1. Q. to her sq.
2. Q. to her 5th.
3. Q. to her R's 8th.
4. Q. to K. R's 8th.
5. Q. to her R's sq.
6. Q. to her sq.

As a next exercise, put the Queen's Bishop on his square, beside the Queen, and play him as follows:—

1. Q. B. to K. R's 6th.
2. Q. B. to K. B's 8th.
3. Q. B. to Q. R's 3d.
4. Q. B. to his sq.

To these two Pieces now add the Queen's Knight, on his own square, and play as follows:—

1. Q. Kt. to Q's 2d.
2. Q. Kt. to K's 4th.
3. Q. Kt. to K. B's 6th.
4. Q. Kt. to K's 8th.
5. Q. Kt. to Q. B's 7th.
6. Q. Kt. to Q. Kt's 5th.
7. Q. Kt. to Q. B's 3d.
8. Q. Kt. to his sq.

By taking all the Pieces in succession thus, you will speedily obtain sufficient knowledge of their movements to commence the opening of a game; but before attempting this, it is needful for you to be acquainted with the technical terms in use among chess-players, and the code of laws which governs the game.

TECHNICAL TERMS IN USE AMONG CHESS-PLAYERS.

Castling.—Although, as a general rule, the move of the King is restricted to one square at a time, he has the privilege, under certain conditions, once in the game, of moving in conjunction with either of the Rooks two squares. This peculiar movement is called Castling, and is performed in the following manner:—If a player wishes to castle on his King's side of the board, he moves the King to K. Kt's sq., and then places the K's Rook on K. B's square. If he castles on the Queen's side, he plays his King to Q. B's sq, and Q's Rook to Q's sq. The object of this compound move is to place the royal Piece in safety, and at the same time bring the Rook from the corner square into better play.

The conditions under which a player is permitted to castle are:—1st. The King must not be in check. 2d. The King must not have moved. 3d. The Rook must not have moved. 4th. The King must not pass over or on to any square attacked by an enemy's man. And 5th. There must be no Piece, either of his own or the adversary's, between the King and the Rook.
