THE RULES OF THE GAME
BOARD AND MEN
The game of Chess is played by two armies who oppose each otheron a square board or battlefield of sixty-four alternate whiteand black squares. Each army has sixteen men; one King, oneQueen, two Rooks (or Castles), two Bishops, two Knights and eightPawns. The Generals of the two armies are the two playersthemselves. The men of one side are of light color and are calledWhite, those of the other side are of dark color and are calledBlack.
The object of the game is to capture the opposing King. When thisis done the battle is ended, the side losing whose King iscaptured. To understand what is meant by the capture of the Kingit is first necessary to become acquainted with the lawsaccording to which the different men move on the board.
To start with, the board must be placed so that

To the beginner the lines of play discussed in connection with Diagrams 47 and 48 will have appeared rather complicated. This they are, indeed, even for the experienced player; but it is by no means necessary to memorize any of the variations. The important thing to realize is the fact that in a position where both players have castled on the Kingβs side, a dangerous weakness is created if the g-Pawn is forced to move, and if pressure can be brought to bear upon the two squares which through the move of the g-Pawn have lost their protection; moreover, that a method to create such a weakness is the pinning of the hostile Kingβs Knight and the advance of the Queenβs Knight in the center.
Another important point that the variations discussed will bring out to the observant reader is the order in which the different pieces take their turn in the battle. First come the minor pieces, then the Queen and then the Rooks. This, of course, is not a rule that has to be adhered to under all circumstances, but in most games it is a good rule to follow. The reason is obvious. The Rooks have no opportunity of making themselves useful until a file has been opened, while the Queen often finds an occasion to enter the battlefield on a diagonal. Only in such games can the Rooks be made to work at a comparatively early stage of the game, in which the players have not castled on the same sides of the board. For then the advance of the Pawns in front of the Rooks does not create weakness which endangers their own King.
The following middle game from a match of two masters furnishes an example. After Whiteβs seventh move the position of Diagram 49 was reached, in which Black continued with P-b5 with the view to playing B-g4 and Kt-d4. White replied (8) B-b3, B-g4; (9) Kt-e2. Better would surely have been B-e3, which develops a new piece. To allow the exchange of f3 which forces the g-Pawn out is dangerous because Black may castle on the Queenβs side and storm with the Pawns of his Kingβs wing.

From Blackβs next move, Q-d7, it is indeed apparent that he has decided on a maneuver of this kind. The game continued: (10) P-c3, Bxf3; (11) Pxf3, Q-h3; (12) Kt-g3, P-h5; (13) B-e3. He cannot play R-e1 on account of Bxf2+ followed by Qxh2+ and Qxg3. (13) β¦, P-h4; (14) Kt-h1, R-h6 and wins, for if White takes the Rook, Pxh6 opens the g-file and the other Rook occupies it with deadly effect.
In the last example it was easy for the Rooks to take an active part in the battle because a file was open which enabled them to bear down on the opposing King.

In the majority of cases no open file is available on the wing and the attack with the Rooks is then much more difficult. There is little use in advancing the Pawns on the wing on which the hostile King has castled unless one of them can be exchanged so that a line is opened which the Rooks can occupy. As a rule such an exchange is only possible in case one of the Pawns in front of the King has moved. In the position of Diagram 50 for instance, White is able to open the h-file by advancing the h-Pawn and exchanging it against Blackβs g-Pawn, while Black, who would like to use his Rooks in an attack on the Queenβs wing, has little hope to open a file on that side of the board. If Blackβs g-Pawn were still on his original square, the advance of Whiteβs h-Pawn would be of no avail. Black would simply wait until the Pawn has advanced to h6 and then he would play P-g6 so that Whiteβs own Pawn would block the h-file for the Rook. In the above position, which occurred in one of six simultaneous games played by the author in a blindfold-exhibition, the attack developed as follows:
(1) P-h4 P-b5
(2) B-b3 Kt-a5
(3) P-h5 Ktxb3
(4) Pa2xb3 Q-a5
Black has succeeded in opening a line also, but he cannot get his Rooks working in it. His last move threatens mate in two moves by Q-a1; Kt-b1, Bxb2; but White simply defends himself first against this threat and then proceeds with his attack on the Kingβs wing which is irresistible.
(5) K-b1 Kt-c6
(6) Pxg6 Pf7xg6
(7) B-h6 R-f7
(8) Bxg7 Rxg7
With this exchange White has weakened the defense around Blackβs King who has now only the Rook and himself to rely on for protection.
(9) Kt-g5 P-d5
Black opens the seventh rank in the hope that it will enable his Queenβs Rook or his Queen to come to assistance. But so great is the advantage afforded White by the open h-file that he can sacrifice his Knight to break through Blackβs chain of defense and force the mate before Black has a chance to touch his Queen or his Rook.
(10) Ktxh7 Rxh7
If Q-c7 or Ra8-a7, White continues (11) Q-h6! Rxh7?; (12) Qxg6+, K-h8; (13) Q-e8+, K-g7; (14) Rxh7+, Kxh7; (15) R-h1+, etc.
(11) Rxh7 Kxh7
(12) R-h1+ K-g7
(13) Q-h6+ K-f7
(14) Q-h7+ K-f6
(15) Q-h8+ K-e7
(16) R-h7+ K-d6
(17) Q-f8+ K-e5
(18) P-f4+ K-d4
(19) Q-f6+ K-e3
(20) R-h3+ K-d2
(21) Q-h4
and Black resigns as there is no defense against Q-f2.
Diagram 51 shows a similar example, the only difference being that it is not the advance of the Black Knightβs Pawn but that of the Rookβs Pawn which gives White an opportunity of opening a file for his Rooks. He will accomplish this by advancing his Knightβs Pawn to g5 and exchanging him against Blackβs Rookβs Pawn. If he does not want to play P-g4 on the first move, because Black could take the Pawn with his Knight, he can prepare the advance by R-g1. But he need not really fear the loss of the Pawn, because in taking him Black would himself open the g-file for Whiteβs Rook and White is sure to obtain an overwhelming attack. It would, of course, be futile for Black to try and stop the advance of Whiteβs g-Pawn by P-g5, as White would then simply open the Rookβs file by P-h4 and Pxg5, quite apart from the fact that he could sacrifice his Bishop e3 for two Pawns, thereby depriving Blackβs King of all protection.

The play might proceed like this: (1) P-g4, P-g5; (2) Bxg5, Pxg5; (3) Qxg5+, K-h8; (4) Q-h6+, K-g8; (5) P-g5, Kt-e4; (6) Ktxe4, Pxe4; (7) P-g6, Pxg6; (8) Qxg6+, K-h8; (9) R-g1, etc.
Ordinarily both players castle on the same side of the board so that neither of them can advance his Pawns in an attack against the opposing King without weakening his own Kingβs position. Only if a player holds more territory and has a greater number of pieces on the Kingβs wing than the opponent he can embark on an attack which involves an advance of the Pawns in front of his King. Diagram 52 offers a typical example.
