It may depends on the precise phrasing >of the rules. The long castling as described by Tim Krabbe is NOT allowed. The examples he gives in the book are just imaginations (fairy chess), as already hinted at by the title of the book.

Later FIDE rules corrected that. > >Suppose a white pawn promotes to rook on e8.
