adversary that such is his intention.

[It is usual, in such a case, to say _J'adoube_ (I adjust); but he
may not touch a piece with the intention of moving it, and then,
when he discover his mistake, say, _J'adoube._ The phrase is simply
intended to be used when a piece is displaced or overturned by
accident.]

vi. If a player take one of his own men by mistake, or touch a wrong
man, or one of his opponent's men, or make an illegal move, his
adversary may compel him to take the man, make the right move, move
his King, or replace the piece, and make a legal move.

vii. A pawn may be played either one or two squares at a time when
first moved.

[In the latter case it is liable to be taken _en passant_, with a
pawn that could have taken it had it been played only one square.]

viii. A player cannot castle under any of the following
circumstances:--1. If he has moved either King or Rook. 2. If the
King be in check. 3. If there be any piece between the King and the
Rook. 4. If the King, in moving, pass over any square commanded by
any one of his adversary's forces.

[You cannot castle to get out of check.]

ix. If a player give a check without crying "check," the adversary
need not take notice of the check. But if two moves only are made
before the discovery of the mistake, the pieces may be replaced, and
the game properly played.

x. If a player say check without actually attacking the King, and
his adversary move his King or take the piece, the latter may elect
either to let the move stand or have the pieces replaced and another
move made.

xi. If, at the end of a game, the players remain, one with a
superior to an inferior force, or even if they have equal forces,
the defending player may call upon his adversary to mate in fifty
moves on each side, or draw the game.

[If one player persist in giving perpetual check, or repeating the
same move, his opponent may count the moves for the draw; in which
case touching a piece if reckoned a move.]

xii. Stalemate, or perpetual check is a drawn game.

xiii. Directly a pawn reaches its eighth square it must be exchanged
for a piece.

[It is usual to change the pawn for a Queen, but it may be replaced
by a Rook, Bishop, or Knight, without reference to the pieces
already on the board. In practice it would be
