This  novelty should not have come as a surprise for Aronian. 14... a7a6 With the idea of c6-c5. 15. e5e6  15... c8e6  16. d4e6  16... f7e6  17. f1e1 The most natural reaction. Grischuk  needs this rook out. 17... e7f6 An active reply in return. 18. b2b3 Not a necessary move. 18... e8e7  19. f4c7  19... h8c8  20. c7d6  20... e7f7  21. d6c5 The outcome of the  opening is favorable for Grischuk. His pawn structure is healthier, and he will soon take under control the only open file. 21... c8d8  22. c5b6  22... d8d5  23. c2c4  23... d5d1  24. e1d1  24... f7e8  25. d1d6  25... e8e7  26. d6d3 From here on Aronian demonstrates amazing defensive  skills. 26... a8c8 The obvious idea is to lock up the white bishop with c6-c5... 27. b3b4 ...which Grischuk duly prevents. 27... e6e5 A  surprising decision. Black places a pawn on the color of his own bishop,  thus limiting it and turning it into a possible target. On the other hand, this is a weakness anyway, but Aronian is now gaining space for the king. 28. b6c5  28... e7e6  29. d3d6  29... e6f5 The point behind the advance is now evident.  Black's active king more than compensates for the weakening of the e-pawn.  30. c5b6  30... c8e8  31. g1f1  31... h7h5  32. f1e2  32... e8e6  33. d6d1  33... e6e8 Both sides make progress, but the impression is  that Aronian is closer to equality at this point of the game. 34. a2a4  34... f5e6  35. h2h3  35... f6e7  36. d1b1  36... e8f8  37. b4b5 Grischuk is still looking for a way to  break through, but now that the black rook gets out, it is only White who  is risking. 37... f8f4 Aronian plays for the win! 38. b5a6  38... b7a6  39. b1c1  39... c6c5  40. b6a5  40... f4e4 I strongly advise you to pay  attention on how many times Aronian will use the in-between checks in this game to disrupt the opponent's coordination. 41. e2d3  41... e4d4  42. d3e2  42... e5e4  43. c1c2  43... e7f6  44. a5b6  44... e6d6  45. b6a5  45... d6c6  46. a5d2  46... d4d3  47. a4a5  47... d3b3  48. d2e3  48... f6c3 Heading for the a5-weakness. 49. e3d2  49... c3b4  50. c2a2  50... g7g6 Placing the pawn on a light square just in case. 51. e2d1  51... b3d3  52. d1e2  52... d3d4 Finally Aronian wins material. 53. a2c2  53... b4d2  54. c2d2  54... d4c4  55. e2e3  55... c4a4  56. d2d8 But Grischuk activates his rook. 56... a4a5  57. e3e4  57... a5a4 One more of these. 58. e4e5  58... a4a2  59. d8d6  59... c6b5  60. d6g6  60... a2e2 One more in-between check. 61. e5d5  61... e2f2  62. g2g4  62... h5g4  63. h3g4  63... a6a5  64. g4g5 Grischuk pushes the passer instinctively in time trouble. 64... a5a4  65. g6g8  65... f2d2 One more! 66. d5e5  66... a4a3  67. g5g6  67... d2g2  68. e5f6  68... b5c4  Here Aronian could have won as in the game. 69. g8a8  69... c4b3  70. a8b8 Now White's active rook should have sufficed to  secure the draw. 70... b3c3  71. b8a8  71... g2f2  72. f6e7  72... f2e2  73. e7f7  73... e2f2  74. f7e7  74... f2e2  75. e7f7  75... a3a2  76. g6g7  76... e2f2  77. f7e7
