DESCRIPTION OF THE CHESS-BOARD AND MEN.

The game of Chess is played by two persons, each having at command a little army of sixteen men, upon a board divided into sixty-four squares. The squares are usually colored white and black, or red and white, alternately; and custom has made it an indispensable regulation, that the board shall be so placed that each player has a white square at his right-hand corner.

The following diagram represents the board with all the men arranged in proper order for the commencement of a game:—

No. 1.

BLACK.

WHITE.

Each player, it will be observed, has eight superior Pieces or officers, and eight minor ones which are called Pawns; and, for the purpose of distinction, the Pieces and Pawns of one party are of a different color from those of the other.

A King
A Queen
Two Rooks, or Castles (as they are indiscriminately called)
Two Bishops
Two Knights
And each of these Pieces has his Pawn or Foot-soldier
making in all an array of sixteen men on each side.

On beginning a game, these Pieces and Pawns are disposed in the manner shown on the foregoing diagram. The King and Queen occupy the centre squares of the first or "royal" line, as it is called, and each has for its supporters a Bishop, a Knight, and a Rook, while before the whole stand the Pawns or Foot-soldiers in a row. (To prevent a common error among young players, of misplacing the King and Queen on commencing a game, it is well to bear in mind that at the outset each Queen stands on her own color.) The Pieces on the King's side of the board are called the King's, as King's Bishop, King's Knight, King's Rook; and the Pawns directly in front of them, the King's Pawn, King's Bishop's Pawn, King's Knight's Pawn, and King's Rook's Pawn. The Pieces on the Queen's side are, in like manner, called the Queen's Bishop, Queen's Knight, and Queen's Rook; and the Pawns before them, Queen's Bishop's Pawn, Queen's Knight's Pawn, and Queen's Rook's Pawn.

MOVEMENT OF THE PIECES AND PAWNS,

AND MODE OF CAPTURING AN ADVERSE MAN.

A knowledge of the moves peculiar to these several men is so difficult to describe in writing, and so comparatively easy to acquire over the chess-board, from any competent person, that the learner is strongly recommended to avail himself of the latter means when practicable: for the use, however, of those who have no chess-playing acquaintance at command, the subjoined description will, it is hoped, suffice.

The "Pieces," by which title the eight superior officers are technically designated, in contradistinction to the "Pawns," all take in the same direction in which they move. This act consists in removing the adverse Piece or Pawn from the board, and placing the captor on the square the former occupied. To make this clear, we will begin with the King, and show his mode of moving and of capturing an adverse man.

The King.

The King can move one square only at a time (except in "Castling," which will be explained hereafter), but he can make this move in any direction, forwards, backwards, laterally, or diagonally. He can take any one of the adversary's men which stands on an adjoining square to that he occupies, provided such man is left unprotected, and he has the peculiar privilege of being himself exempt from capture. He is not permitted, however, to move into check, that is, on to any square which is guarded by a Piece or Pawn of the enemy, nor can he, under any circumstance, be played to an adjacent square to that on which the rival King is stationed. Like most of the other Pieces, his power is greatest in the middle of the board, where, without obstruction, he has the choice of eight different squares. At the sides, he may play to any one of five, but when in the angles of the board, three squares only are at his command.

No. 2.

BLACK.

WHITE.

Supposing diagram No. 2 to show the position of the men towards the conclusion of a game, and it being either party's turn to play, he could take the adverse Pawn from the board, and place his King on the square it occupied; and, by doing so, the King would not depart from the order of his march, which, as we have before said, permits him to move one step in every direction. In each of these instances we have placed the Pawn in front of the King, but he would be equally entitled to take it were it standing on any other part of the eight squares immediately surrounding him, always provided it was not sustained or guarded by some other Piece or Pawn.

The Queen.

