This is one of the most beautiful endgames I have ever seen. I descovered it a few days ago. In the diagram position, black to play and win!!! . When I saw it, I put a few engines to work and none see the winning way.

will be ever a moment when a computer can see the winning move?
I paste the whole game. I encourage all to see how black wins this endings.... it's beautiful

Re: A beautiful ending
The first move is key, c3!! and unless a machine can search deep enough to see this is winning they'll see it as going down a pawn.Kempelen wrote:This is one of the most beautiful endgames I have ever seen.

Re: A beautiful ending
Hats off to Zappa Mexico II and Rybka III but also to Tord, as main programmer, and the other Stockfish teamprogrammers for doing it without tablebases or bitbases. Okay, 554 minutes is not fast Maybe Stockfish is much faster but I'm not going to try it as I don't have sufficient hardware, for a comparison with Ted's computer I mean , assuming Ted did use the SMP versions of Zappa and Rybka.

are, by definition, not smart enough to debug it.

Re: A beautiful ending
I don't know if the PGN is faulty but you're quite right...Kxh4?? is a blunder. Kf4! winning easily.Alexander Schmidt wrote:[d]8/8/4K3/7p/p4PpP/P5k1/1P6/8 b - - 1 98

Kxf4 would win easy. Looks like a faulty PGN
