World's hardest chess puzzle?

Sort:
abcdefghgfedcba

Here's a really interesting chess puzzle I wanted to share with you (mate in one). It is a bit of a trick puzzle because though the move itself is legal, the "consequences" of it aren't. You might think that this makes the puzzle really pointless but I promise you that (if you haven't seen this before) you will be impressed with the answer!

this grap is pointless!!

I'm going out on a limb here. Do you promote the pawn to a black knight?

mate in one if rook was a queen.

Not seeing it.  Looking forward to the answer.

Promoting the b pawn into a black knight....very stupid.

It's not hard, it's impossible, and I've seen the 'solution' before.

I have found the solution:

It was a legal move, more then 100 years ago!

Nice work, Matthew Moreno.  Looking forward to Randomemory's apology.

Promoting your pawn into an opponents piece is not LEGAL, nor is it a tricky move.Silly and idle minds come up w/ hairbrain ideas and this is at the top of that list.

Eddy, let me guess, you decided to offer your opinion before reading the link provided by LoekBergman which explained the history behind this puzzle?  How about you read it, then think for a while, then think some more.

Hey, look, in corpsporc chess this is also a mate in one. The trick is to use my new move, pawn-rook castling you start in the position on the left and go to the position on the right; i.e. the rook replaces the adjacent pawn and the pawn protects the rook from the same file that the rook was on:

What nonsense.  Study some of these Go problems from Japan, 1710, The Hatsuyoron.  Then tell me if you can figure out which is harder.

It is easy, turn the pawn on the top into a black knight.
