1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... d7d5  4. b1c3  4... d5c4  5. e2e4  5... b7b5 A very fresh line which was tried on a couple of occasions by Caruana. Apparently Nakamura liked  the idea and decided to give it a try. 6. e4e5  6... f6d5  7. c3b5  7... d5b6  8. a2a3  8... b8c6  9. c1e3  9... c6a5 Played after some hesitation. The knight is  protecting the c4-pawn and is ready to jump on b3 at the right moment. 10. d1c2 The opening is over and Nakamura has a few weaknesses to worry  about. But the c4-pawn is also a strength that cramps the white bishop and secures an excellent outpost for the knight. 10... a7a6 Not only chases  the knight back home, but deprives the queen of the c3-square. 11. b5c3  11... f8e7  12. a1d1 Carlsen delays the development of his kingside. 12... c8b7  13. f1e2  13... d8d7  14. h2h4 The point! The rook is entering the  battle the French way. 14... b7c6 Logically, Nakamura is looking for a queenside play. 15. h1h3  15... a8b8  16. h3g3  16... c6a4 The only drawback of the plan- Black needs to  surrender the bishop pair. 17. c3a4  17... d7a4  18. d1c1 Another clever idea by  the world champion. 18... a5b3  19. g3g7 The black king remained in the center too long  and White wants this to continue indefinitely. 19... b3c1  20. c2c1  20... c4c3 Black needs air for his major pieces too! 21. c1c3  21... b6d5  22. c3c1  22... d5e3 An important attacker is removed. 23. f2e3  23... e8f8  24. g7g4  24... a4b3  25. c1c7  25... b3b2  26. e1f2 An obivious move, which however, misses a  super-blow! 26... b2b7  27. c7a5  27... h8g8  28. g4f4 Carlsen pushes his opponent further to  the ropes. 28... b7c6  29. a5d2  29... h7h6  30. d2d3  30... g8g7  31. d3a6 Nothing much to be done, so  this pawn is captured. 31... c6a6  32. e2a6  32... b8b2 This is more  accurate than the immediate recapture.
