Chess: The Final Candidates' Match by Richard Shorman
White: Tigran Petrosian. Black: Robert Fischer. Buenos Aires, October 5, 1971, 2nd Match Game. Gruenfeld Defense. (Annotations by grandmaster Ratmir Kholmov, translated from “64,” No. 41, Oct. 8-14, 1971. pg. 16)
3. Nc3 d5(a) — Fischer employs this opening less frequently than the King's Indian Defense.
4. Bf4(b) Bg7 — White chooses a line that generally promotes a fierce struggle. Following his demise in the first game, the former world champion may have wanted to avoid calm seas.
5. e3 c5(c) — Castling first, and then 6. … P-B4, is more commonly played. Perhaps Fischer feared a prepared variation after 5. … 0-0 6. PxP, NxP 7. NxN QxN 8. BxP.
7. Rc1 Ne4(d) — Black's attack only looks dangerous, which Petrosian convincingly demonstrates.
8. cxd5(e) Nxc3 — Grandmaster Vlastimil Hort, an authority on the Gruenfeld Defense, has achieved good results using this system as Black. At Palma de Mallorca, 1970, for example, he defended this same position against Reshevsky. But Reshevsky played 8. N-B3, and after 8. … NxN 9. PxN BxPch 10. N-Q2 B-K3 obtained a good game. Petrosian's last move radically strengthens the variation for White.
9. Qd2 Qxa2(f) — On 9. … O-O or 9. … QxBP the response is 10. N-K2, e.g.; 9. … O-O 10. N-K2 NxN 11. QxQ NxR 12. Q-Q2 NxP 13. B-B4 and White must win. However, neither does the text move offer relief.
10. bxc3 Qa5(g) — It is not so easy to recover the pawn after 10. … QxQch 11. KxQ. Fischer could well have been relying on his skill in the middlegame.
11. Bc4 Nd7(h) — The American grandmaster's maneuver does not quite succeed due to Black's lack of development. He shook capture on QB4 with the queen, although even then Black remains cramped: 12. B-R2 with N-K2 to follow.
14. Bxe5(i) Bxe5 — Obviously Fischer did not expect this to happen!
15. Nd4 Qxc5(j) — He has to take the pawn. Retreating the bishop is answered by 16. P-B5.
17. O-O(k) Qa5 — At the crossroads, Black discovers that castling on either side fails against 18. Q-B2. White's opening variation has scored complete triumph.
19. c4 fxe3(l) — Somewhat better is 19. … P-N3, trying to slow down the advancing white pawns.
20. c5 Qd2(m) — On 20. … B-Q5 White obtains a strong attack with 21. P-Q6.
22. Rcd1 Qe2(n) — If 22. … PxPch 23. RxP BxPch 24. K-B1 Q-R3, then 24. P-Q6! wins.
23. d6(o) … Petrosian ignores Black's threats, while vigorously pressing the attack.
23. … Qh5(p) — If 23. … PxQP, then, of course 24. PxKP! After 23. … PxPch 24. RxP BxPch 25. KxB QxR/7 26. PxPch KxP 27. R-Q7ch K-B1 28 Q-QB4! Black must resign. In case of 26. … K-N2, in this one, Whites till wins with 27. Q-N4ch K-B3 28. R-Q6ch K-K4 29. R-Q5ch K-B3 30. Q-N5ch.
24. f4 e2(q) — Black puts up more resistance by 24. … B-B3
28. Qb3 Kg7(r) — Playing to Kt also loses: 28. … K-K1 29. QxP R-Q1 30. P-B6! Q-K6ch 31. K-R1 Q-K7 32. R-KN1. No better is 28. … P-K3 because of 29. QxNP R-K1 30. P-B6!
30. dxe7 f5(s) — After 30. … KR-KN1 (or 30. … QR-KN1) 31. RxPch R-N3 32. Q-B8ch! K-N4 White must shun 33. P-R4ch? KxP 34. RxR QxPch 35. Q-B2ch QxQch 36. KxQ PxR 37. B-B7, when matters are not so clear, capping off instead with 33. R-B2!
