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.

8. Kt-Q2 Q-Kt3
The exchange of Bishops allows White to play Kt-K3, thus avoiding the weakening move P-K Kt3. 9. B-KB4 is answered by P-Q4!.

10. Kt-K3 R-QKt1

To prevent Blackβs P-B4.
At first sight it seems as if the QBP ought to move to B4, as the advance of the QKtP has weakened it. But White dares not allow a Black Knight to settle at Q5.

Black threatens to play K-R1 in order to play P-B4. Whiteβs position would then be very bad, and therefore he rightly decides to anticipate the move, even at the cost of a pawn. In order to gain the QBP Black must waste a number of moves with the Q, and White gains time for a Kingβs side attack. The pawn sacrifice is very promising indeed.
13. β¦ Q-B3
14. Castles QxQBP
15. R-B3
There seem to be many threats here, and the position is a difficult one to fathom. After disentangling his Queen, Black tries very hard to force his P-B4. As soon as he succeeds in this he has a won game, for the open file is available both for defence and counter-attack.

Q-B3 is impossible apart from the fact that it would block the KBP, e.g. 18. β¦ Q-B3; 19. P-K5, PxP; 20. Kt-K4, etc.
19. R-QB2 Q-B3
Now the attack shown in the last note could be answered with Q-R5.
20. Kt-Kt4
Here P-KKt4 could be answered by Kt-Q5, e.g. 21. P-Kt5, Q-Kt3; 22. R-Kt3, P-B4.

This prevents the Rook from occupying the Q file which is about to be opened.

4. Kt-Kt5
This attack may be tempting, as the BP cannot be protected, but it is against that elementary principle which says that no attack should be undertaken in the opening until the minor pieces are mobilised, provided of course that Black also has made sound opening moves. There is every likelihood that the attack in the present instance will lead to nothing. It has taken many years to find the correct reply, but now that it is known, the opening has practically disappeared from master practice. Instead of the move in the text, White can play either P-Q3, leading almost unavoidably to a drawing variation of the Giuoco piano, or Castles which might bring about the Max Lange attack after 4. β¦ B-B4; 5. P-Q4, PxP.
4. β¦ P-Q4
5. PxP Kt-QR4!
This is a typical position in the Two Knightsβ defence. The former continuation 5. β¦ KtxQP has long been abandoned, as the attack that White can initiate by 6. KtxBP, KxKt; 7. Q-B3ch, forcing the Black King to K3, is dangerous though the result is uncertain. The move in the text breaks the attack from the very first, and Black gets the advantage

as he can gain time by attacking the two minor pieces which it should be noted, are unsupported, and in addition obtain a speedy development, worth more than the pawn given up for it.
6. P-Q3
B-Kt5ch is an alternative. The advantage is Blackβs in this case alsoβe.g. P-B3; 7. PxP, PxP; 8. B-K2, P-KR3; 9. Kt-KB3, P-K5; 10. Kt-K5, Q-B2; 11. P-Q4, B-Q3 (or PxP e.p. followed by B-Q3); 12. P-KB4, PxP e.p.; 13. KtxP, Kt-Kt5 or 11. P-B4, B-Q3; 12. P-Q4, PxP e.p.; 13 KtxP, Castles. Black has an easy game and open lines.

A sorry retreat, but the plausible Q-Q2 would be disastrous, e.g. P-K6!; 13. PxP, Kt-K5 and Q-R5ch
12. β¦ B-Kt5ch
Blackβs superior development begins to tell in no uncertain fashion. Now White can neither play 13. B-Q2 on account of BxBch; 14. QKtxB, R-K1, followed by P-K6, nor 13. Kt-B3 on account of BxKt; 14. PXB, P-B3 regaining the pawn and maintaining positional advantage. White has therefore no alternative but P-B3, which weakens his Q3, where a Black Knight soon settles down.

At last White can castle. He can, of course, only castle on the Queenβs side, because his Kingβs side pawns are shattered. Now games in which the Kings castle on different wings are more or less beyond calculation, as pointed out before. On the whole, the player who first attacks wins. But experience has shown that the Queenβs side is more difficult to defend on account of its greater expanse, and this theory is supported by the present game. In addition, Whiteβs development is not completed yet, whilst all the Black forces are ready to strike.

Storming the position with pawns is peculiar to this kind of game. The intention is to break up the opposing pawn position, and to open files for the Rooks. Pawns are cheap in such cases. Open lines for the pieces are the things that matter, and the fewer pawns there are left, the more open lines are available for the attack.
19. PxP Kt-Q6ch
20. K-Kt1 QxP
21. K-R1
The King was not safe on the diagonal. White wishes to push on his Kingβs side pawns (P-B4-B5, and so on). But after PxP e.p. there would be a fatal discovered check by the Black Knight.
22. β¦ QxP
Blackβs advantage becomes more marked. He has recovered his pawn, and for the ensuing attacks on both sides he is better placed, having already two open files for his Rooks.

The position bristles with chances for daring sacrifices. After 25. KtxBP, for instance, Black could play RxKt!; 26. PxR, Kt-Kt5; 27. PxKt, PxP; 28. P-R3 (Q-B4ch?, B-B2), B-B3; 29. K-R2, QxPch; 30. PxQ, RxP mate.

Whiteβs compulsory 25. P-Kt3 has weakened his QB3, and the move in the text is intended to open the diagonal KB3-QB6 for the Black Bishop.

The idea underlying this pawn sacrifice is to open the K file for the Rook. It will be seen that, with correct play, Black manages to castle just in time, and White, though winning back his pawn, has no advantage in position. The opening is seldom played by modern masters.
Instead of the move in the text, White can hardly defend the KP with Kt-B3, as Black simply captures the pawn and recovers his piece by P-Q4, with a satisfactory position. It is even better for Black if White plays 6. BxPch in reply to 5. β¦ KtxP. The capture of Whiteβs KP is far more important than that of the Black KBP, particularly as the White Bishop, which could be dangerous on the diagonal QR2-KKt8, is exchanged, e.g. 6. β¦ KxB; 7. KtxKt, P-Q4; 8. Kt-Kt5ch, K-Kt1! Black continues P-KR3,