The Queen is by much the most powerful of the forces. She has the advantage of moving as a Rook, in straight lines, forwards, backwards, and sideways, to the extent of the board in all directions, and as a Bishop, diagonally, with the same range. To comprehend her scope of action, place her alone in the centre of the board; it will then be seen that she has the command of no less than twenty-seven squares, besides the one she stands on. (Diagram No. 3.)

No. 3.

Thus placed in the middle of the board, the range of the Queen is immense. She has here the option of taking any one of eight men at the extremity of the board, on the squares respectively numbered 1, 2, 3, 4, 5, 6, 7, and 8, should her line of march be unobstructed; and if these men were nearer, on any of the intermediate squares, she would be equally enabled to take any one of them at her choice. Like all the other Pieces and Pawns, she effects the capture by removing the man from the board and stationing herself on the vacated square.

The Rook.

No. 4.

BLACK.

WHITE.

The Rook, or Castle, is next in power to the Queen. He moves in a straight line, forwards, backwards, or sideways, having a uniform range, on a clear board, of fourteen squares, exclusive of the one he occupies.

The Rook has the same power in taking as the Queen, forwards, backwards, and sideways, but he cannot, like her, take any man diagonally.

For example, place the Rook in the centre of the board, and an opposing man on each of the squares numbered, and the Rook has the power of taking any one of the four; and he has the same power if the Pieces are one or two squares closer to him, or immediately surrounding him, in the direction indicated by the four figures. (See Diagram No. 4.)

The Bishop.

The Bishop moves diagonally forwards or backwards, to the extent of the Board. It follows, therefore, that he travels throughout the game only on squares of the same color as the one on which he stands when the game begins, and that each player has a Bishop running on white squares, and one on black squares. When placed on a centre square of a clear board, he will be found to have a range of thirteen squares.

No. 5.

The Bishop takes, as he moves, diagonally, either forwards or backwards, his range extending, on unobstructed squares, to the extent of the diagonal line on which he travels. (See Diagram No. 5.)

The Knight.

The action of the Knight is peculiar, and not easy to describe. He is the only one of the Pieces which has the privilege of leaping over another man. The movements of the others are all dependent on their freedom from obstruction by their own and the enemy's men. For example, when the forces are duly ranged in order of battle before the commencement of the game, the Knight is the only one of the eight capital Pieces which can be played before the Pawns are moved—King, Queen, Bishop, and Rook are all hemmed in by the rank of Pawns, which they cannot overleap; but the Knight, having the liberty of springing over the heads of other men, can be brought into the field at once. His move is one square in a straight line, and one in an oblique direction; or it may be perhaps better understood by saying that he moves two squares in a straight line, and one in a side direction.

No. 6.

BLACK.

WHITE.

His power and method of taking an opponent's man will be seen from the diagram (No. 6) on page 14.

In this situation, in the centre of the board, he would have the power of taking any one of the men stationed on the squares numbered, by removing the man and placing himself on the vacant square.

The Pawn.

The Pawn moves only one square at a time, and that straight forward, except in the act of capturing, when it takes one step diagonally to the right or left file on to the square occupied by the man taken, and continues on that file until it captures another man. It may, however, for its first move advance two steps, provided no hostile Pawn commands the first square over which he leaps, for, in that case, the adverse Pawn has the option of taking him in his passage, as if he had moved one step only. A Pawn is the only one of the forces which goes out of his direction to capture, and which has not the advantage of moving backwards; but it has one remarkable privilege, by which, on occasions, it becomes invaluable, whenever it reaches the extreme square of the file on which it travels, it is invested with the title and assumes the power of any superior Piece, except the King, which the player chooses. From this circumstance it frequently happens that one party, by skilful management of his Pawns, contrives to have two, and sometimes even three Queens on the board at once, a combination of force which of course is irresistible.

