they capture diagonally to the right
and left, again only one square, and only forward. Therefore a pawn
can only capture such pieces or pawns as occupy squares of the same
colour as the square on which it stands. If, in moving two squares, a
pawn traverses a square on which it could have been captured by a
hostile pawn, that pawn has the right to capture it, as if it had moved
only one square. This is called capturing EN PASSANT. However, this
capture can only be effected on the very next move, otherwise the
privilege of capturing en passant is lost.

If a player succeeds in reaching the eighth rank with one of his pawns
he is entitled to call for any piece of higher grade, with the exception of
the King, in place of such pawn.
Each move in a game of chess consists of the displacement of one piece
only, with the exception of what is termed "castling," in which the King
and either Rook can be moved simultaneously by either player once in
a game. In castling, the King moves sideways to the next square but
one, and the Rook to which the King is moved is placed on the square
which the King has skipped over. Castling is only allowed if neither the
King nor the Rook concerned have moved before, and if there
