Queen is the strongest Piece the Pawns are practically always
exchanged for Queens and for this reason the process of the
exchange is called "queening."

Although a Pawn has comparatively little value as measured by his
mobility--his range of movement--he is really a very valuable man
because of the possibility of his eventually queening.


Castling


Only once in a game is a player allowed to move more than one
piece at a time. This one move is called "castling" and is made
by the King together with one of the Rooks. In castling the King
moves two squares toward the Rook and the Rook is placed on the
square over which the King has passed. In the position of Diagram
3 both players may castle either side.

White, in "castling King's side" would place his King on g1 and
the King's Rook on f1; in "castling Queen's side" the King would
leap to c1 while the Queen's Rook would take his stand on d1.
Likewise Black would castle by either playing the King to g8 and
the Rook from h8 to f8, or the King to c8 and the Rook to a8 to
d8.