As we before observed, the Pawn is the only man which captures in a direction different from his line of march. Suppose, at the opening of the game, White begins by playing King's Pawn to King's fourth square (see the article on Notation), Black may reply in the same manner with King's Pawn to King's fourth square, and neither Pawn can do more than remain an obstruction to the onward march of the other, but if Black answer instead with King's Bishop's Pawn to Bishop's fourth, or as in the diagram, with Queen's Pawn to Queen's fourth, then White, if he choose, may take the adverse Pawn from the board and place his own in its stead.

THE NOTATION ADOPTED TO DESCRIBE THE MOVES OF THE MEN.

There is no portion of an elementary work on Chess of so much importance to the learner, and none which requires more resolute mastering than this.

The notation may be called the language of the game and a knowledge of it is absolutely indispensable to every one who is himself ambitious of excelling, or who is desirous of appreciating the excellencies of other players.

Having marshalled the men in battle order, as shown in the first diagram, you will observe that each party has two ranks of men, on the first of which stand the superior Pieces, and on the next the eight Pawns. The eight squares which compose the first rank are each distinguished by the name of the Piece which occupies it when the men are first arranged. There are, therefore, the King's square, the King's Bishop's square, King's Knight's square, and King's Rook's square, and in like manner, the Queen's square, Queen's Bishop's square, Queen's Knight's and Queen's Rook's squares. The files, that is, the row of squares running from top to bottom of the board, are also named by the Pieces occupying the first square in each file. Thus each of the superior officers has a file or row of eight squares running from his end of the board to the corresponding Piece of the enemy, and every one of these eight squares takes its name from such officer.

Bear in mind that White names every square on the board, in accordance with its relative position to one of his eight Pieces, and that Black does the same. Hence it follows that Black's first squares are White's eighth, and vice versâ.

Before proceeding further, it will be desirable for the student to familiarize himself with the respective moves of the Pieces, names of the squares, &c. A very little practice will enable him to do so, especially with the aid of any friend acquainted with them. He should, in the first place, accustom himself to the setting up the men in order of battle; after a few repetitions of the process, and comparing their position with diagram No. 1, he will soon have no difficulty whatever in arranging them correctly without referring to the book. It will then be well to clear the board of all but a single Piece, and practise with that until perfect in its movements; another, and then another, may be added, until the action of every one is as familiar as the alphabet.

Suppose, as a first exercise, you begin by placing your Queen on her square (i.e., her first square), then play her to Q's 5th square, then (diagonally, observe) to Q. Rook's 8th square, then to King's Rook's 8th square, then to Q. R's square, and then home again to her square. It is proper to mention that the directions for moving a Piece are not usually printed in full, and that, according to the modern abbreviations in the present and other chess-books, these several instructions would be given thus:—

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.

In exemplification of the importance of castling, to escape from an attack, and to retort one on the adversary, see, presently, the diagram No. 8 (p. 24).

Check and Checkmate.—The King is said to be in check when he is attacked by any Piece or Pawn, for it being a fundamental law of chess that the King can never be taken, whenever any direct attack upon him is made, he must be warned of his danger by the cry of check, and the player is then compelled either to remove his King out of check, or 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 should be resigned as a drawn battle. And 6th. When one of the Kings is stalemated.

En Prise.—When a Piece or Pawn is in a situation to be taken by the enemy, it is said to be en prise. To put a piece en prise, is to play it so that it may be captured.

The Exchange.—When a player gains a Rook for a Bishop or a Knight, it is termed winning the exchange.

False Move.—Any illegal move, such as castling when the King has been moved or is in check, moving a Rook diagonally, or a Bishop like a Knight, is called a false or an "impossible" move.

Fool's Mate.—This is the simplest of all checkmates, being accomplished in two moves in the following manner:—

WHITE.	BLACK.
1. K. Kt. P. to K. Kt's 4th.	1. K. P. to K's 4th.
2. K. B. P. to K. B's 4th.	2. Q. to K. R's 5th, checkmate.

It cannot possibly be given by the first player.

Forced Move.—When a player has one only legal move at command, it is said to be a forced move.

