Dominguez already knew it from a blitz game played in 2016. 7... c5c4  8. d1c2  8... b7b5  9. b2b3 White tries to break up the pawn structure, but Black has resources of his own. 9... f8g7  10. c1b2  10... d5b4  11. c2c1  11... g7b2  12. c1b2  12... e8g8  13. e1g1 A new move. White quickly went downhill in the only game played before, which went 13... a8b8  14. a2a3  14... c8f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] 15. f3h4  15... f5e4  16. g2e4  16... b4d5  17. b3c4 This exchange helps Black, as the rook on b8 becomes active. It is more prudent to start with 17... b5c4  18. b2c2  18... c6a5 Nepomniachtchi's opening experiment was clearly unsuccessful. 19. a1b1  19... d5f6  20. e4g2  20... d8d6  21. h4f3  21... b8b1  22. f1b1  22... d6a3  23. f3d4  23... f8c8  24. h2h3 A somewhat mysterious move, but it gives air to the king and may be speculating on g3-g4 in future. 24... e7e5  25. d4b5  25... a3c5  26. c2a4  26... a5b3  27. a4a6 [%c_effect a6;square;a6;type;GreatFind;persistent;true] 27... c8b8 [%c_effect b8;square;b8;type;Inaccuracy;persistent;true] This move allows White to capture the c-pawn. 28. b5a3 [%c_effect a3;square;a3;type;GreatFind;persistent;true] 28... g8g7  29. a3c4  29... b8b4  30. c4e3  30... e5e4 Black starts to get into trouble after this move, which opens the a1-h8 diagonal. 31. a6a3 [%c_effect a3;square;a3;type;GreatFind;persistent;true] 31... c5b6  32. d2d3  32... e4d3  33. e2d3  33... a7a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] It's necessary to protect the rook on b4, even though this loses a pawn. 34. e3c4  34... b6b5  35. c4a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] 35... b4a4  36. a3b3  36... b5a5 Who would have imagined that after suffering so much in the opening and middlegame, White would achieve an endgame with an extra pawn $2 It should be drawn without any major problems, it's true, but I have the impression that this residual memory affected the remaining play, since they both made more mistakes than expected. 37. b3b5  37... a5a7  38. b5e5  38... a4a5  39. e5e3  39... a7c7  40. d3d4 White manages to advance the pawn. The evaluation of the game won't change for a long time. Let's fast forward to a critical moment. 40... a5a7  41. b1c1  41... c7d8  42. d4d5  42... a7d7  43. e3d4  43... g7g8  44. c1c5  44... f6e8 [%c_effect e8;square;e8;type;GreatFind;persistent;true] The knight is known as an excellent blockader. 45. c5c6  45... d8e7  46. g2f3  46... e8d6  47. g1g2  47... d7d8  48. h3h4  48... h7h5  49. c6a6  49... d6f5  50. d4a1  50... d8d6  51. a6a8  51... d6d8  52. a8a2  52... e7d6  53. f3e4  53... d8e8  54. a2a8  54... f5g7  55. a8a6  55... d6e7  56. e4d3  56... e8d8  57. a6a7 Here the drama begins again. 57... d8d7 [%c_effect d7;square;d7;type;Mistake;persistent;true] 58. a7d7  58... e7d7  59. a1a8 The important detail is that the white queen can use the c6-square as support. 59... d7e8  60. a8c6 [%c_effect c6;square;c6;type;Mistake;persistent;true] 60... g8f8  61. c6c5  61... f8g8  62. d5d6  62... e8a8  63. g2g1  63... a8a1  64. g1g2  64... a1a8  65. g2h2  65... g7e6  66. c5c4  66... a8a7 [%c_effect a7;square;a7;type;Mistake;persistent;true] 67. h2g2  67... a7d4  68. c4d4  68... e6d4  69. d6d7 [%c_effect d7;square;d7;type;Mistake;persistent;true] After this mistake, Black is able to escape. 69... d4c6  70. d3b5  70... c6d8  71. g2f3  71... g8f8  72. f3e4  72... f8e7  73. f2f4  73... d8e6 The knight performs miracles and saves Black. 74. b5c6  74... e7d6  75. c6a4  75... e6c5  76. e4d4  76... c5d7  77. a4d7  77... d6d7  78. f4f5  78... d7e7  79. d4e5  79... f7f6  80. e5f4  80... g6f5  81. f4f5  81... e7f7  82. f5f4  82... f7e6
