4.1.5 Castling
This special move is made with the king and one of the rooks. The king moves two squares
towards the rook; the rook jumps over the king, landing on the square next to it.

White has castled king’s side; Black has castled queen’s side
Note that a player may
not castle in the following circumstances:

If there is any piece (of either colour) in between the king and the rook.

If the king, or the rook with which the player wants to castle, has moved before.

If the king is at present in check.

If the square over which the king must pass (or, of course, the square where the king
would arrive) is under attack from an enemy piece.
4.1.6 En passant capture
This rule originates from the pawn’s double-step move. The diagram shows how it works:

By advancing only one square, the black pawn
would be captured by the white pawn. But is it
possible to negotiate the danger zone by using the
double-step move d7-d5? To prevent that from
happening, the
en passant capture (French.: in
passing ) was introduced:
If, after a double-step move, a pawn is positioned
next to an opponent’s pawn, this (latter) pawn is
allowed to capture the other pawn as if it had been
moved
only one square.
This move is executed exactly as a capture move
after a single move: the white pawn moves from
c5 to d6 and removes the black pawn

Important: Capturing en passant is possible only as a direct reply to a double-step move.
