many thanks to all, i had not know this puzzle was allready discuss many times ago, anyway its amazing, i will use that to solve my engine this too.

maybe its difficult because black move Nf7+ is not the best reply, the problem is that black can escape with Kg4 and there is a lot of more variants to search to see any mates.

If it is a mate in 14, then Chest (in brute force mode) is wrong, because I let it search for mate in 14 to completion and it did not find a mate.
