大西洋鯡


Brief notes by Horace Horsecollar


李超 (Lǐ Chāo) – Fabiano Caruana
20th Sigeman & Co International Tournament; Malmö, May 14, 2012
Grünfeld D85

1. d4 Nf6 2. Nf3 g6 3. c4 Bg7 4. Nc3 d5 5. cxd5 Nxd5 6. e4 Nxc3 7. bxc3 c5 8. Rb1 0-0 9. Be2 Nc6 10. d5 Ne5 11. Nxe5 Bxe5 12. Qd2 e6 13. f4 Bc7 14. 0-0 exd5 15. exd5 Ba5 16. d6 Rb8 17. Rb5. If 17. g4 then 17. ... Bd7 18. f5 gxf5! 19. Bd3 Kh8∞ (Finkel’s analysis). And for 17. Ba3 Bf5 18. Rbd1 Rc8 see HIARCS – Junior, World Computer Chess Championship, Tilburg 2011. Bd7. The alternative is 17. ... b6 18. Ba3 Ba6 19. f5 Bxb5 20. Bxb5 Qf6 21. fxg6 Bxc3 22. gxh7+ Kh8 23. Rxf6 Bxd2 24. Bb2 Be3+ 25. Kf1 Kxh7 26. d7 Rbd8 27. Rf5 Bd4 28. Bxd4 cxd4 29. Re5 Kg7 30. Ke2 f5 31. Re8 d3+ 32. Kd2 a6 33. Bc6 b5 34. h4 Kf6 35. a3 Rh8 36. h5 Kg5 37. Re6 Rh7 38. Rd6 Rxh5 39. Kxd3 Rh4 40. Re6 Rh7 41. Rd6 Rh4 42. Re6 Rh7 43. Rd6 ½ : ½ Aronian – Vachier-Lagrave, Bilbao 2013. 18. f5! 李超 (Lǐ Chāo) goes in for sharp play. White will have fine attacking chances on the Kingside for the sacrificed Exchange. 18. ... Bxb5 19. Bxb5 Qh4 20. Rf4 Qg5 21. Qe1 Qd8. The zwischenzug 21. ... a6 was probably more to the point. 22. Qe5! Re8 23. Qd5. White could also regain the Exchange with 23. Bxe8 Qxe8 24. Qd5 preserving a small plus, but 李超 (Lǐ Chāo) likes to attack! 23. ... Re1+ 24. Kf2 g5. Forced. On 24. ... Rxc1 25. fxg6 is ruinous. 25. f6! h6. Clearly not 25. ... gxf4?? on account of 26. Qg5+ and mate next move. 26. Qf5! Qxd6. The silly 26. ... Rxc1?? 27. Bd3 loses outright. And also after 26. ... Rd1 27. Rg4! Kh8 28. Bxg5 Bxc3 29. Bxh6 Qxf6 30. Bg7+ White must win. 27. Kxe1 Rd8. 27. ... Bxc3+ 28. Ke2 is no better.


28. Kf2. “If the Chinese player have played 28. Be2!, the rating favourite probably wouldn’t come off clear”, rightly wrote the guys of Chess-News.ru. Indeed, after 28. Be2! Bxc3+ (28. ... gxf4?? 29. Qg4+ Kf8 30. Qg7+ Ke8 31. Bb5+ is suicidal) 29. Kf1 Qd5 30. Rf3 Black is getting a hard day’s night. 28. ... Qd1! The saving clause! 29. Bc4 Kh8. The Rook is still taboo: 29. ... gxf4?? 30. Qg6+ and mate next move. 30. Rf3 Qxc1 31. Bd3 Qd2+ 32. Kf1 Qd1+ 33. Kf2 Qd2+ 34. Kf1 Qd1+ ½ : ½.
