Grünfeld Defence D86

1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 8. Ne2 Nc6 9. Be3 0-0 10. 0-0 Qc7 11. Rc1 Rd8 12. Bf4 Be5. For the more stereotyped see 12. ... e5 13. Bg5 Rd6 see Caruana – Svidler, 17th European Team Championship, Novi Sad 2009. 13. Bxe5 Nxe5 14. Bb3 Ng4 15. Ng3 Qf4 16. Qe1! An inspired novelty, found two months earlier by Caruana and his coach Boris Avrukh – the threat is h2-h3. For 16. Qf3 Qxf3 17. gxf3 Nf6 see Cheparinov – Ivanchuk, Cap d’Agde 2008. 16. ... Nf6. 16. ... cxd4 17. cxd4 Rxd4 18. h3 Nf6 19. Ne2 is obviously bad, while 16. ... b6 17. h3 Nf6 18. e5 transposes to the game with the interpolation of the moves h2-h3 and ... b7-b6. 17. e5 Nd5 18. Bxd5! Rxd5 19. c4 Rd8. If 19. ... Rxd4? then 20. Ne2 Qxe5 21. Nxd4 Qxd4 22. Qxe7 with huge advantage for White. 20. d5. White’s Pawns centre is imposing. 20. ... b5!? 21. Qa5 Bd7 22. Rfe1! Be8. The counter 22. ... Qd4 23. e6! fxe6 fails to the zwischenzug 24. Rcd1! Qf6 25. dxe6 (Caruana’s analysis). 23. cxb5. After the impulsive 23. Qc7 Rac8! 24. Qxe7 Rd7! 25. Qf6 Qxf6 26. exf6 bxc4 Black is certainly not worse. 23. ... Rxd5 24. b6 Rd2? Caruana expected 24. ... Rxe5 with double-edged consequences; for example: 25. b7 Rb8 26. Qxa7 Rxe1+ 27. Rxe1 Bc6 28. Qxc5 Bxb7 29. Qxe7 with a small plus (Monokroussos). 25. Ne4! Rb2. On 25. ... Re2 26. b7! (not 26. Rxe2? on account of 26. ... Qxc1+ 27. Re1 axb6!) 26. ... Rb8 27. Qc7 and White wins. 26. Qxc5 Rxb6. 26. ... axb6 is refuted by 27. Qd4! threatening both Qd4xb2 and Ne4-f6+. 27. Qxe7 Bc6 28. Nf6+ Kg7 29. Rf1!! A “silent” prophylaxis before the final assault. 29. ... h6. In order to play ... Qf4-g5, as 29. ... Qg5?? at once would be refuted by 30. Ne8+. 30. Rc3 Rab8 31. Qc5. After 31. Rg3 Qf5! any White’s advantage vanishes. 31. ... Ra6. Intending ... Rb8-b5. If 31. ... Rb1 White has to settle for 32. Rcc1 with a Pawn more, as 32. Qxc6 Rxf1+ 33. Rxf1 Rb1+ 34. Ke2 Rb2+ 35. Rc2 Qc1! clears any advantage. 32. Qd6! Rbb6. Also after 32. ... Rc8 33. a3 Qg5 (or 33. ... Bb7? 34. Rxc8! Rxd6? 35. Rg8++) 34. Rg3 White wins. 33. Re3? A delay. The immediate 33. Nh5+! gxh5 34. Rg3+ Kh7 35. Qf8 would have won right away. 33. ... Rxa2? More stubborn is 33. ... Qb4, although after 34. Nh5+! Kh7 (if 34. ... gxh5? then 35. Qf6+ Kg8 36. Rg3+ Kf8 37. e6! finis) 35. Qf6 Qf8 36. e6! Ba4 (or 36. ... Bb5 37. Rfe1) 37. Nf4 White holds a powerful attack.

34. Nh5+! Never too late! A tragic qui pro quo was instead 34. Qd8?? Qxf2+! 35. Rxf2 Rb1+ 36. Rf1 Rxg2+ and mate next move. 34. ... gxh5 35. Rg3+ Qxg3 (35. ... Kh7 36. Qf8) 36. Qf6+ Kg8 37. hxg3 Be4. 37. ... Bxg2 38. Qd8+ is useless. 38. Qd8+ Kh7 39. Rc1 Bf5 40. Rc7 Be6 41. Rxa7 Rxa7. Or 41. ... Rb1+ 42. Kh2 Rxa7 43. Qd3+ and wins. 42. Qxb6 Ra4 43. Qb1+ Kg7 44. f4. Intending f4-f5-f6. 44. ... Ra5 45. Qd1! The last finesse, as after 45. f5? Rxe5! Black would still have hoped to build a fortress. 1 : 0.
