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
