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. :wink:

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.
