The hardest chess problem in the world?

Sort:
Azukikuru

Over the weekend, I came across this puzzle, which I found too difficult to solve. It's a mate in one - yes, you read that right. Good luck!

 

Hint: This puzzle is so old, it pre-dates the publication of FIDE's official rules of the game.

In case you're tired of trying to come up with an answer, you can find the correct one here.

It's been around here before, I think. Something like promoting to a Black Knight?

I have a harder one, even the computers can't solve it (Can White force a win?):

Misleading, there is NO mate in 1! Promoting to a Black N is an illegal move!

Promote to a golden magic king. Then can walk into check because all moves are legal for one including teleportation

maybe some kind of castling? Castling´s rules were pretty different until the creation of the FIDE rules. For example, before FIDE´s rules even vertical castling was theocally posible . Wont surprise me hear about diagonal castling... And in this case, it is mate if a diagonal castling is applied. Who knows...

are y'all reading the hint? it PREDATES modern chess rules.

@CharlieYZ no wonder the analysis says it's fake! the analysis only analyzes modern chess rules.

@Samurai-X same for you. in this age, it's an illegal move, but it wouldn't have been a few hundred years ago. it's m1 but not with modern chess rules

I'm afraid it always was a joke. Nobody has shown any pre-modern publication with rules that allow it. Of course, before FIDE existed (pre-1931) there might be someone claiming to have visited a small town in Kazachstan where they played by different chess rules. That's the way frauds and fantasists weave their web of lies. It is just a myth created to have a myth

.It's worth mentioning that there is a small, modern stream of joke problems created by otherwise decent chess composers. Everyone likes a day off work and that's how you do it in chess. Commonly they don't tell you which joke rule(s) they use but they let you know it is a joke through text or context ! Or, you create a new fairy type (chess variant) by publishing the changed rules. There are thousands of fairy variants used to expand the domain of chess compositions.