Gambit.—This word is derived from an Italian phrase in wrestling, and signifies a movement by which the adversary is tripped up. In chess, this is attempted by the first player putting a Pawn en prise of the enemy early in the game, by which he is enabled more rapidly and effectually to develope his superior Pieces. There are several gambits, but the most important, and one which includes many others, is the King's gambit, commenced as follows:—

WHITE.	BLACK.
1. K. P. to K's 4th.	1. K. P. to K's 4th.
2. K. B. P. to B's 4th.	2. P. takes K. B. P.

The Pawn offered by the first player here at his second move is called the Gambit Pawn, and when taken by the adversary the opening becomes a gambit.

The varieties of the gambits are often designated by the names of the players who invented or first brought them into vogue—as the Muzio gambit, the Salvio gambit, the Allgaier gambit, the Lopez gambit; while others obtain their names from the opening moves of the first player, as the King's Bishop's gambit, which begins thus:—

WHITE.	BLACK.
1. K. P. to K's 4th.	1. K. P. to K's 4th.
2. K. B. P. to B's 4th.	2. P. takes P.
3. K. B. to Q. B's 4th.

and is so called because the K's Bishop is played out at the 3d move instead of the K's Knight.

There is also the Queen's gambit, of which the opening moves are—

WHITE.	BLACK.
1. Q. P. to Q's 4th.	1. Q. P. to Q's 4th.
2. Q. B. P. to B's 4th.	2. P. takes P.

The gambits are the most brilliant and animated of all the openings, full of hair-breadth 'scapes and perilous vicissitudes, but affording an infinitude of beautiful and daring combinations.

"Giuoco Piano," a solid and instructive modification of the King's Knight's game, is safe and for drawing games generally practised by the leading players. The opening moves are:

WHITE.	BLACK.
1. P. to K's 4th.	1. P. to K's 4th.
2. K. Kt. to B's 3d.	2. Q. Kt. to B's 3d.
3. K. B. to Q. B's 4th.	3. K. B. to Q. B's 4th.

To Interpose.—When the King is checked, or any valuable Piece in danger from the attack of an enemy, you are said to interpose a man when you play it between the attacked and attacking Piece.

Isolated Pawn.—A Pawn which stands alone, without the support and protection of other Pawns, is termed an isolated Pawn.

J'adoube.—A French expression, signifying "I arrange," or "I replace," which is used by a player when he touches a man merely to adjust its position on the board, without intending to play it. (See the 7th law.)

Minor Pieces.—The Bishop and Knight, in contradistinction to the Queen and Rook, are called Minor Pieces.

The Opposition.—A player is said to have the opposition when he can place his King directly in front of the adverse King, with only one square between them. This is often an important advantage in ending games.

Party.—From the French partie. Frequently used by modern writers instead of the word "game."

Passed Pawn.—-A Pawn is said to be a passed one when the adversary has no Pawn to obstruct its march on the same file, or on either of the next files to the right or left.

Pion Coiffé, or Marked Pawn.—This is a description of odds but rarely given, and only when there is a vast disparity between the skill of the players. It consists in one party placing a cap or ring on one of his Pawns, and undertaking to checkmate his opponent with that particular Pawn. He is not allowed to Queen the Pawn, and if he loses it, or happens to checkmate his opponent with any other man, he forfeits the game. The Pawn usually capped is the King's Knight's, because it can be more readily and effectually surrounded by protecting Pieces.

To Queen a Pawn, or to advance a Pawn to Queen.—When a player has contrived to advance a Pawn to the eighth or last square of the file, it assumes the rank and power of a Queen, or of any other Piece he chooses, and he is then said to have queened his Pawn. (See the 21st law.)

