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.

11. Castles P-R5

13. BxKt
White has to capture with the B, in order to exchange the Black Knight if it should play to B4. After 13. KtxKt, B-Q5ch; 14. K-R1, Kt-B4; Whiteβs Knight would not be able to move from K4 on account of the threat: Kt-Kt6ch. Sooner or later, Black would get a deciding advantage by enforcing the exchange of Whiteβs Knight, e.g. 15. Q-K1, Q-K2; 16. R-QKt1, B-Q2; 17. P-QKt3, Castles QR; 18. B-Kt2, QxKt; 19. BxQ, Kt-Kt6ch; 20. QxKt, PxQ; 21. P-KR3, BxP; 22. PxB, RxPch; 23. K-Kt2, R-R7ch; 24. KxP, RxB; or 21. BxB, RxPch, followed by PxB and QR-R1.

White is helpless against the two powerful Bishops.
16. R-K1ch K-B1
Black forfeits his chance of castling, not a great loss under the circumstances. In any case his KR is needed on the Rookβs file, and Black would only have castled on the Queenβs side if at all.
17. Q-B3
Here P-KR3 was essential in order to prevent the further advance of the KRP. The weakness at Kt3 would not have been so serious in the absence of a Black Knight. Now Black forces the advance of Whiteβs KKtP, and the Bishops become immediately effective.

21. QR-B1 K-Kt2

Black must not exchange his valuable Bishop.
23. P-Kt3 KR-K1
24. B-B2
There is no answer to Blackβs threat of doubling the Rooks on the K file. If White plays Q-B2, Blackβs Queen effects an entry at Q6, after which he would double his Rooks, and Whiteβs Bishop cannot be defended. After the text move, Black forces the exchange of his two Rooks for the Queen. Generally speaking, this is no disadvantage, but in consequence of the exposed position of the White King, it means a speedy loss for White.

2. P-Q5 P-Q3
3. P-QB4 P-KKt3

This is not necessary. Black could hardly exchange his B for the Kt; the weakness at his KB3 and KR3 would become too serious a disadvantage.
5. β¦ P-K3
6. P-K4 PxP
7. KtxP!
In view of the fact that Blackβs position after BP or KPxP would be very promising, as all his pieces would be easy to bring into play, White decides upon the sacrifice of a pawn, in order to further his own development.

Kt-K2 should have been played here in order to play BxB; 17. QxB, B-Kt5 with Kt-B4, in answer to 16. Q-Kt2. Black is still open to attack in consequence of his broken Kingβs side, but there is no demonstrable advantage for White. The text move is a mistake, and gives White chances of a decisive attack.
16. KtxKt BxKt
17. BxB PxB
18. BxP! Q-Kt4
Of course not PxB, on account of 19. QxPch, K-R1; 20. QxPch, K-Kt1; 21. R-Kt3, etc. 18. β¦ P-B4 fails because of 19. R-Kt3.
19. B-K4 P-B4
20. P-B4!!
This elegant continuation decides the game. If PxP, White simply plays 21. B-Q3, and Black can hardly hope to save the end-game, as his pawns are broken up. If the Queen retreats, however, there follows: 21. PxP, and White obtains two passed pawns for the B and has the superior position.

