1. e2e4 1.e4 is usually a good move, even if the position is not what we're used to. 1... e7e5  2. f2f3 A bit timid. 2... f7f5  3. h1g3  3... f5f4  4. g3e2 Black managed to gain space and should be fine, but I never know what to expect in the first moves of these random positions. That's exactly why I'm such a big fan of this form of chess. 4... c7c6  5. d2d4  5... g7g5 This is slow. It would have been better to develop the knight immediately. 6. a2a4 White's pieces are somewhat cramped, and it's difficult to prepare castling. This is a nice way to gain space and give some life to the a-rook. 6... h8g6  7. a4a5  7... g8c4  8. b1a2  8... c4a6  9. d4d5  9... d7d6 This a clear mistake. The dark-squared bishop will remain shut from the game. 10. c2c4  10... b8c7  11. b2b4 White already has a nearly decisive advantage. The a6-bishop is in trouble. White will prepare b4-b5 soon, so Black has to weaken the position. 11... b7b5  12. a5b6  12... a7b6  13. a2b3  13... c6c5  14. e2c3  14... c8b8  15. f1f2  15... a6b7  16. a1a8  16... b7a8  17. c3b5  17... f8f6  18. f2a2 We can say that the position is more or less normal now, that is, there's nothing so strange as the initial position in the game. White has an overwhelming advantage. 18... a8b7  19. b5a7 The plan is b5 followed by Nc6. 19... g6e7  20. b4b5  20... f6g6  21. a7c6 If the knight is captured, then White gains a powerful passed pawn, and the b5-square becomes available for the other knight. But how is it possible to survive playing against such a monster piece $2 21... b8c8  22. g2g3 Keeping some options on the kingside as well. At this point, Caruana was probably considering using the h3-c8 diagonal either for the queen or for the bishop. 22... c8d7  23. d1f2  23... e8f8  24. b3d1  24... b7c8  25. f2d3  25... e7c6 Nakamura finally decides to exchange knights, but this makes things worse. 26. b5c6  26... d7e8  27. g3g4 Caruana judges that he has enough to win on the queenside, so he closes the other flank. 27... d8f7  28. a2a8  28... e8e7  29. d3b2 The knight starts the journey to the b5-square. Black is deprived of any counterplay. 29... f8d8  30. b2a4  30... h7h5  31. a4c3  31... b6b5 Giving up a pawn so that the bishop at least gains the b6-square. 32. c3b5  32... c7b6  33. h2h4  33... h5g4  34. f3g4
