Which White stops, but now the other  idea works.
1. d2d4  1... d7d5 In a delicate match moment, Carlsen chooses to play a la  Nakamura. The American GM had won the first game as White and was doing  great in the second as well, probably missing a chance to increase his  lead. 2. c2c4  2... e7e6  3. b1c3  3... a7a6  4. c4d5  4... e6d5  5. c1f4  5... g8f6  6. e2e3  6... f8d6  7. f4d6 7.Bg5 is the modern continuation. 7... d8d6  8. f1d3  8... c8g4 A tricky idea and a promising side line. 9. d1b3  9... b8c6  10. h2h3  10... g4h5 Both Nakamura and Carlsen were once trained by  Kasparov, a man who had his seal of approval on the Queen's Gambit, and  this opening served him well all his life with both colors. Therefore,  White's next move is a bit puzzling. 11. g1e2 I do not like this  novelty at all. 11... h5e2 Because of this move, Carlsen did not hesitate to trade  his problematic bishop at once and to keep his valuable knights on board.  As Kasparov proved in his games, a super-knight on the d6-square is a  dream for the QGD player. 12. c3e2  12... e8g8  13. a1c1  13... c6d8 A nice maneuver. The knight is heading to the e6-square and  from there, depending on the circumstances, it can attack on the kingside  via g5, defend the queenside via c7, or continue maneuvering as in the  game. 14. b3a3 Nakamura is trying to distract his opponent from his  general plan: a kingside attack. 14... d6d7 Correctly avoiding the trade. 15. e1g1  15... g7g6 An useful move. 16. e2f4 Black's ideas are obvious and straightforward, whereas Nakamura's task is much more difficult. For the time being, he stops the Nd8-e6  maneuver. 16... f8e8  17. d3c2 And then keeps maneuvering. 17... c7c6  18. f4d3 That was the point, the knight makes it to the  e5-square. 18... d8e6  19. f2f4 Attacking a la Pillsbury. 19... e6g7 But Carlsen is ready. In fact this knight wants to keep moving towards  the d6 super-spot. 20. f4f5 Nakamura understands that if the game  continues in a slow mode, the knights will prevail, so he searches for  activity. This would have worked against most players, but Carlsen is as  cold as ice. 20... g6g5 It will be Black who attacks on the kingside. 21. d3e5  21... d7c7 The positional exchange sacrifice on e5 is in the air. 22. h3h4 This only helps Black. 22... g5g4  23. a3c3  23... g7h5 Now Black is in full control. Nh5-g3-e4 is a  strong positional threat.
