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

"In the 1811 edition of his chess treatise, Johann Allgaier introduced the 0-0 symbol. He differentiated between "0-0r" (r=right) and "0-0l" (l=left). The 0-0-0 symbol for queenside castling was added in 1837 by Aaron Alexandre. The practice was then accepted in the first edition (1843) of the Handbuch des Schachspiels."
Originally posted by Fat LadyNo, it wasn't, not even back then. Krabbé admitted later that he'd left out the final half-line of the rule ("on the same rank" ), purely for the sake of the joke. It was a good joke, but even at the time it wasn't legal.
And White's final move is... O-O-O-O

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).
