Re: Wich Engine can Solve this Puzzle?
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.

Re: Wich Engine can Solve this Puzzle?
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.Vinvin wrote:HIARCS in 2005 : http://www.talkchess.com/forum/viewtopi ... 285#642285Engin wrote:i watched a video on youtube that is very amazing here:

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
