White is a clear pawn ahead and finishes the game  confidently.
1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... d7d5  4. b1c3  4... f8e7  5. c1f4  5... e8g8  6. e2e3  6... c7c5  7. d4c5  7... e7c5  In some sense a tribute to Kasparov, who mentored both Nakamura and  Carlsen at phases of their chess development. The 13th world champion  successfully implemented the QGD in his first matches against his great  predecessor on the throne, A. Karpov. 8. a2a3  8... b8c6  9. d1c2  9... f8e8  10. f4g5  10... c5e7  11. a1d1  11... d8a5  12. f1d3  12... d5c4 A novelty that allows a  deviation from the main line. 13. d3c4  13... h7h6  14. g5f4 Carlen decided to go off the beaten track as early as he could. He clearly understood that in comparison to another line of  the QGD, his opponent would have two extra tempi but saw no way for him to utilize on those. 14... c8d7  15. e1g1  15... a8c8  16. e3e4  16... e6e5  17. f4e3  17... c6d4 This was expected by White as he assumed that he would be  better if his opponent does not force matters. 18. e3d4 Now the forcing sequence follows: 18... c8c4  19. d4e5  19... d7a4  20. b2b3  20... f6e4 Missed by the world champion. 21. d1d3  21... e8c8 Up to here, Nakamura has defended with his usual  aggressive attitude, but this move is connected with a blunder. Everything is hanging, but White's next move reveals the reality. 22. c2b2 The queen steps out of the pins and finds an excellent vantage  point against the black king. At the same time, almost all black pieces  remain hanging. 22... e4c5  23. d3e3  23... a4b3  24. e5g7  24... c4g4 "A nice try" (Carlsen). 25. g7h6  25... e7f6 It seems as if Nakamura has managed to consolidate, but  Carlsen has foreseen it all. 26. f3e5  26... f6e5  27. e3e5  27... a5b6  28. b2d2  28... g4g6  29. h6e3 Now a familiar centralization happens. 29... b6c6  30. c3d5  30... b3d5  31. d2d5  31... b7b6
