1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. d2d3  4... g8f6  5. e1g1  5... d7d6  6. c2c3  6... c5b6  7. f1e1  7... h7h6  8. a2a4  8... e8g8  9. h2h3  9... a7a5 Sometimes it seems to me that any order of moves is playable for both sides in the Italian Opening. 10. b1d2  10... c6e7 A typical maneuver: the knight aims for g6 and Black also prepares ...c6 and ...d5. 11. d3d4  11... e5d4 [%c_effect d4;square;d4;type;Inaccuracy;persistent;true] This move is connected with a wrong idea and has been played only once before. 12. c3d4  12... d6d5 [%c_effect d5;square;d5;type;Inaccuracy;persistent;true] The natural follow-up to the previous move, but perhaps 12...Nc6 is better. The computer is quick to spot the problem with the move played in the game and dismiss it as a bad one. 13. e4d5 [%c_effect d5;square;d5;type;Mistake;persistent;true] This was probably played on reflex, but advancing the pawn to e5 is much stronger. 13... e7d5 Black has a fine position now, since the isolated pawn is firmly blocked. 14. d2f1  14... c8e6  15. d1b3  15... d8d6  16. c1d2  16... f8e8  17. f1g3 Both players make natural moves, improving their pieces. 17... d5f4 Exchanging pieces is a good strategy when playing against an isolated queen's pawn. 18. c4e6  18... f4e6  19. d2c3  19... e6f4  20. e1e5  20... f4g6 This gives White some chances to gain the initiative. 21. a1e1 [%c_effect e1;square;e1;type;Mistake;persistent;true] A blunder. 21... g6e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 22. d4e5  22... d6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] This move, which would of course be impossible with the rook on d1, is what Nepomniachtchi missed. Here, Black is an exchange ahead, but the adventures are far from over. 23. b3c2  23... f6d7  24. e1e4 White launches a desperate attack with all his pieces and it doesn't seem easy for Black to defend with little time. 24... d7c5 [%c_effect c5;square;c5;type;Mistake;persistent;true] This natural move is wrong. 25. e4g4  25... a8d8 [%c_effect d8;square;d8;type;Mistake;persistent;true] Another mistake and now White can achieve a winning attack. 26. g1h2 [%c_effect h2;square;h2;type;Mistake;persistent;true] 26... c5e6  27. g3h5  27... d5d3  28. c2c1 White's attack still seems to be devastating, but now Martinez finds a magnificent move, albeit one that is absolutely forced. 28... g7g5 [%c_effect g5;square;g5;type;Brilliant;persistent;true] Everything else just loses. 29. c3d2 [%c_effect d2;square;d2;type;Inaccuracy;persistent;true] This makes things easier for Black. 29... g8f8  30. h3h4  30... e6d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] Preparing to exchange pieces and also threatening White's loosely placed bishop on d2. 31. f3g5 A man is not afraid when there's nothing to lose. 31... d4e2 The simplest. White's queen and bishop are both under attack. 32. g5h7  32... f8e7  33. d2g5  33... h6g5  34. c1g5  34... e7d7  35. h7f6  35... d7c8 The king has completed his journey to safety. The game is over. 36. f6e8