Scholar's Mate.—A checkmate occasionally given at the opening of a game by a practised player to one but little tutored in the science. The following are the moves:—

WHITE.	BLACK.
1. P. to K's 4th.	1. P. to K's 4th.
2. K. B. to Q. B's 4th.	2. K. B. to Q. B's 4th.
3. Q. to K. R's 5th.	3. Q. P. one.
4. Q. takes K. B. P., giving checkmate.

Smothered Mate.—A checkmate which is sometimes given by the Knight when the adverse King is hemmed in, or smothered, by his own forces. (See diagram No. 12.)

Stalemate.—When one party has his King so circumstanced that, not being at the moment in check, he cannot play him without going into check, and at the same time has no other Piece or Pawn to move instead, he is said to be stalemated, and the game is considered drawn. (See diagram No. 13.)

Taking a Pawn en Passant, or in Passing.—It has been shown before, in speaking of the action of the Pawn, that he is limited in his march to one square forward at a time, when not capturing, and one square forward diagonally, either to the right or left, when he takes an adversary, but that he has the privilege, on being first played in the game, to advance two squares, unless in so doing he pass a square which is attacked by a hostile Pawn; in which case the opponent may, at his option, permit him to make the two steps forward, and there remain, or may capture him in his passage in the same way as if he had moved but one step.

No. 8.

BLACK.

WHITE.

In this situation the white King is threatened with what is called "a discovered check," that is, his opponent, by removing the Bishop, would discover check from the Queen, a proceeding in the present instance, which would speedily involve the loss of the game to White. Not being at the moment in check, however, and having moved neither King nor Rook, and there being no intervening Piece between the King and his own Rook, White is enabled to castle, giving check to the adverse King at the same time, and win the game easily, for Black has no square to which he can move his King without going into check, and is consequently obliged to interpose his Q. at K. B's second, or K. B's third square, in either case being checkmated in two more moves, as you will soon be able to see.

Checkmate.

No. 9.

WHITE.

The above position represents the appearance of the forces on each side towards the end of a game, and will assist to explain the application of two or three of the technical terms described in the present section, as well as to exhibit the King in a situation of checkmate. You already understand that the moves at chess are played by each party alternately; in this case it is White's turn to play, and he will checkmate his antagonist in two moves. Place the chess-men on your board exactly in the order they stand in the diagram; having done this, suppose yourself to be playing the White men, and take the Black King's Pawn with your Queen, in the manner before shown, i.e., by taking the Pawn from the board and stationing your Queen on the square it occupied. By this act, you not only take his Pawn, but you attack his King, and must apprise him of his danger by calling "check." He has now two ways only of parrying this check. It is clear he cannot move his King, because the only two squares to which he could move without going into check are occupied by his own men; he is forced then either to take the Queen with his K. B's Pawn, or to interpose the Bishop at King's second square. If he take the Queen with his K. B's Pawn, you must reply by playing your King's Bishop (which you will know by the color of the diagonal on which he travels) to K. Kt's sixth square, crying "check." Examine the position attentively, and you will find that Black has no square to which he can move his King, the only vacant one being attacked by your Queen's Bishop, that he has nothing wherewith to take the Bishop that has given check, and neither Piece nor Pawn with which to interpose between it and his King, and that consequently, he is not only checked, but checkmated. In like manner, if, at his first move, instead of capturing your Queen, he interpose his Bishop at King's second square, you immediately take the Bishop with your Queen, who is protected by her Bishop, and say "checkmate."1

Perpetual Check.

The diagram on page 28 will enable you to understand what is meant by perpetual check as well as the most elaborate arrangement of the men could do. Place the men on your chess-board according to the diagram, suppose yourself to be playing the white Pieces, and that it is your turn to move. Your adversary, you will observe, has the advantage in point of force, but this is counterbalanced by the situation, which enables you to draw the game. To do this, you must first play your Queen to one of the three squares where she will check the King, i.e., to K's 4th, Q's 5th, or Q. B's 6th; it is indifferent which, say, therefore, Q. to K's 4th (check). Black has no option, his King cannot move, he must interpose his Queen. If now you were to take the Queen you would lose the game, on account of his two Pawns; but instead of doing so, you play the Queen to King's 8th sq, giving check. The black Queen must again interpose; you repeat the check at K's 4th, Black can only parry it with his Queen, and you may persist in giving the same two checks, ad infinitum. In such cases, the game is resigned as "drawn by perpetual check."

