I know this puzzle is famous and all, but I actually think its a dud. I know I know, I'm such an armchair GM, but hear my out. As soon as I mention the world "engine" you'll think "THIS PUZZLE IS TOO HARD FOR ENGINES THAT IS YOUR PROBLEM." But I'm not talking about the initial position. The mainline variation has black playing an inferior move, and that is what had me thinking.
As posted on the threat before, here is the mainline variation:
This is the mainline, but it is NOT forced. People conviently like to skip over this variation:
My challenge is for you to prove that this position is in fact a win for white. It seems like a draw, though I am aware that stockfish prunes heavily, so I am legitimately curious, not trying to change everything. I don't know how to set my stockfish so that it spends its time unpruning lines it initially skipped over, instead it is sitting here looking 50 or more moves deep which doesn't help since it already missed the winning variation if there is one.
Can you find a better continuation than stockfish? I'm curious if this win has been proven.
or also by this black gets win
You guys claiming that Black will win are wrong. Have an engine play the game after the pawn promotes to a knight, you're missing the winning combination (which is a bishop move).
xman720: your postion after 17...Kxg4 is a tablebase win for white.
There is a recent article on this site by GM Gregory Serper with some of the "most difficult" problems, including the one under discussion:
https://www.chess.com/article/view/the-most-difficult-chess-puzzle
But please do not believe that anything you find on this site can be catalogued as the "the most difficult problem" or even "very difficult". There is a universe of beauty and difficulty you will only discover once you join a problemist society in your country. That's where the pro's are, not in the coffee pubs visited by Karpov, Kasparov and Anand.

You guys are talking about the HARDEST puzzle. Can I talk about 2nf hardest puzzle please? The problem is I am on my phone and can't post any diagram. After 2hrs I'll post one. It's IMPOSSIBLE to solve
Actually, 4...Kg4 is better than the routine 4...Nf7+?, which loses spectacularly. Despite this, even 4...Kg4 eventually loses. The puzzle leads to a forced win for White. I remember how amazed I was when I saw the solution for the first time. What a gem!
By chance, I know more about the history of this study than anybody else (outside the composer himself).
It was authored by dutch composer Gijs van Breukelen somewhere between 1973 and 1976. We were members of the same chess club and he showed it to me as a peer composer. I didn't realize at the time what a great piece of work had been crafted and that was very negligent of me.
We lost touch until about 10 years ago I received a message from him with a request to confirm that I had seen his composition in the seventies (someone else was claiming it). Unfortunately, I couldn't recall the precise position which is pretty critical in matters of authorship. Since that time some original memories re-emerged regarding the knight play and the Bishop ending up on a4 and now I am pretty certain that it is and always was Gijs's work.
So after all these years: Congratulations Gijs! It is a wonderful study!
I remember reading about the history of the puzzle on gameknot.com. Interestingly, some people incorrectly claim the puzzle was composed by Jim Plaskett.

Gijs has a minute digital footprint which seems in line with his modest personality. After some searching, I managed to locate him in a small village between 2 of the largest rivers in the Netherlands. It's an area I occasionally pass by on my long distance bike rides and I will try and visit him the next time I'm there. Curious to learn about the current authorship status of "la danza del elefante" that made him famous not just in endgame circles but in the wider chess community as well. I do not know if Gijs still actively creates endgame studies but I did find results indicating that he still plays chess at club and tournament level.
what's the result ?
