1. ... K-Q3
2. P-B3 K-B3
3. K-B4 and wins.
This settles all typical end-games of King and pawn against King. There is, however, one exception to the rules set out, namely, when a ROOK'S PAWN is concerned. Here the isolated King always succeeds in drawing if he can reach the corner where the pawn has to queen, for he cannot be driven out again. The Rook's pawn affords another opportunity for the weaker side to draw. Diagram 55 will illustrate this, and similar positions are of frequent occurrence in practice. Here Black draws with 1. ... K-B5. As he threatens to capture the pawn, White must play 2. P-R4. Then after the reply K-B4, White is still unable to cut the opponent off from the corner with K-Kt7, as the loss of the pawn is still threatened through K-Kt5. And after 3. P-R5 Black attains the position which is typical for this end-game, namely the opposition against the King on the Rook's file. The latter cannot escape without giving up the contested corner, and the game is drawn. 3. ... K-B3; 4. K-R7, K-B2; 5. K-R8, K-B1; 6. P-R6, K-B2; 7. P-R7, K-B1: and White is stalemated.

II. NOTATION
A special notation has been adopted to make the study of games and positions possible, and it is necessary for students of the game to become thoroughly conversant with it. The original and earliest notation is still in use in English, French, and Spanish speaking countries. It is derived from the original position in the game, in that the squares take the names of the pieces which occupy them. Thus the corner squares are called R 1 (Rookβs square or Rookβs first), and to distinguish them from one another QR1 or KR 1 (Queenβs or Kingβs Rookβs square). The squares immediately in front are called QR2 or KR2. A distinction is made between White and Black, and Whiteβs R 1 is Blackβs R 8, Blackβs R 2 is Whiteβs R 7, Whiteβs K B 3 is Blackβs KB6, and so on. K stands for King; Q for Queen; B for Bishop; Kt for Knight; R for Rook; and P for Pawn. In describing a capture, only the capturing and the captured pieces are mentioned, and not the squares.
When confusion is possible, it is customary to add whether Kingβs side or Queenβs side pieces are concerned, e.g. KRx Q Kt. In this notation it is necessary to bear in mind which Kt is the Q Kt, which R is the KR. This becomes increasingly difficult as the game goes on and pieces change their places. Many sets of chessmen have one Rook and one Knight stamped with a special sign, to show they are Kingβs side pieces. This is not necessary in the case of Bishops: a white KBis always on white squares, a white QBon black squares.
A more modern notation is the algebraic notation, which has been adopted in most countries. It has the advantage of being unmistakably clear, and also more concise. Here the perpendicular lines of squares (called files) are named with the letters a-h, from left to right, always from the point of view of White, and the horizontal lines of squares (called ranks) with numbers 1-8 as before, only with the distinction that the rank on which the White pieces stand is always called the first; thus the square we named Whiteβs QB2 or Blackβs QB7 is now called c2 in both cases. Blackβs QB2 (Whiteβs QB7) is always c7. In capturing, the square on which the capture takes place and not the piece captured is noted, for the sake of uniformity. In the case of pawn moves, the squares only are noted.
OβO stands for castles on the Kingβs side; OβOβO stands for castles on the Queenβs side; : or x stands for captures; + for check.
In the following opening moves, both notations are used for the purpose of comparison:
1. P-Q 4 P-Q4 1. d4 d5
2. P-QB4 P-K3 2. c4 e6
3. Kt-QB3 P-QB4 3. Ktc3 c5
4. PxQP KPxP 4. cd: ed:
5. P-K4 QPxP 5. e4 de:
6. P-Q5 Kt-KB3 6. d5 Ktf6
7. BβKKt5 B-K2 7. Bg5 Be7
8. K Kt-K2 Castles 8. Ktge2 OβO
In most books in which the algebraic notation is used, both squares of a move are written out for the benefit of the student. The moves above would then look like this:
1. d2-d4 d7-d5
2. c2-c4 e7-e6
3. Ktb1-c3 c7-c5
4. C4 x d5 e6xd5
5. e2-e4 d5xe4
6. d4-d5 Ktg8-f6
7. Bc1-g5 Bf8-e 7
8. Ktg1-e2 OβO
To conclude: I will give the denomination of the pieces in various languages:

