Vertical castling

Just dumping this here as a fascinating chess curiosity.

It's amazing how the solution to this problem was actually legal until the 1970s.

Wow

Woah, thats cool! It seemsso complicated idk why...

Cool! I don't envy those who tried to solve it on their own when it was published :-)

> Some people have no imagination

Indeed. It's a shame FIDE took a boring (albeit a simple) way out

It has a name.

@Sarg0n Concerning the last puzzle:
1. a8=R Kh1 2. castling with the king going to c1 and the a8 rook to d1?

That's indeed an interesting question, how "moving two squares towards the rook" is to be interpreted when they're neither on the same rank nor the same file.

Rather than giving the player a choice and making the notation even more complicated, I'd suggest you simply have to move in a straight line towards the rook, for a distance of 2 squares.

So, for white, castling with a rook on a8 would let your king end up on approx. d2.7 .

( d.00772 2.73649 to be more exact. Even if it wasn't for the checkmate, this would be a great move. Just think about how save it is there! How to even check a king that's sitting in a weird superposition between the squares d3, d2, e3 and e2?)

You are quite late!
And before, every organisation had terrible rules only to be criticised by public and corrected again.

The problem isn't with vertical castling, the problem is with pawns refusing to march horizontally and to capture backwards.

Great stuff.
Thank you.
I wonder how a scrutineer in a tourny would judge if that happened and the inevitable protest was fired in.

Never heard of vertical castling! On that basis I could never have solved this puzzle. Given I only took up the game in my much later life, that’s probably not a shock.. but what an interesting concept. Fair play to the bloke who came up with this puzzle.
