parry the check by interposing a man between the King and the attacking
Piece, or capture the checking man.

When he can do none of these three things, he is _checkmated_, and the
game won by the other side. (See diagrams Nos. 9 and 10.) When the King
is directly attacked by the Piece played, it is a _simple_ check; but
when the Piece moved does not itself give check, but unmasks another
which does, it is called a _discovered check_. (See diagram No. 8.) The
third species of check is named the _double check_, where the King is
attacked both by the Piece moved and the one discovered. The fourth
description is called _perpetual check_, a case which arises when a
player has two or more squares on which he can give check, and his
opponent can only parry one check by affording an opportunity for
another. If the first player then persists in the repetition of these
particular checks, the game must be abandoned as drawn. (See diagram No.
11).

_Doubled Pawn._--When two Pawns of the same color are on the same file,
the front one is called a _doubled pawn_.

_Drawn Game._--When neither party can give checkmate, the game is drawn.
This may arise from several causes, as:--1st. _Perpetual check._ 2d.
Where there is not sufficient force to effect a mate, as a King and a
Knight only, or a King and two Knights, &c., &c. 3d. Where one party has
force sufficient, but is ignorant of the proper mode of applying it, and
thus fails to checkmate his helpless adversary within the fifty moves
prescribed by the "Code". 4th. Where both parties persist in repeating
the same move from fear of each other. 5th. Where both parties are left
with the same force at the end, as a Queen against a Queen, a Rook
against a Rook, and the like, when, except in particular cases, the game
