1. d2d4  1... d7d5  2. c2c4  2... d5c4  3. e2e4  3... b7b5  4. a2a4  4... c7c6  5. a4b5  5... c6b5  6. b1c3  6... d8b6 Nakamura did not mind repeating a line which Aronian used at the first Grand Prix event that took place in Berlin as well. 7. c3d5 The most aggressive move. It should be noted that not only did the white pieces rapidly create threats while developing, but they were moved in a very rapid speed by their commander too. 7... b6b7  8. c1f4  8... e7e5 A key resource, to bring the idle pieces out. 9. f4e5  9... b8d7  10. e5f4  10... g8f6 Black needs to sacrifice the exchange but at least is gaining the initiative back. 11. d5c7  11... e8d8  12. c7a8  12... b7e4 Another important, subtle move that destroys White's coordination. 13. g1e2  13... e4a8  14. d1d2 It is, however, Aronian who fires a novelty again. This move is obvious and logical: White speeds up his development and makes sure he will castle properly this time. 14... f6d5 Nakamura played his next obvious developing moves quickly. 15. e2c3  15... f8b4  16. f1e2  16... h8e8  17. f4g3 However, from here on the American GM started burning time, whereas Aronian kept blitzing, in a most-annoying (for the opponent) manner. 17... d7f6  18. e1g1  18... f6e4 All of this is pretty obvious, and at a glance looks good for Black. 19. d2c2 But now what $2 To grab the pawn or to develop even further $2 19... c8f5 Nakamura opted for the second and created a concrete threat. This, however, has a flaw.... 20. g3h4 It is essential to move the bishop from the knight's attack. 20... f7f6  21. e2f3 A nice move $1 White is not afraid of the discovered attacks as he needs to untie the central knot. 21... b4c3  22. b2c3  22... g7g5 The bishop is trapped, but Aronian had something in mind. 23. f1e1  23... d5f4  24. c2a2 The queen makes it to the enemy king, with tempo. 24... a8b7 A sad necessity for Nakamura. 25. a2a7 Simple and strong. Aronian needs the enemy king on the back rank. 25... b7a7  26. a1a7  26... e8e6  27. f3e4  27... e6e4  28. f2f3  28... e4e2  29. h4f2 White's superb preparation and energetic middlegame play has netted him an extra exchange. 29... b5b4 But Nakamura never resigns without a fight and finds another chance. 30. c3b4  30... c4c3  31. e1e2  31... f4e2  32. g1h1  32... c3c2  33. f2e3  33... c2c1r  34. e3c1  34... e2c1 At least Black won some material back. It is still lost for him though, as the rook and the pawns are dominating. 35. b4b5  35... d8c8  36. b5b6  36... c8b8  37. d4d5  37... c1d3  38. g2g4  38... f5c8  39. a7f7  39... c8a6  40. f7f6  40... b8b7  41. h1g1 Avoiding the knight fork. 41... a6b5  42. f6f5  42... d3f4 At least consolidating as much as he can. 43. h2h4 But not for long... 43... b5d3  44. f5f6  44... d3b1  45. h4g5  45... f4d5  46. f6f8  46... d5b6  47. f3f4  47... b7c6  48. g1f2  48... b6d7  49. f8f7  49... d7c5  50. f2g3  50... b1g6  51. f7f8  51... c5e6  52. f8g8 The opponent's time-trouble made Aronian less attentive and this allowed Nakamura one last chance. 52... c6d6 A trap $1 53. g8a8 Fortunately for White, he spotted it and calmed down quickly. 53... g6b1  54. a8a1  54... b1e4  55. a1d1  55... e4d5  56. d1d2 Zugzwang. 56... e6c7  57. g3h4 The king infiltrates and finally Aronian managed to grind down his opponent. 57... c7e6  58. f4f5  58... e6c5  59. h4h5  59... d6e5  60. h5h6  60... c5e4  61. d2b2  61... d5c4  62. b2b4  62... c4d3  63. b4e4
