I like that. All the variations I see are winning for white, unless I'm overlooking something (again).

Edit - Okay, I give up, my head's starting to hurt. You stronger guys continue on. 🙂

hmm, I tried to check my solution with an engine, and it was not currect...by the way, my Fritz 10 cannot see more than draw in this position...
hmm, are you sure it is forced win for white ?

For cotio: Whole threads are getting removed just because people "don't accuse" I don't want this puzzle to get removed because of other people's witty stupidity, thanks.

To thaughbaer: That's not a solution. That's one single move.

For the others: Try some more.🙂

Yes vipiu it is correct, engines can't see it.

This is where thinking out of the box happens. Maybe if you solve it you can tell that you see tactics quicker than your engine, huh?😉

Ooh, now THAT'S a challenge. I can't solve it, but I gotta have some engine around that can crack it. (Don't worry, I won't post an engine solution, it's not fair.)

I remember the solution, having seen it previously. So I won't even put it as hidden. It is indeed a nice puzzle.

Zappa Mexico 2 with null move disabled can solve this (though it took 33 mins on my PC). Also, problem solving engines such as Chest can solve it.

After Be7, Black plays Nb6 with the idea of Nd7+ chasing away the White king from controlling g7

I don't see what is the purpose of posting an anti-engine problem. Maybe it's useful for those who are interested in steering their engines into positions which are not evaluated correctly by other engines (which is in fact the essence of correspondence chess).

It's an interesting puzzle for humans, regardless of how difficult engines find it.