No. 11.

Smothered Mate.

This is a familiar example of smothered mate, which you will find can be effected by no other Piece than the Knight. White first move is, Queen to her 5th square checking. Black is obliged to retreat his King to the R's sq., because, were he to play him to his B's sq., the Q would checkmate at once. Upon the King retiring, White gives check with his Kt. at K. B's 7th; this brings the King back again to Knight's sq., and affords to White an opportunity of giving double check, which he does by moving the Knight to K. Rook's 6th, checking with both Q. and Knight; as before, the King must go to Rook's sq.; and now follows a beautiful move—White plays his Queen down to K. Kt's 8th (next square to the Black King), giving check; the King cannot take on account of the Knight; he is compelled, therefore, to capture with his Rook, and the Knight then gives the smothered mate at K. B's 7th square.

Stalemate. (See Diagram on page 30.)

Here you observe that White has the great advantage of a Queen against a Rook; but with all this, and the move to boot, it is impossible for him to do more than draw the game. It is evident that he cannot move his Queen from the front of his King on account of exposing him to check with the Rook. If he move his King, Black takes the Queen, and the game is drawn. And lastly, if he take the Rook with his Queen, he places the adverse King in the position before described of stalemate.

ON THE RELATIVE VALUE OF THE CHESS FORCES.

An attempt to establish a scale of powers whereby the relative values of the several men could be estimated with mathematical exactitude, although it has frequently engaged the attention of scientific minds, appears to be an expenditure of ingenuity and research upon an unattainable object. So ever varying, so much dependent on the mutations of position which every move occasions, and on the augmented power which it acquires when combined with other forces, is the proportionate worth of this with that particular man, that it would seem to be beyond the reach of computation to devise a formula by which it can be reckoned with precision. But still an approximation to correctness has been made, and the result arrived at gives the following as the ultimate respective values:—

Pawn	= 1.00
Knight	= 3.05
Bishop	= 3.50
Rook	= 5.48
Queen	= 9.94

The King, from the nature of the game, which does not admit of his being exchanged or captured, is invaluable, and he is not, therefore, included in the calculations.

The Pawn, it is seen, is the least valuable of all the men, the Knight being worth at least three Pawns.

The Bishops and Knights are practically considered of equal value, although there is a difference in the estimate here given.

A Rook is of the value of five Pawns and a fraction, and may be exchanged for a minor Piece and two Pawns. Two Rooks may be exchanged for three minor Pieces.

The Queen is usually reckoned equal, in average situations, to two Rooks and a Pawn, but towards the end of a game she is hardly so valuable as two Rooks.

These comparative values may be of service to the student in general cases of exchanging men, but he will find in practice the relative worth of his soldiers is modified by so many circumstances of time, opportunity, and position, that nothing but experience can ever teach him to determine accurately in every case "which to give up and which to keep."

Whenever the word "Umpire" is used herein, it stands for any Committee having charge of Matches or Tournaments, with power to determine questions of chess-law and rules; or for any duly appointed Referee, or Umpire; for the bystanders, when properly appealed to; or for any person, present or absent, to whom may be referred any disputed questions; or for any other authority whomsoever having power to determine such questions.

When the word "move" is used it is understood to mean a legal move or a move to be legally made according to these laws.

When the word "man" or "men" is used, it is understood that it embraces both Pieces and Pawns.

THE CHESS-BOARD AND MEN.

The Chess-board must be placed with a white square at the right-hand corner.

