1. d4 d5 2. c4 dxc4 3. e3 Nf6 4. Bxc4 e6 5. Nf3 c5 6. 0-0 a6 7. Nbd2 Nbd7 8. e4 cxd4?! That doesn’t give a good impression. A better course seems to be 8. ... b5 9. e5 bxc4 10. exf6 Nxf6 11. Nxc4 Bd7 12. Re1 Bb5 13. Nce5 Be7 14. a4 Bd7 15. Bg5 Rc8 16. Rc1 c4 17. Rxc4 Rxc4 18. Nxc4 Bc6 19. Nfe5 Ba8 20. a5 0-0 21. Nb6 Bb7 22. Qa4 Nd5 23. Bxe7 Qxe7 24. Qd7 Qb4 25. Nd3 Nxb6 26.

No doubt Black has come out of the opening very badly. 18. ... Kh8 19. Be3 Nd5 20. Rac1 Qd6 21. Bd2 Re8


22. Nf5! Qd8 23. Qd3 Bd7 24. Qg3 (24. Nxg7+−) 24. ... Rg8 25. Bxd5 exd5


26. Nxg7? Very exaggerated. 26. Ne7+− would have closed matters without particular difficulties. 26. ... d4! 27. Qd3 Rxg7 28. Bf4 Qf6 29. Bg3 Bf5 30. Qf3 Rag8? 30. ... Ng5 31. Qf4 d3 seems very strong. 31. Rc5! Nh6? (⌓ 31. ... Rg5) 32. Be5+− Qf8 33. Bxd4 (33. Rc7⊙+−) 33. ... Bd7. White now concludes elegantly: 34. Qxf8 Rxf8 35. Rg5 Nf5 36. Bxg7+ Nxg7 37. Re7 Ne6 38. Rh5 Bc8 39. Rexh7+ Kg8 40. Rh8+ Kg7 41. Rxf8 Nxf8 42. Rc5 Be6 43. b3 Kf6 44. f3 Nd7 45. Rc7 b6 46. Kf2 Nc5 47. Rc6 Nd7 48. g4 Ke5 49. Kg3 Bd5 50. f4+ Ke4 51. Rd6 1 : 0.
