1. c2c4 The humble Wesley So explained in detail the problem he faces when preparing against Caruana—you can spend a whole day expecting one opening and receive a totally different move at the beginning. He also added a compliment for his opponent, saying that Caruana can outplay anyone even if he plays an opening for the first time. 1... e7e5  2. d2d3  2... g8f6  3. g1f3  3... b8c6  4. a2a3 A favorite line of Bent Larsen, who liked the Najdorf so much that he decided to play it with White as well, and with an extra tempo. The great Dane went further, adopting this approach to more openings. Nowadays this line has also been successfully implemented by rising stars Arjun Erigaisi and Vincent Keymer. 4... g7g6 A flexible reply. 5. g2g3  5... f8g7  6. f1g2  6... d7d5  7. c4d5  7... f6d5 Now this is a reversed fianchetto line against the Dragon, a very stable line for the second player, despite White's extra tempo. 8. e1g1  8... e8g8  9. c1d2  9... a7a5 Stopping b2-b4 has its merits, but there are some drawbacks too. 10. b1c3 [#] 10... d5f6 A novelty, which feels somewhat artificial. 11. a1c1  11... f8e8  12. c3b5 Highlighting the drawback of the a7-a5 advance. White can now prepare d3-d4 comfortably. 12... h7h6  13. d2e3  13... f6d5  14. e3c5 A good diagonal for the bishop $1 Things are starting to look dangerous for So. 14... c6b8 And he finds an original idea to solve the problem of the central breakthrough. 15. e2e4  15... d5f6  16. a3a4 [%c_effect a4;square;a4;type;GreatFind;persistent;true] Nagging pressure. 16... b7b6 \"My problems started with this move.\" (So) 17. c5a3  17... b8a6 It was only here that Black realized that he was heading in the wrong direction... 18. d3d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] The time is perfect for the breakthrough $1 18... c8b7  19. f3e5  19... b7e4 Hoping to stabilize somehow, but... 20. g2e4  20... f6e4  21. e5f7 [%c_effect f7;square;f7;type;Brilliant;persistent;true] A powerful blow $1 \"I just wanted to resign, because he sees everything.\" (So) 21... d8d5  22. f7e5 Caruana has won a key pawn and is completely winning. What happens from here on is fiction... 22... e4g5 The only try to muddy the waters. 23. h2h4  23... e8e5  24. d4e5  24... g5f3  25. g1h1 An only move. 25... d5b7  26. c1c3 Such an obvious move, and the first inaccuracy of the game from Caruana. 26... f3d2 As So explained, he wanted to resign on multiple occasions, but every time the thought occurred he would tell himself to survive another move, or two. 27. h1h2  27... d2f1  28. d1f1  28... b7e4  29. f2f4  29... a8d8  30. f1c4 Finally, Caruana reaches a winning endgame. 30... e4c4  31. c3c4  31... c7c5 At least So has managed to exclude the opponent's bishop from the game. For now. 32. h4h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] A powerful idea $1 The two connected passers are more valuable than the extra pawn. 32... g6h5  33. c4e4  33... g7f8  34. h2g2  34... g8f7  35. f4f5 The material is at least equal but the quality of the pawns cannot even be compared. White's only problem was that he was burning a lot of time on the clock. And, that there was no increment according to the tournament rules. 35... f8e7  36. b2b3  36... a6b4  37. a3c1 Caruana misses a win $1 37... e7g5  38. b5d6  38... f7e7  39. c1f4  39... b4c6  40. d6b5 [%c_effect b5;square;b5;type;Mistake;persistent;true] The only explanation for a move like this can be time-trouble. 40... c6d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] So grabs his chance. 41. f5f6  41... e7f7  42. b5d4  42... c5d4  43. e5e6 Now it is a draw by force. 43... f7f6  44. f4c7  44... d8e8  45. c7b6  45... d4d3  46. b6a5  46... d3d2  47. e4d4  47... e8e6  48. g2f3  48... e6e3  49. f3f2  49... e3b3  50. a5d2
