Thanks for that link, it was fun and took me quite awhile to figure out!

I remember reading about a chess puzzle where a similar "out of the box" thinking was required which would probably put it outside of reach of computer solvers. As a plus it was within currently legal rules. The winning move was en passant and the solution required observing that the only way the situation could have arisen was the opposite pawn moving 2 ranks forward, making this move possible.

This doesn't seems like the kind of move that would be the crux of a puzzle, tripping up both computer and human. En passant captures are a normal, straightforward move in chess that few above amateur level would overlook. En passant captures are the first move you tend to look at if an opponent has moved their pawn two spaces adjacent to one of your own.

If chess is a analogy of war and a pawn infiltrates the other side. I believe he has the right to choose a side. I mean he may scale the castle wall only to die releasing a captured prisoner, or he may disrobe a night and get back on the battle field. I love this idea.

I thought defectors were also executed by opposing armies? Who would want a known traitor in their ranks?

I would want. Just find a way to use him for your purposes..

the amount of times i get called bullshit for doing an en passant or uttering the word zugzwang...

Serious question: Does en passant happen often? I've never seen it happen in the wild (i.e. in games I play), but I just play casually with people.

Even if it doesn't actually happen, it often impacts play, especially in the end game.

> En passant captures are the first move you tend to look at if an opponent has moved their pawn two spaces..

GP is clearly saying that you're not given the information that a pawn has moved two spaces, the trick of the puzzle is to infer from the board's layout that such must be the case.

Seems damned clever to me. From a quick google it appears that such things are known as "retrograde puzzles".

I'm sorry for derailing this, but a) I didn't know that 'Zugzwang' is a word that is used in English, ever b) That pronounciation reminded me of watching the 'Grimm' TV Series, where everything is German based and the actors talk .. just like that

It's a specific term in chess like castling or checkmate.

I haven't played for ages, but I know the meaning of the word bot in Chess and in general.

It was news to me that this word is used outside of Germany. Looking over localized Chess terms they're either German or French. Interesting export.

Also cool: white to move and NOT mate http://www.chess.com/blog/AaronGo/white-to-move-and-not-mate

I can't figure it out but I'm positive that 12 year old me would have lost from this position. Fools mate in an inter-school tournament, the only player on my team to lose his game and thus the only one who didn't get ice cream on the drive home. Still hurts. EDIT: actually it isn't that hard! I really could cock it up from that position.

Not giving icecream to a 12 year old because he lost a game is just outright cruel. :(

It certainly helps to set a pattern of unhealthy eating.

"You loser! Go eat an apple. Us winners are enjoying this delicious ice-cream".

A poorly phrased question that lacks context != cleverness The "puzzle" relies on an obscure situation which isn't even a rule. You might as well claim that the kings can checkmate each other, or that the rook can spontaneously transform into a queen. HEY GUYS CHECK OUT THIS FAKE PUZZLE THAT REQUIRES YOU TO IGNORE EVERYTHING YOU KNOW ABOUT CHESS RULES FOR IT TO WORK

Huh? The solution doesn't require you to "IGNORE EVERYTHING YOU KNOW ABOUT CHESS RULES". I can't speak for all casual players but this is a rule that seems technically possible but just never executed because it's hard to conceive a situation in which it would ever be used in practice. For those of us who don't know this specific rule, there's no excuse for us not thinking-outside-of-the-box...and learning of the "so…

Not really, it's an illegal move which makes it a puzzle from a different game of chess.
