h-pawn runs in and promotes...

I wouldn't say that - Deep Shredder 11 on a quad isn't exactly weak, and it gives +4.82 for Ne7.

There are two moves that win almost equally on first sight Ne5 and Ne7, I suppose Ne5 is more flexable. Other than the two moves this isnt all that interesting for computers. It is instructive for intermediate players however.
