1. Nf3 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. h4 Bg7 6. h5 Nc6 7. g3 Bg4 8. h6 Bxc3 9. dxc3 Qd6. For 9. ... Qd7 10. Bg2 f6 11. Ne5 see Ivanišević – Bok, 73rd Tata Steel Chess Tournament C-Group, Wijk aan Zee 2011. 10. Bg2 0-0-0 11. Ng5 Ne5 12. Qa4. “I saw 12. Qa4 this morning”, then said 丁立人 (Dīng Lìrén). 12. ... Nb6 13. Qd4 f6. Black’s position is already a bit uncomfortable. If 13. ... Qxd4 14. cxd4 Rxd4 then 15. b3 followed by Bc1-b2 and White stands better. 14. Bf4. 韦奕 (Wéi Yì) now thought for a long time (about 30 minutes) on how to get out of his precarious situation. 14. ... Qxd4 15. cxd4 Nc6!? A very interesting Exchange sacrifice. After 15. ... Rxd4 16. Bxe5 fxe5 17. Rc1 it’s not easy for Black to defend. 16. Nf7 Nxd4 17. Rc1 e5 18. Rh4 exf4 19. Nxd8 Much stronger would have been 19. Rxg4 Nxe2 20. Bxb7+! Kxb7 21. Nxd8+ Rxd8 22. Kxe2 with a great advantage for White.

19. ... f3! A pretty intermezzo. 20. exf3 Nxf3+ 21. Bxf3 Re8+ 22. Kd2 Bxf3 23. Nf7 Bc6. Here 23. ... Re2+ 24. Kd3 Re7 looks much better. 24. b4 a6 25. a4. A deflecting Pawn sacrifice. 25. ... Nxa4. Clearly not 25. ... Bxa4?? on account of 26. Nd6+. If, instead, 25. ... Re7 then 26. Nd6+ cxd6 27. b5. 26. Re1. Even more convincing was 26. Rf4 Nb6 27. Rxf6 Nd5 28. Rxg6 hxg6 29. h7 liquidating into a favourable ending the Exchange up for a Pawn. 26. ... Nb6 27. Rg4 Rg8 28. Re7 Nd5 29. Nd6+. Creating a very dangerous passed Pawn which may prove decisive in mutual time trouble. 29. ... cxd6 30. Rxh7 g5 31. Re4 Rg6 32. Re6 g4? As then suggested by 丁立人 (Dīng Lìrén), after 32. ... Kd8 33. Rxd6+ Ke8 Black should hold. 33. Rxd6 Nxb4? The last mistake, due to time trouble. Black should have played 33. ... Kb8 still with good chances for a draw. 34. Rh8+ Kc7 35. Rd4 Nd5 36. h7 Rh6 37. Rxg4 Ne7 38. Rg7 Kd7 39. Rf8 1 : 0.
