Bortnik is an expert in this line, also played recently by Carlsen in an important game. 7. d4d5 This is the machine's favorite move. The plan is simple: to play Nc3 followed by e4. 7... b6b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] 8. d1b3 [%c_effect b3;square;b3;type;GreatFind;persistent;true] Exploiting the pin. 8... a7a6  9. b1c3  9... c7c6  10. f1d1 A new move. 10... c6d5  11. c4d5  11... d7d6  12. a2a4  12... b8d7  13. c1e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] The most accurate move. 13... d7c5 After this move, the game goes to an endgame by force where White has an extra pawn, and Black fights for a draw. 14. e3c5  14... d6c5  15. a4b5  15... a6b5  16. b3b5  16... a8a1  17. d1a1  17... b7d5  18. a1d1  18... d8a8  19. b5c5  19... d5f3 [%c_effect f3;square;f3;type;Mistake;persistent;true] 20. g2f3  20... a8b8  21. d1d2 [%c_effect d2;square;d2;type;Mistake;persistent;true] 21... e7e6  22. g1g2  22... h7h5  23. h2h4  23... f8c8  24. c5b5  24... b8b5  25. c3b5  25... c8b8  26. b5d4 Another endgame that should be drawn with perfect play. But perfection is impossible, even more so in a rapid game. 26... b8b6  27. d4c6  27... g7f8  28. e2e3  28... g8g7  29. c6e5  29... b6b5  30. e5c4  30... f8e7  31. d2c2  31... f6d5  32. f3d5  32... e6d5  33. c4e5  33... e7f6 [%c_effect f6;square;f6;type;Mistake;persistent;true] After this, the defensive task is really difficult. 34. e5d3  34... b5b3  35. c2d2  35... d5d4 [%c_effect d4;square;d4;type;Inaccuracy;persistent;true] 36. e3e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] Now the position is winning. The king will go to e2, the rook is free to become active, and then White can start advancing the kingside pawns. 36... f6d8  37. e4e5  37... d8a5  38. d2d1  38... a5c7  39. g2f1 [%c_effect f1;square;f1;type;GreatFind;persistent;true] 39... f7f6  40. e5f6  40... g7f6  41. f1e2  41... c7d6  42. d1c1  42... f6e6  43. c1c8  43... b3b6  44. c8g8  44... e6f7  45. g8a8  45... f7e6  46. e2f3  46... e6d5  47. a8a5  47... d5c4  48. f3e4 The d-pawn is doomed. 48... d6b4  49. a5d5  49... b6e6  50. d3e5  50... c4b3  51. d5d4  51... b4e1  52. f2f4  52... b3b2  53. e4f3  53... b2b3  54. d4d7  54... e1c3  55. d7g7  55... c3e5  56. f4e5  56... e6e5  57. g7g6 The rest is easy: Black's king is too far away, and the h5-pawn will soon fall. 57... b3c4  58. g6g5  58... c4d4  59. f3f4  59... e5e4  60. f4f5  60... e4e3  61. f5g6  61... d4e4  62. g6h5  62... e4f3  63. g3g4  63... e3e8  64. g5g7  64... f3g3  65. g7h7  65... e8e4  66. h7a7  66... e4e8  67. g4g5  67... e8h8  68. h5g6  68... g3h4  69. a7a4  69... h4g3  70. g6g7  70... h8b8  71. g5g6  71... b8b7
