China – Russia Match; 宁波市 (Níngbō), July 17, 2015
Queen’s Gambit Declined D11

1. d4 Nf6 2. c4 g6 3. g3 c6 4. Nf3 d5 5. Qb3 a5 6. cxd5. Another try – among others – is 6. Qa4 Nbd7 7. cxd5 Nb6 8. Qd1 Nbxd5 9. Bg2 Bg7 10. 0-0 0-0 11. Nbd2 c5 as in the game Rustemov – Gritsak, Świdnica 1999. 6. ... a4 7. Qd1 cxd5 8. Bg2 Bg7 9. 0-0 Ne4 10. Nc3 Nc6 11. e3 0-0 12. Nd2 Nxc3 13. bxc3 Qa5 14. Rb1

14. ... Bf5! A temporary, yet pretty Pawn sacrifice. 15. Rxb7 Bd3 16. Re1 Rab8 17. Rxb8. If 17. Rd7 might follow 17. ... Rfd8 with consequences similar to those in the game. 17. ... Rxb8 18. Ba3 Qxc3 19. Qc1 Qa5 20. Rd1?! “‘The Chinese Carlsen’ had prepared excellently and only Black can stand better [...]. So it was more sensible to play to hold – 20. Qxc6 Qxd2 21. Ra1 – and then calculate a couple of variations leading to equality, e.g. 21. ... Bf8! 22. Qxa4! Bb1!? 23. Qc6 Qd1+ 24. Bf1 Qf3 25. Bg2 Qd1+ 26. Bf1=”, Grandmaster Andrey Deviatkin said. 20. ... Rc8 21. Qc5?! Deviatkin recommends 21. Qb2. 21. ... e6! 22. Qxa5 Nxa5 23. Bf1? This hasty move looks quite dubious. We would have preferred 23. Rc1! as after 23. ... Rxc1+ 24. Bxc1 Bf8 25. Bf1 Bc2 26. Bb5 g5 27. f3 f5 the resulting position seems only slightly better for Black. 23. ... Bxf1 24. Kxf1 Bf8! 25. Bxf8. Now it’s too late for 25. Rc1?? because of 25. ... Nc4! and Black wins (26. Nxc4 Bxa3). 25. ... Kxf8. Black is on top, as his Rook dominates the c-file. 26. Rb1? It just makes things easier for Black, but also after 26. Nf3 Rc3 followed by ... Na5-c4 White stands very badly. 26. ... Rc2 27. Rb5 Rxd2 28. Rxa5 Rxa2. “There are too many Pawns on for the Rook ending to be held in the classical manner. With an instructive plan (Black pushed the Pawn to a2, then played ... f7-f6 and ... e6-e5, then brought the King to the d4-Pawn) Wéi Yì soon won”, Deviatkin said. 29. g4 g5 30. Ra7 a3 31. Kg2 Ra1 32. Kg3 a2 33. Kg2 f6 34. h3 e5 35. Kf3 Ke8 36. Kg2 Kd8 37. Kf3 Kc8 38. Ke2 Kb8 39. Ra3 Kb7 40. Kf3 Kc6 0 : 1. “Vitiugov didn’t quite manage Svidler’s trick of outplaying Wéi Yì in the ending!”, the guys of chess24.com said.
