Tal's decisive game
If any single-game in the candidates' tournament was decisive it was surely the one given below, which enabled Tal to establish a clear lead over Keres. The game has several remarkable features, not the least being the very different verdicts about it by distinguished annotators.
Paul Keres vs Mikhail Tal
Bled-Zagreb-Belgrade Candidates (1959), Bled, Zagreb & Belgrade YUG, rd 17, Oct-06
Sicilian Defense: Kan. Modern Variation (B42) 0-1
- Better than 6. … NPxN; with which Tal got into difficulties against Smyslov two rounds earlier.
- If 8. … N-B3; 9. N-B4 N-Q2; 10. P-QR4 R-QN1; 11. P-R5, followed by B-K3, White would have a tremendous positional advantage owing to his stranglehold on the queen's wing; but after the text move Black can meet 9. N-B4 by P-QN4.
- Signalling his intention of a king's side attack, but the positional treatment with 10. P-R5 B-QB4; 11. N-B4, followed by B-K3 still seems more promising.
- White probably already has his following plan in mind, but simpler if less ambitious is 27. B-N5 R-Q1; 18. QR-Q1.
- Here the annotators begin to disagree with each other. O'Kelly (in the Belgian “Le Phare”) claims that White is left without counterplay by 19. P-B3, overlooking the reply 19. … NxP; 20. QxPch K-R1; 21. B-K3 BxB; 22. PxB R-Q3; 23. Q-N3 N-B4; 24. Q-B2 K-N2 with at least equality for Black, Pirc (in “Schach-Echo”) also condemns 18. RxR and prefers 18. B-N5, but White's actual move is probably playable, even though Keres has clearly miscalculated its consequences.
- Both sides are now playing with fire (Black could still equalise by 19. … Q-B2). The threat is 20. … QxPch; 21. QxQ BxQch; 22. KxB NxPch; so the reply is forced.
- The only defence to the threatened 22. R-Q7 B-K2; 23. RxB.
- Again threatening 23. P-B3 BxP; 24. R-Q7 but Trifunovic in the Swiss “National Zeitung” points out the preferable 22. P-N4! (intending 23. B-B1 and 24. P-N5), QxP; 23. RxB PxR; 24. P-K5, and White has the game continuation with the important improvement that his king has the square KN2 available.
- After this move all the grandmasters and seconds in the tournament hall considered Tal to be lost. Keres's second, Mikenas, was even noticed humming Wagner's death march.
- It was this fine resource which Keres overlooked and which Tal had already foreseen with 19. … Q-Q5. O'Kelly and Pirc note that if now 25. BxN Q-B8ch wins the knight. But Trifunovic goes further: 26. K-R2 QxN; 27. B-N5 Q-N2 (27. … Q-R4; 28. P-N4); 28. B-B6 Q-R3 (if 28. … Q-N1 the queen is permanently boxed in); 29. B-N5 with a draw by repetition of moves.
- Now Black is on top, for White cannot permit the exchange of queens (e.g. 26. Q-B4 Q-K8ch; 27. K-R2 Q-K4) because of the onrushing black pawns.
- An inaccuracy which jeopardises the win; much better is 36. … P-R4.
- Overlooking the resource of 37. Q-B4 (threatening both 38. Q-B8ch R-K2; 39. Q-N7 and 38. B-B4). the point is that if in reply 37. … P-Q7; 38. BxP! QxB; 39. Q-B8ch R-K1; 40. Q-B5ch and White mates. Now, however, Black wins easily.
