1. e4 c5 2. Nf3 Nc6 3. Bb5 Nf6 4. Bxc6 dxc6 5. d3 g6 6. h3 Bg7 7. Nc3 0-0 8. Be3 b6 9. Qd2 e5 10. Bh6. After 10. Nxe5 Nxe4 Black equalizes; for example: 11. Nxf7 Nxd2 12. Nxd8 Nf3+! etc. 10. ... Qe7 11. 0-0. For the other castling 11. 0-0-0 see Ivanchuk – Anand, PCA/Intel Rapid Chess Grand Prix 1994, third stage, London 1994. 11. ... Ne8 12. a3. Apparently, also the alternative 12. Nh2 Nc7 13. Bxg7 Kxg7 14. f4 exf4 15. Rxf4 Ne6 16. Rf2 Nd4 17. Nf3 h6 18. Re1 gives White a small plus, A. Tóth – Al Atarji, 18th Belgrade Trophy, Obrenovac 2005. But, in all likelihood, Black’s play may be improved. 12. ... Nc7 13. Bxg7 Kxg7 14. Ne2 f6 15. Nh2 Ne6 16. f4 exf4 17. Nxf4 Nxf4 18. Rxf4 Be6 19. Raf1 Rad8 20. Qc3 Bc8. Penguincw says: “I have to say, 20. ... Bc8 is probably where Black just went downhill. 20. ... c4 might be a little better (if 21. dxc4 then 21. ... Qc5+ wins it back)”. 21. R1f2 Qd6? A self-destructive oversight.

22. Rxf6! Rxf6 23. e5. Sic et simpliciter. The remainder is self explanatory. 23. ... Rxf2 24. exd6+ Rf6 25. Qe5 Rxd6 26. Qe7+ Kg8 27. Qxa7 c4 28. Qb8 cxd3 29. cxd3 Rd8 30. Nf3 h6 31. Qc7 Rdf8 32. Ne5 c5 33. Nc6 Bf5 34. Qxb6 Kh8 35. Qb7 Bxd3 36. Ne5 c4 37. Qd5 Rf1+ 38. Kh2 R1f2 39. Nxd3 cxd3 40. Qxd3 Kh7 41. b4 Ra2 42. b5 Rff2 43. Qd7+ Kh8 44. Qd5 Rfd2 45. Qc6 Kh7 46. b6 Rac2 47. Qb7+ Kh8 48. a4 Ra2 49. a5 1 : 0.
