What happened to the castling thread?

I posted in it last night, and its disappeared this morning.

I've no idea. Anybody know what happened to it?

Wow! or should that be Woooow!

I thought Fat Lady had tried to do a 2.0-0-0-0 on the PGN thingy and broke it.

I'll try the PGN thing to see if it still works.

By the way, what genius came up with the notation O-O and O-O-O for castling?

The 0-0-0 symbol for queenside castling was added in 1837 by Aaron Alexandre.[10] The practice was then accepted in the first edition (1843) of the Handbuch des Schachspiels."

Can someone please re-post the puzzle? I didn't have any time to look at it and would like to give it a go.

Actually I got it slightly wrong originally. Here is the correct puzzle:


White to move and mate in three moves. Neither White's king nor his rooks have yet moved. Created by Tim Krabbé.

SPOILER (partial solution #1)

Here is the first line.

SPOILER (partial solution #2)

Here is the second line.

SPOILER (partial solution #3)

Here is the third line.

Which was arguably legal at the time that Krabbé composed the problem because neither White's king nor his new rook on e8 had yet moved. Castling was described as "the king moves two squares towards the rook and the rook moves to the square that the king passed over" (or words to that effect).

Am I the only one who thinks Krabbé must have been on some kind of illegal drugs to come up with 0-0-0-0?

From what I've read it seems that a friend of his, Max Pam (http://www.maxpam.nl), actually came up with the idea originally. Krabbé composed the problem which took advantage of it.