THE mental development of the chess player is a gradual struggle from a state of chaos to a clear conception of the game. The period required for such development largely depends upon the special gifts the learner may possess, but in the main the question of methods predominates. Most beginners do not trouble very much about any particular plan in their study of chess, but as soon as they have learnt the moves, rush into the turmoil of practical play. It is self-evident that their prospects under such conditions cannot be very bright. The play of a beginner is planless, because he has too many plans, and the capacity for subordinating all his combinations to one leading idea is non-existent. Yet it cannot be denied upon investigation that a certain kind of method is to be found in the play of all beginners, and seems to come to them quite naturally. At first the pawns are pushed forward frantically, because there is no appreciation of the power and value of the pieces. Conscious of the inferiority of the pawns, the beginner does not conclude that it must be advantageous to employ the greater power of the pieces, but is chiefly concerned with attacking the opposing pieces with his pawns in the hope of capturing them. His aim is not to develop his own forces, but to weaken those of his opponent. His combinations are made in the hope that his adversary may not see through them, nor does he trouble much about his opponentβs intentions. When most of his pawns are gone, then only do his pieces get their chance. He has a great liking for the Queen and the Knight, the former because of her tremendous mobility, the latter on account of his peculiar step, which seems particularly adapted to take the enemy by surprise. When watching beginners you will frequently observe numberless moves by a peripatetic Queen, reckless incursions by a Knight into the enemyβs camp, and when the other pieces join in the fray, combination follows combination in bewildering sequence and fantastic chaos. Captures of pieces are planned, mating nets are woven, perhaps with two pieces, against a Kingβs position, where five pieces are available for defence. This unsteadiness in the first childish stages of development makes it very difficult for the beginner to get a general view of the board. Yet the surprises which each move brings afford him great enjoyment.
A few dozen such games are by no means wasted. After certain particular dispositions of pieces have proved his undoing, the beginner will develop the perception of threats. He sees dangers one or two moves ahead, and thereby reaches the second stage in his development.
His combinations will become more and more sound, he will learn to value his forces more correctly, and therefore to husband his pieces and even his pawns with greater care. In this second stage his strength will increase steadily, but, and this is the drawback, only as far as his power of combination is concerned. Unless a player be exceptionally gifted, he will only learn after years of practice, if at all, what may be termed βpositional play.β For that, it is necessary to know how to open a game so as to lay the foundation for a favourable middle game, and how to treat a middle game, without losing sight of the possibilities of the end-game. It is hopeless to try to memorise the various openings which analysis have proved correct, for this empirical method fails as soon as the opponent swerves from the recognised lines of play. One must learn to recognise the characteristics of sound play. They apply to all and any position, and the underlying principles must be propounded in a manner generally applicable. And this brings me to the substance of my subject, round which I will endeavour to build up a system compatible with common sense and logic.
Before I proceed to develop my theme, I shall set down a number of elementary rules which will facilitate the understanding of such simple combinations as occur at every step in chess.
If we ignore the comparatively small proportion of games in which the mating of the opponentβs King is accomplished on a full board, we can describe a normal, average game of chess in the following way. Both sides will employ their available forces more or less advantageously to execute attacking and defensive manoeuvres which should gradually lead to exchanges. If one side or the other emerges from the conflict with some material gain, it will generally be possible to force a mate in the end-game, whilst if both sides have succeeded by careful play to preserve equality of material, a draw will generally ensue.
It will be found a little later that a single pawn may suffice, with some few exceptions, to achieve a victory, and we shall adopt the following leading principle for all combinations, viz. loss of material must be avoided, even if only a pawn. It is a good habit to look upon every pawn as a prospective Queen. This has a sobering influence on premature and impetuous plans of attack.
On the other hand, victory is often brought about by a timely sacrifice of material.
But in such cases the sacrificing of material has its compensation in some particular advantage of position. As principles of position are difficult for beginners to grasp, I propose to defer their consideration for the present and to devote my attention first to such combinations as involve questions of material. Let us master a simple device that makes most combinations easy both for attack and defence. It amounts merely to a matter of elementary arithmetic, and if the beginner neglects it, he will soon be at a material disadvantage.

Diag. 4.
It is Blackβs move, and we will suppose he wishes to play P-K4. A beginner will probably calculate thus: I push on my pawn, he takes with his pawn, my Knight takes, so does his, then my Bishop takes, and so on. This is quite wrong, and means waste of time and energy.
When the beginner considers a third or fourth move in such a combination, he will already have forgotten which pieces he intended to play in the first moves. The calculation is perfectly simple upon the following lines: I play P-K4, then my pawn is attacked by a pawn and two Knights, a Bishop and two Rooks, six times in all. It is supported by a Bishop, two Knights, two Rooks and a Queen, six times in all. Therefore I can play P-K4, provided the six units captured at K4 are not of greater value than the six white units which are recaptured. In the present instance both sides lose a pawn, two Knights, two Rooks, and a Bishop, and there is no material loss. This established, he
