26.... P—B 5 is answered simply by 27. R x R P, and Black's passed pawn is blockaded by Kt—B 3.
If 27. ... Q—B 2; 28. Kt—Kt 3, Q—B 3, White can increase the pressure on his opponent's loose pawns by 29. Kt—B 5 (the threat is R x R P). It would be difficult to maintain that Black could in this position support all his weak pawns —Q R, Q and K R pawns. For example: 29. ... B—B 6; 30. Kt x K R P, P—Q 5; 31. Kt—B 5! (31. ... Kt x Kt; 32. R—Kt 8 ch, winning the Queen). If 29. ... Q— B 2, then 30. Q—K Kt 4 with the idea of playing Kt—Q 7, after which White's attack becomes even more tangible. Against a passive reply P—Q R 4 would be possible.
Otherwise the Q R P is lost; but now the important K R P dies, and with its death Black's troubles, connected with the defence of his King position, increase.
- 29. QxKRP R—B5 86
This useful move not only parries the attack on the Queen but also ensures a flight square at Kt 2 for the King in case the Black Rook invades the back rank.
If 30.... R—R 5, it is sufficient to play 31. Kt—Kt 5 with mating threats; 30. ... B—B 3 could be answered in the same way.
Neither does 32.... Kt—B 3 save the game. The simplest reply is
33. Kt x Kt, R X Kt; 34. R—R 5, Q—Q 2; 35. Q—Kt 5, and White wins yet another pawn.
34. K—Kt 2, Q—K 5 on account of 35. R—Kt 8 ch, winning a piece.
Now the game is easily won. The remaining moves were:
The sealed move. White had in mind the following variation if 41. ... R x P: 42. R—Q 8 ch, Kt—B 1 (42. ... K—R 2; 43. Q— R5 mate); 43. Q x Pch! K x Q; 44. Kt—K5ch.
Black resigned without resuming.
No. 33. Ruy Lopez V. SMYSLOV M. EUWE (World Championship Tournament, 1948)
It is not without interest to recall that in the first encounter between these two players—at Groningen, 1946—Smyslov played 5. P—Q 3, which does not allow 5____Kt x P.
This time the opening follows the lines of the Open Defence, a favourite with grandmaster Euwe.
This continuation received a thorough testing in the games of the tournament. One of the peculiarities of such a competition, where the struggle takes on the character of a match, is the relatively frequent repetition of definite opening systems. In this game both sides aim for the same position, appraising it differently however.
Black removes the white-squared
Bishop so that on his next move he may take his Queen away from its dangerous position opposite the White Rook on the Q-file. However, there is no need to hurry with the exchange. Serious attention should be given to 10. ... B—K 2; 11. P— B 4, P—Q 5!, which leads to a sharp and complicated game.
Up to here the play has followed the game Keres-Reshevsky from the previous round of the tournament; White then continued 12. B—Kt 5, P—R 3; 13. B—R 4 and got into a difficult position. No doubt Euwe, as Black, was not averse to repeating this variation, but now an unpleasant surprise awaits him.
An unexpected reply, which bursts Black's position in the centre asunder. While offering a pawn sacrifice White gets excellent attacking chances against the enemy King.
The idea of the previous pawn sacrifice consists in this centralization of the White Queen. Now Black's weak points on the Q-side and his poor development begin to have their say.
With other replies White also preserved a strong attack, which more than compensates for the pawn. For example.
(1) 14. ... Q—K 3; 15. R—Q 6, B x R; 16. Q x Kt ch, K—K 2;
17. P x B ch, Q x P; 18. Q—K 4 ch, Q—K 3; 19. Q—R 4 ch, P—B 3; 20. Q—Kt 3, attacking both the Q B P and K Kt P at once.
(2) 14.... Q—Kt 2; 15. Kt—B 3, R—Q Kt 1 (or 15. ... B—B 4; 16. P—K 6, B X P; 17. Kt—K 5); 16. P—K6!
(a) 16. ... B x P; 17. Kt—Kt 5, Kt—Q 1; 18. R x Kt ch, K x R; 19. Kt X B ch, P x Kt; 20. Q x K P, B—K 2; 21. B—Kt 5!, with the threat of 22. R—Q 1 ch; or (£>) 16. ... P x P; 17. Kt—Kt 5, Kt—Q 1; 18. R x Kt ch, K x R; 19. Kt—B 7 ch, K—Kl; 20. Kt x R, with a material advantage.
(3) 14. ... Kt—Kt 5!; 15. B—Kt 5. Now what has been recommended by several analysts—15. ... B—B 4—is bad because of 16. Kt—R 3!, O—O; 17. Kt x B, P X Kt; 18. Q x P, and the Black Bishop has no retreat; or 16. ... B—Kt 6; 17. K R—Q B 1, B—B 1;
18. Kt x P, and Black's position is smashed.
Therefore in variation 3 the correct answer to 15. B—Kt 5 is 15. ... P—Q B 3, resigning oneself to the loss of the Queen after
These variations give a clear impression of the dangers involved in the defence of Black's position.
