11. Qf3 Nd4. Maybe best — anachronistically speaking — is 11. ... Bb7 12. h4 Nd4 13. Qh3 Bh6 14. d3 Bxc1 15. Rxc1 e4 16. Ne2? (16. Kf1) 16. ... exd3 17. Nxd4? d2+!−+ 18. Kxd2 Qxd4+ 19. Ke1 Re8+ 20.

19. 0-0! Who knows, perhaps Black was hoping for a tactical vortex in case of 19. dxe4 Nxe4 20. Bd5 (20. Bc2 Nxf2!! 21. Kxf2 Bc5+ 22. Ke1 Re8 23. Bd3 Bb7! also gives Black excellent compensation) 20. ... Nxf2!! 21. Kxf2 Bc5+ 22. Kf1 Re8 23. Bf3 Rxe2!! (Black will be two Rooks and a Bishop down, but White can’t make any use of it!) 24. Bxe2 f3! 25. Bxa6 fxg2++ 26. Ke2 Qf2+ 27. Kd3 Qf5+ 28. Kd2 Qf2+ drawing by perpetual check. 19. ... Bxd3 20. Bc2 Ba6 21. a4! Bb7 22. a5 Nxa5 23. Ba4 Bxa8 24. b4 Nc6 25. Bxc6 Bxc6 26. Nd4 Bd5 27. Qg4 Nc8 28. Rd1 Rh6 29. Bb2. Despite the dynamic material balance, White is clearly dominating the board. 29. ... Bc4 30. b5 Rh7 31. Nc6+ Kc7 32. Nxa7 Nd6 33. Ba3 Rf7 34. Bxd6+ Bxd6


35. Nc6!! Bxb5. If 35. ... dxc6 then 36. Ra7+ Kb8 (36. ... Kd8 37. Ra8+ Ke7 38. Qc8+−) 37. Ra8+! Kxa8 38. Qc8+ Bb8 39. Ra1+ Ra7 40. Rxa7+ Kxa7 41. Qa6 mate. 36. Nd4 Bd3 37. Ra7+ Kd8 38.

Black has nothing better than return one of its two extra Pawns in order to avoid the worst, though, even thus, it has almost zero chances to hold its own in the endgame an Exchange down. 47. Qxf3 Qxf3 48. gxf3 Bb5 49. Rb8 Rf7 50. Re1+ Kd6 51. Rxb6+ Bc6 52. Kg2 Rf4 53. Re4 Rf5 54. Re3 Rd5 55. Rb4 Ra5 56. Rb2 Rd5 57. Rd2 Rf5 58. Rdd3 Rf4 59. Kf2 Bd5 60. Rd1 Be6 61. Re4 Rf5 62. Rde1 Bd5 63.