If the Chess-board be wrongly placed, or if there is a deficiency in number, or a misplacement of the men, at the beginning of the game, the game shall be annulled, provided the error is discovered before the second player makes four moves.

FIRST MOVE AND COLOR.

The right of first move must be determined by lot.

The right of first move shall alternate, whether the game be won, lost or drawn.

Whenever a game shall be annulled, the party having the move in that game shall have it in the next game. An annulled game must be considered, in every respect, the same as if it had never been begun.

CONCESSIONS.

The concession of an indulgence by one player does not give him the right of a similar or other indulgence from his opponent.

ERRORS.

If, during the course of the game, it be discovered that any error or illegality has been committed in the moves of the pieces, the moves must be retraced, and the necessary correction made, without penalty.

If the moves cannot be correctly retraced the game must be annulled.

If a man be dropped from the board and moves made during its absence, such moves must be retraced and the man restored. If this cannot be done, to the satisfaction of the Umpire, the game must be annulled.

CASTLING.

The King can be Castled only:—

When neither the King nor the Castling Rook has been moved, and

Where the King is not in check, and

Where all the squares between the King and Rook are unoccupied, and

Where no hostile man attacks the square on which the King is to be placed, or the square he crosses.

In Castling, the King must be moved first, or before the Rook is quitted. If the Rook be quitted before the King is touched, the opposing player may demand that the move of the Rook shall stand without the Castling being completed.

The penalty of moving the King prohibits Castling.

EN PASSANT.

Taking the Pawn "en Passant," when the only possible move, is compulsory.

PROMOTING THE PAWN.

A Pawn reaching the eighth square must be at once exchanged for any piece of its own color (except the King) that the player of the Pawn may elect.

CHECK.

No penalty can be enforced for an offence committed against these rules in consequence of a false announcement of "check." When check is given it is not obligatory to announce the check.

"J'ADOUBE."

"J'adoube," "I adjust," or words to that effect, cannot protect a player from any of the penalties imposed by these laws, unless the man or men touched, obviously need adjustment, and unless such notification be distinctly uttered before the man, or men, be touched, and only the player whose turn it is to move is allowed so to adjust.

The hand having once quitted the man, but for an instant, the move must stand.

Men overturned or displaced accidentally may be replaced by either player, without notice.

A wilful displacement, or overturning of any of the men, forfeits the game.

PENALTIES.

Penalties can be enforced only at the time an offence is committed, and before any move is made thereafter.

A player touching one of his men, when it is his turn to play, must move it. If it cannot be moved he must move his King. If the King cannot move, the offender must move a man selected by his opponent.

For playing two moves in succession the adversary may elect which move shall stand.

For touching an adversary's man, when it cannot be captured, the offender must move his King. If the King cannot move, the offender must move a man selected by his opponent. But if the man touched can be legally taken, it must be captured.

For playing a man to a square to which it cannot be legally moved, the adversary, at his option, may require him to move the man legally, or to move the King. If the latter penalty be exacted, and the King cannot legally be moved, the offender must move any piece designated by the opposing player.

For illegally capturing an adversary's man, the offender must move his King, or legally capture the man, as his opponent may elect. If neither is possible, the offender must move a man selected by his opponent.

For attempting to Castle illegally, the player doing so, must move either the King or Rook, as his adversary may dictate.

For touching more than one of the player's own men, he must move either man that his opponent may name.

For touching more than one of the adversary's men, the offender must capture the one named by his opponent, or if either cannot be captured, he may be required to move the King or capture the man which can be taken, at the adversary's option; or, if neither can be captured, then the King must be moved.

A player moving into check may be required, by the opposing player, either to move the King elsewhere, or to move some other piece designated by the opposing player.

For discovering check on his own King, the player must either legally move the man touched, or move the King at his adversary's option. In case neither move can be made he must move a piece designated by his adversary.

While in check, for touching or moving a man which does not cover the check, the player may be required to recover with another piece, or move the King, as the opposing player may elect.

