Fischer Random Chess
(...)
No matter where king and rooks are placed at the beginning, if a player decides
to castle, both pieces move to their customary position: in the case of what is
called 'a-castling' the rook is on d1 (d8) and the king on c1 (c8), and in
'h-castling' the rook is on f1 (f8) and the king on g1 (g8). Sometimes this
looks strange, e.g. if only the king moves from e1 to g1 while the rook already
has its initial position on f1! Otherwise players have to follow the usual
castling rules: if king or rook have already moved it is not allowed. Moreover,
castling the king is forbidden if he crosses a square under control.

The Birth of Fischer Random Chess
(...)
Fischer modified and broadened the castling moves for FRC which is not allowed
in shuffle chess. Fischer's improvement allows the possibility of either player
castling either on or into his left side or on or into his right side of the
board from any of these 960 starting positions. Nevertheless, after a-side
castling, the king and rook find themselves on the usual squares: the king on c1
(c8) and the rook on d1 (d8); after h-side castling the king is on g1 (g8) and
the rook on f1 (f8).
Sometimes castling looks odd in FRC: e.g. when the king is in b1 and the rook is
in c1, they pass through a lot of squares and end up in the usual king on g1 and
rook on f1 after a h-side castling, or, when your king is on e1 and a rook is on
f1, you only have to move your king to g1 ('king-move-only' castling). All the
other castling rules apply as in classical chess: e.g. no other piece is allowed
to stand between the castling king and rook; one is not allowed to 'castle out'
of check.

Once the pieces are set up, the rules are the same as standard Chess, though
there are a few interpretations required for castling. When castling, the Rook
and King's final positions are exactly the same positions as they would be in
standard chess. Thus, after a-side castling (notated as O-O-O), the King is on c
(c1 for White and c8 for Black) and the Rook is on d (d1 for White and d8 for
Black). After h-side castling (notated as O-O), the King is on g and the Rook is
on f. It is recommended that a player state "I am about to castle" before
castling, to eliminate potential misunderstanding. Castling may only occur under
the following conditions, which are slight extensions of the standard rules for
castling:
The King and the castling Rook must never have moved before in the game,
including castling. Note that a player may castle at most once in a game.
The King may not be in check before or after castling.
The King may not move through any square (towards its destination) that is under
attack.
All squares between the King and Rook, (... CONFUSING PART IS OMITTED...
SLOBODAN ) must not be occupied by any other piece. Thus, castling cannot
capture pieces.
Castling in Fischer Random Chess can result in certain squares staying filled
where they would have been empty in standard Chess, depending upon the starting
position and game play. For example, after a-side castling (O-O-O), it's
possible to have a, b, and/or e still filled, and after h-side castling (O-O),
it's possible to have e and/or h filled.
