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.

5. KtxP
Black can now get Whiteβs KP by playing Q-K2, and moreover exchange Whiteβs valuable Bishop. Instead of the move in the text it is advisable to retire the Bishop to R4 or B4, or else to play 5. KtxKt, PxKt; 6. P-K5, PxKt; 7. PxKt. Black would then play QxP and not PxQPch, as the latter move allows White to develop quickly, and Black has no time to castleβe.g. 8. BxP, QxP; 9. Castles, B-K2; 10. B-B3, followed by R-K1.

Here KtxB was essential, followed by QxP, freeing the Bishop. After 7. KtxKt, QxPch; 8. Q-K2, QxQch; 9. KxQ, Kt-Q4 (10. P-B4, P-QR3), Black completes his development a little later (10. R-K1, P-KB3; 11. K-B1ch, K-B2), but after the exchange of Queens there is not much to fear from an immediate attack, and the value of the two Bishops soon asserts itself. In a match game Ed. Lasker-Cole (London, 1913) the continuation was 12. P-Q4, P-QR3; 13. Kt-B3, KtxKt; 14. PxKt, P-Q4. Here the doubled pawn is a disadvantage, in that the pawn at B2 is immobile, and constantly liable to be attacked by B-B4. P-Q3 was the better move.
7. Castles KtxKt
Now KtxB was no longer possible. After KtxQKt there would be threats of KtxBP as well as of R-K1 and P-Q3. The game is almost lost for Black at this stage, as the King cannot escape the impending attack on the K file by castling.

Black being behind with his development is already threatened by sacrificial combinations. If he takes the Bishop he loses by 15. B-Kt5ch, K-B1; 16. Q-Q8ch!, BxQ; 17. R-K8 mate, or l5. β¦ P-B3; 16. BxPch, and so on.

Here Black might have castled on the Queenβs side, but R-Q1 would have had much the same sequel as in the actual game.
17. B-K5 Q-R3
18. R-Kt3 B-KB1
A sorry retreat. But after Q-Q7, which may have been Blackβs original intention, White plays R-KB1, threatening B-KB4.
19. R-Q1
This move completes Whiteβs development, and only seems to give Black a chance of castling. However, Black has no satisfactory continuation.

Three Knightsβ Defence.
1. P-K4 P-K4
2. Kt-KB3 Kt-QB3
3. Kt-B3 B-Kt5
4. Kt-Q5
Developing another piece by B-Kt5 or B4 would be more in accordance with principle.
4. β¦ B-K2
There was a threat of KtxB and KtxP. If Black plays P-Q3, the B must retire all the same after 5. B-Kt5. It seems best to retire the B to K2 rather than to B4 or R4, because there remains the threat of a pin subsequently by B-KKt5, which might become serious with the Knight at Q5.
5. B-B4 Kt-B3
6. P-Q3 P-Q3
7. KtxB QxKt
8. P-B3 P-KR3
The KKt is to support the advance of P-Q4 subsequently, and that is why Black does not want to allow it to be pinned. This is sound strategy, since White has exchanged his QKt, which from B3 prevents P-Q4 in the ordinary way.
9. B-K3 Castles
10. Q-Q2 B-K3

The first mistake. B-QKt5 should be played to retard P-Q4.

13. PxP
The second mistake. Unimportant as it seems, it leads to the loss of the game. White did not defend the pawn by Q-B2, because it would have proved 10. Q-Q2 to have been a lost move. But giving up the centre is a far greater evil. Black now commands his Q5 and KB5, and this enables him to start an attack to which there is no defence. The game shows conclusively how important it is to maintain the centre.

to prevent P-K5, which would now be countered by PxP and Q-B4. However, as P-K5 cannot be prevented permanently, and the Q must move in any case, Q-B2 would have been the better move, as there the Queen cannot be molested by a Rook.

Blackβs game is beautifully developed, whilst White cannot make a combined effort. The Black Rooks are particularly well placed, and threaten to take an effective part in the attack in various ways. All this is the outcome of White losing the centre.
20. P-KKt3
Though this prevents Kt(Q 4)-B5, it weakens KB3, which is all the more serious as Black threatens to open the file by P-B5.

If now White refrains from taking the pawn, Black plays P-QR4!

KKt-Q2 is better, because it would support the advance of P-QB4 and also be of use eventually in an attack on Whiteβs centre by P-KB3. The text move allows the exchange of two minor pieces, which can only be to Whiteβs advantage, as Black cannot get his QB into play, and is for a long time practically a piece down.

So far the game is easy to understand in the light of the remarks made on page 44, when treating of the openings. The continuation shows in an instructive fashion that Whiteβs attack is the more effective, being directed against the Kingβs side.
17. P-B5! KPxP
This sacrifice of a pawn in conjunction with a second sacrifice on the next move, produces a combination of rare beauty.
18. P-Kt4!! PxP
If Black did not capture White would. In either case the storming of the position by pawns achieves its object and the lines of attack are free for the pieces.
19. Kt-Kt5 P-Kt3
Now that White has made an opening for himself at KB6, the rest is easy. 19. β¦ P-R3 is of no avail. The sequel might have been: 20 Kt-R 7, KR-Q1; 21 Kt-B6ch, after which White wins after either PxKt; 22 QxP, or K-R1 KtxP.
20. R-B6 K-Kt2
Black gets no breathing space. If P-R3, then 21 BxP.

If the Queen recaptures, White obtains too great an advantage in development, and therefore Black submits to the doubling of his pawns. It is doubtful if this means a handicap, although the Kingβs side gets broken up. For Black keeps his two Bishops, a powerful weapon, unless White succeeds in developing swiftly an attack on the Kingβs side. The present game is instructive and shows the chances afforded to both sides by the position brought about by the exchange at KB6.
6. KtxP P-KB4
As the KB obtains a long diagonal at Kt2, this advance is justified. Otherwise there would be strong objections to it, as the pawn is likely to be subjected to attack, and apart from that, it gives up command of Blackβs K4.
7. Kt-QB3
Kt-Kt3 would seem more natural, firstly, because Black has weaknesses on the K side, and White will need his pieces for attack in that quarter, and secondly, because the QP ought to be supported by P-B3, as Black will attack it by B-Kt2.
7. β¦ B-Kt2
8. Kt-B3 Castles
9. B-B4
If now the Knight were at Kt3, White could play P-B3 and BQ3. This is the proper place for the B, which might obtain an open diagonal after P-KKt4.
9. β¦ Kt-B3
10. Kt-K2 Kt-R4
11. B-Q3 P-B4
12. P-B3 P-QB5
P-Kt3 seems preferable, as the text move releases the hold on Whiteβs Q4. The isolated pawn resulting after 13. PxP is not to be feared, as the B at Kt2 would have greater efficiency (QR-Kt1), and White would not be so firmly established in the centre.
13. B-B2 P-Kt4
14. Q-Q2
There now ensues an interesting struggle. White builds up an attack with Q and both Knights and eventually the B (P-KKt4). If Black can manage to play his King into safety at R1 in time, and then occupies the Kt file with his Rooks, he would have the better of it, his pieces having by far the greater range of action.