ADJOURNED GAME.

Upon a game being adjourned, the player whose turn it is to move shall seal his move. Sealing a move consists in writing it legibly on a piece of paper which shall remain in the keeping of a third party during the adjournment.

Upon the resumption of an adjourned game the position existing at the time of adjournment shall be set up and the sealed move made on the board.

If the position existing at the time of adjournment cannot be ascertained the game shall be annulled.

If upon opening a sealed move the record cannot be interpreted as expressing a legal move, the offending player may be required to move his King, or, if the King cannot legally be moved, a piece designated by his opponent. If the record can be interpreted as expressing either of two moves, the offender shall make the one selected by his opponent.

DRAWN GAMES.

A game is drawn—

(a) When the players agree to treat it as drawn.

(b) Upon the proof by either player that fifty moves have been made on each side without a piece being captured.

(c) When either player claims a draw upon his turn to play, and proves that the existing position has occurred at least twice before during the game.

(d) When either player claims a draw and demonstrates that he can subject the opposing King to an endless series of checks.

(e) When a stale-mate occurs.

TIME LIMIT.

The penalty for exceeding the time limit is the forfeiture of the game.

It shall be the duty of each player, as soon as his move be made, to stop his own register of time and start that of his opponent, whether the time be taken by clocks, sand-glass, or otherwise. No complaint respecting an adversary's time can be considered, unless this rule be strictly complied with. But nothing herein is intended to affect the penalty for exceeding the time limit as registered.

ABANDONING THE GAME.

If either player abandon the game by quitting the table in anger, or in an otherwise offensive manner; or by momentarily resigning the game; or refuses to abide by the decision of the Umpire, the game must be scored against him.

If a player absent himself from the table, or manifestly ceases to consider his game, when it is his turn to move, the time so consumed shall, in every case, be registered against him.

DISTURBANCE.

Any player wilfully disturbing his adversary shall be admonished; and if such disturbance be repeated, the game shall be declared lost by the player so offending, provided the player disturbed then appeals to the Umpire.

THE UMPIRE.

It is the duty of the Umpire to determine all questions submitted to him according to these laws, when they apply, and according to his best judgment when they do not apply.

No deviation from these laws can be permitted by an Umpire, even by mutual or general consent of the players, after a match or tournament shall have been commenced.

The decision of the Umpire is final, and binds both and all the players.

RULES FOR PLAYING THE GAME AT ODDS.

I. In games where one player gives the odds of a piece, or "the exchange," or allows his opponent to count drawn games as won, or agrees to check-mate with a particular man, or on a particular square, he has the right to choose the men, and to move first, unless an arrangement to the contrary is agreed to between the combatants.

II. When the odds of Pawn and one move, or Pawn and more than one move, are given, the Pawn given must be the King's Bishop's Pawn when not otherwise previously agreed on.

III. When the odds of two or more moves are given, the player receiving the odds shall begin the game with these moves, but may not, in making them, advance any piece beyond his fourth rank.

IV. When a player gives the odds of a Rook he may move his King as though to castle with the Rook given, provided the square of the missing Rook has been unoccupied throughout the game, and provided the ordinary conditions as to squares and the King are complied with.

V. When the odds of a Pawn, Knight, Bishop, or Rook, are given, it is understood that the King's Bishop's Pawn, or the Queen's Knight, Queen's Bishop or Queen's Rook, is intended unless special agreement to the contrary is made.

1. We append a diagram here, showing a position which has frequently been misapprehended by unpractised players.

By inspecting the diagram it will be seen that the White King is in check of the Black Queen. By the simple move of the White Rook to K. Kt's 5th square, checking the Black King, and at the same time discovering check by the White Queen, Black is checkmated, although having by far the strongest force of men. We give the position to show that any Piece or Pawn, although employed in covering a check of its own King, has nevertheless the power to check the adverse King.
