At that level you have to study chess openings and endgame books. You already know the general principles of chess.

Re: Stockfish 8 Failed To Solve This Chess Puzzle

Arpad is simply right about that, and I am a little engine-damgaged as for chess in my old days. :) I think there is a problem on the ini...

A non buggy engine will find all the solutions of all the possible puzzles. Only the time matters.
I do not see 39 moves in your Hiarcs solution to mate.

Re: Stockfish 8 Failed To Solve This Chess Puzzle

It's mate in 39 (77 half-plies), http://www.talkchess.com/forum/viewtopic.php?p=710978#710978 Out of reach for current engines. Ah, so for the first time CCC members and their chess engines cannot solve a chess puzzle :twisted: :P Anyone happen to know, which chess databases have the solved puzzle?...
