From the article:
The puzzle may seem hopeless for white, with just a King and four pawns remaining, but it is possible to draw and even win.
Scientists have constructed it in a way to confound a chess computer, which would normally consider that it is a win for black.
However an average chess-playing human should be able to see that a draw is possible.
I wonder what "average chess-playing human" means ...

Originally posted by byedidiaYeah, just looked at it. I assumed it would be an actual board not one of green pawns toys.
Looks like a draw to me, and I'm no master. If white just diddles with his king on the light squares, black has no way to make progress.
Can't believe a computer can't see this as a draw.

Like any thought is necessary. Durh. Just move the wK around and black can't do sh|t, as another poster has already noticed [and no doubt every reader of the thread who actually bothered to click on the link].
If a human can't solve such a puzzle in a nanosecond, they need to find a different game to play. 😛🙄

“If you put this puzzle into a chess computer it just assumes a black win because of the number of pieces and positions, but a human will look at this and know quickly that is not the case,” said Sir Roger.
Looks like Sir Roger believes ahead means a win. My computer on deep analysis never came up with a win, just a consistant advantage which I assume is on material.
Funny how I was thinking of a nrw way for computers to calculate giving only how strong the piece is on the board. My thought was by calculating mobility for each piece or how close a pawn is to promoting.
I have many issues with this article. First is the idea that a computer will botch this up. The computers very clearly make the right moves even if their evaluation of the position is wrong. My computer, HIARCS, has harmless king moves for every move in all the lines. Second is the use of the phrase, "force stalemate." Stalemate and draw are not synonyms. The third is this sentence, "The three bishops forces the computer to perform a massive search of possible positions that will rapidly expand to something that exceeds all the computational power on planet earth." Really?

A much harder puzzle is: How do you get to this position?
Edit: but since I'm stuck at work anyway...