GAME No. 47
White: Tartakower. Black: Asztalos.
Dutch Opening.
1. P-KB4 P-Q4
It has been tried to refute Whiteβs non-developing first move by a pawn sacrifice: 1. β¦ P-K4; which leads to a rapid mobilisation of the Black forces after 2. PxP, P-Q3; 3. PxP, BxP. But this attackβcalled the From Gambitβdoes not seem to prevail against the best defence. In a match game, Tartakower-Spielmann (Vienna, 1913), White won as follows:
4. Kt-KB3, P-KKt4; 5. P-Q4, P-Kt5; 6. Kt-K5, Kt-QB3; 7. KtxKt, PxKt; 8. P-KKt3, P-KR4; 9. B-Kt2, P-R5; 10. Q-Q3, B-Q2; 11. Kt-B3, R-Kt1; 12. Castles, PxP; 13. PxP, P-QB4; 14. B-B4, BxB; 15. RxB, Q-Kt4; 16. Kt-K4, Q-R3; 17. KtxP, Kt-B3; 18. KtxB, KtxKt; 19. Q-K4ch, K-Q1; 20. RxBP, R-K1; 21. QxP, Q-K6ch; 22. K-B1, Resigns.
When Black plays P-KB4 in answer to 1. P-Q4 we have the Dutch Defence. After 1. P-Q4, P-KB4, White can also sacrifice a pawn by 2. P-K4, and thereby obtain a far more favourable position than Black does in Fromβs gambit, as he is a move to the good, having already advanced his QP, e.g. 2. P-K4, PxP; 3. Kt-QB3, Kt-KB3; 4. P-B3 or 4. B-Kt5 and then P-B3. If Black captures the KBP, White obtains a powerful attack. A drastic example is found in the following little game, played by two students in an academic tournament at Petrograd: 4. P-B3, PxP; 5. KtxP, P-K3; 6. B-KKt5, B-K2; 7. B-Q3, Castles; 8. Castles, P-QKt3; 9. Kt-K5, B-Kt2; 10. BxKt, BxB; 11. BxPch, KxB; 12. Q-R5ch, K-Kt1; 13. Kt-Kt6, R-K1; 14. Q-R8ch, K-B2; 15. Kt-K5ch, K-K2; 16. QxPch!!, BxQ; 17. R-B7ch, K-Q3; 18. Kt-Kt5ch, K-Q4; 19. P-B4ch, K-K5; 20. R-K1 mate.
Blackβs best answer is to play P-Q4 after Whiteβs 4. P-KB3 (5. B-Kt5, B-B4). If 4. B-Kt5, it is not yet possible to play P-Q4 because of the threat: BxKt, Q-R5ch, and QxQP. In that case Black must first play P-QB3, after which White again obtains a strong attack by P-KB3.
Black can avoid the attacks which follow after 1. P-Q4, P-KB4; 2. P-K4, by playing P-K3 on his first move, and then lead into the Dutch defence with P-KB4 on his second move. He must, however, reckon with having to play the French defence which White can bring about with 2. P-K4.
2. P-K3 P-K3
3. Kt-KB3 P-QB4
4. P-QKt3 Kt-QB3
5. B-Kt5 Kt-B3
Black should have played B-Q2 here, as White can exchange at B6, leaving Black with a doubled pawn. This in itself is not a drawback, but in the present position it is serious, as Black will have difficulty in finding a place for his QB. For there is no prospect of enforcing P-K4, as White commands that square in sufficient force.
6. B-Kt2 B-K2
7. Castles Castles
8. BxQKt PxB
9. Kt-K5 Q-B2
10. P-Q3 P-QR4
Blackβs attempt of capturing his K4 by playing Kt-Q2 and P-B3, White would cross at once with Q-Kt4. With the text move Black begins operations on the Q side, which is quite correct, as White has the upper hand on the other wing.
11. Q-K2
White should have prevented the further advance of the Black RP by 11. P-QR4. This would have been sound policy in any case, as the R file could not have been forced open for the Black Rooks.
11. β¦ P-R5
12. Kt-Q2 PxP
Premature. The capture is only of value if the file can be held. To that end it is first necessary to play B-Kt2 and to occupy the R file with Rooks and Queen. After the exchange of Rooks, Black is at a disadvantage for the end-game because of the inefficiency of the QB.

If instead of the text move Black had driven off the Bishop to B1 with P-R6 (13. B-B3?, P-Q5!; 14. PxP, Kt-Q4) he could have enforced his P-K4, but in the long run White would have captured the QRP, and remained with a passed pawn on the R file, a powerful weapon for the end-game, e.g. l2. β¦ P-R6; 13. B-B1, Kt-Q2; 14. KtxKt, BxKt; 15. P-K4, P-KB3; 16. P-B4, followed by Kt-Kt1.

By advancing his RP White has weakened Blackβs KB3, with the constant threat of establishing his Kt there and of capturing the RP.
25. K-B1
This move is superfluous and probably dictated by time pressure. The proper plan is: Q-QKt2 with the threat of B-B7 or Kt8 and Q-R8ch.
25. β¦ Q-R6
26. Q-QKt2
The end-game is a clear win for White. He plays his Kt to KKt4, threatening to reach B6 or K5.
