Meteoropathy


Just two lines by Miss Lonelyhearts


Baadur Jobava – Jan H. Timman
Match Game 2; Hoogeveen, October 13, 2014
Queen’s Indian Defence E12

1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. a3 Ba6 5. Qc2 Bb7 6. Nc3 c5 7. e4 cxd4 8. Nxd4 Nc6 9. Nxc6 Bxc6 10. Bf4 Nh5 11. Bd2. All over the world nearly everyone recalled 11. Be3 Bd6?? (for 11. ... Qb8 12. g3 f5 see Lutz – Karpov, Dortmund 1993) 12. Qd1 1 : 0 Christiansen – Karpov, Wijk aan Zee 1993, match game 1. 11. ... Qc7 12. g3. Departing from 12. Nd5 Qb7 13. Bd3 Bd6 14. 0-0 Qb8 15. g3 exd5 16. exd5 Bb7 17. Rfe1+ Kd8 18. Bc3 Nf6 19. b4 Qc7 20. Qb2 Kc8 21. Bxf6 gxf6 22. Qxf6 Rd8 23. Rac1 Bf8 24. c5 bxc5 25. bxc5 a5 26. c6 dxc6 27. dxc6 Ba6 28. Bf5+ Kb8 29. Qxd8+ Qxd8 30. c7+ 1 : 0 Jobava – Iturrizaga Bonelli, Khanty-Mansiysk 2009. Jobava said: “I tried to remember that game but of course I couldn’t”. 12. ... Bc5 13. Bg2 0-0 14. 0-0 Rac8 15. Rac1 Nf6 16. b4 Be7 17. Qd3 Qb8 18. h3 Rfd8. Jobava said afterwards that 18. ... d6 would have been better. 19. Rfe1 Bb7 20. e5 Ne8 21. Ne4 d6 22. exd6 Bxd6. The alternative was 22. ... Nxd6 in order to answer 23. Bf4 by 23. ... Qa8. 23. Qe2 Be5. Worth considering and possibly better was 23. ... Be7!? (Jobava). 24. c5. Sharper was 24. Ng5! Bxg2 25. Qh5 with a promising attack. 24. ... bxc5 25. bxc5 Bc6 26. Ba5 Rd7. Jobava: “Perhaps 26. ... Rd4 was better. The Rook may go to a4 and on 27. Bc3 you can go 27. ... Rd7 28. Bxe5 Qxe5. Ah, no, White wins material with 29. Nd6!”. 27. Ng5 Bxg2 28. Kxg2 Bf6 29. c6!? “I wanted to try something”, Jobava said. On 29. Ne4 Qa8 leads nowhere. 29. ... Rd5?? Oblivious to the danger! Grandmaster Kevin Spraggett comments: “Here Black should play 29. ... Rd6! with a perfectly reasonable game. White will lose his c-Pawn but remain with enough ‘tricks’ to keep the game roughly balanced”.


30. Nxf7!! Rxa5 31. Qxe6 Kf8 32. Rcd1? White could have won on the run with 32. Qd7! Rxa3 (or 32. ... Rc7 33. Rxe8+ Qxe8 34. Qxc7 Rxa3 35. Nd6+-) 33. Rb1 Qa8 34. Rb7+-, as originally shown by Grandmaster Kevin Spraggett. 32. ... Qc7? “32. ... Qa8! is unclear”, Spraggett says. We give a sample variation: 32. ... Qa8! 33. Nd6! Nxd6 34. Qxd6+ Kg8 35. Re6 Rd8 36. Rxf6! Rxd6 37. Rfxd6 and most probably White will survive. 33. Nd8! Rxd8 34. Rd7! 1 : 0. “Incredibly stupid”, Timman moaned.

Anatoly Yevgenyevich Karpov – Lajos Portisch
Linares, 1989
Queen’s Gambit Declined D31

Notes by Grandmaster Jan Timman, New In Chess, 2008/2, p. 35.

1. d4 d5 2. c4 e6 3. Nc3 Be7 4. cxd5 exd5 5. Bf4 c6 6. e3 Bf5 7. g4 Bg6 8. h4 h5 9. g5 Bd6 10. Nge2 Na6 11. Bxd6 Qxd6 12. Nf4 Nc7 13. Be2 Qb4 14. Qd2 Ne7 15. Bf3 Ne6 16. Nce2 Nxf4 17. Nxf4 Qxd2+ 18. Kxd2 Be4 19. Bxe4 dxe4 20. Rac1 0-0-0 21. Rc5 Nd5 22. Nxd5 Rxd5 23. Rhc1 Rhd8 24. b4 Kc7 25. Ke2 a6 26. f3 exf3+ 27. Kxf3 R5d6 28. Rf5 R8d7 29. Rcc5 Re7 30. Rce5 Kd8 31. a4 g6 32. Rxe7 Kxe7 33. Re5+ Kf8 34. Ke4 f6 35. gxf6 Rxf6 36. b5 axb5 37. axb5 Kf7 38. Rc5 Ke7 39. Rg5 Kf7 40. Rg2 Rf5 41. bxc6 bxc6 42. Rc2 Rf6 43. Ra2 Ke7 44. Ra7+ Kd6 45. Rg7 Ke6 46. Kd3


Here Portisch played 46. ... Kd6? and after 47. e4 he was hopelessy lost.
[Robert James] Fischer indicated that he could have drawn with 46. ... c5!. It is essential to tear down the white pawn structure. It is clear that 47. dxc5 Kd5 won’t yield White anything. The crucial move is 47. Ke4, after which a pawn ending arises by force that is just within drawing territory. Fischer’s main variation went as follows: 46. ... c5 47. Ke4 cxd4 48. exd4 Kd6 49. d5 Kc5 50. Rc7+ Kd6 51. Rc6+ Ke7 52. Rxf6 Kxf6 53. Kf4 Kf7! 54. Ke5 (or 54. Kg5 Kg7 55. d6 Kf7) 54. ... Ke7 55. d6+ Kd7 56. Kd5 g5!, and the black h-pawn will queen with check. An impressive feat of analysis.
47. ... Rf4 48. e5+ Ke6 49. Rxg6+ Kd7 50. Kc4 Rf1 51. Rh6 Rc1+ 52. Kd3 c5 53. d5 c4+ 54. Kd2 Rh1 55. Rh7+ Ke8 56. Rxh5 Rh3 57. Kc2 1 : 0.
