1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Be3 c5 8. Qd2 0-0 9. Nf3 cxd4 10. cxd4 Bg4 11. Be2 Nc6 12. Rd1 Bxf3 13. Bxf3 e5 14. d5 Nd4 15. Bxd4 exd4 16. 0-0 Qd6. If, nonchalantly, 16. ... Rc8 then 17. g3 Rc3 18. Bg2 Qc7 19. f4 Rc2 (this is only making things worse) 20. Qd3 Rc3 21. Qb1 b6 22. e5 and White’s position looks imposing, Shipov – Ilinčić, IKO Chess Tournament, Belgrade 1992. 17. 17. Rfe1. Improvisation? For 17. g3 f5 see Hareux – Vareille, French Chess Championship Accession Tournament, Vichy 2000. 17. ... Rac8 18. Bg4 Rc4 19. f4 Qc5 20. Rc1. Consideration deserves 20. Kh1 Rc2 21. Rc1 Rxd2 22. Rxc5 Rxa2 23. d6 with a very unclear position.


20. ... f5. Here 20. ... d3+ 21. Kh1 b5 could have been more promising. 21. Rxc4 Qxc4 22. Rc1 Qb5 23. Bf3 fxe4 24. Bxe4 Qd7 25. g3 Re8 26. Qd3 Qe7 27. Re1 Qb4 28. Re2 Rc8 29. Kg2 Rc3 30. Qd2 Qd6 31. Qd1 b5 32. Bf3. Much wiser was 32. Rd2 Re3 33. Re2 Rc3 repeating the position and earning a draw. 32. ... Qc5. The Exchange sacrifice by 32. ... Rxf3! 33. Kxf3 Qxd5+ appears very promising (even if it should not win), and in any case, Zhansaya Daniyarqyzy would have risked anything. 33. Qe1 Re3 34. Rxe3 dxe3 35. Qd1 Qd4. Black decides to force a drawish ending with Bishops of opposite colour. 36. Qxd4 Bxd4 37. Be2 b4 38. Kf3 a5 39. Ke4 Bb6 40. d6 a4 41. d7 Kf8 42. d8=Q+ Bxd8 43. Kxe3 b3 44. Bc4 Bb6+ 45. Kd2 bxa2 46.
