Nowadays  people are often finding nothing better than this in order to fight the  Berlin. The arising positions can also result from an Exchange French or  Petroff. 14... f7f6  15. c1d2  15... d8e8  16. e1c1 With the idea is to swap off the dark-squared bishop.  16... e8f7  17. d2f4  17... c6e7  18. f1g3  18... d6f4  19. c1f4 The position is not as innocuous as it seems. A.  Karpov had once won similar one against V. Kortschnoi in their match in  Merano. 19... f5d6  20. a1e1  20... a8e8  21. h2h3  21... e7g6  22. e1e8  22... f7e8 Nakamura played carefully enough,  traded the last pair of rooks and expelled the white queen from the active positon. The game is approximately equal now and both players continue to  maneuver trying to outplay each other. 23. f4c1  23... d7b5  24. d3c2  24... a7a5  25. b2b3  25... b7b6  26. a2a4  26... b5c6  27. c2d3  27... c6b7 Black keeps the bishop on the long diagonal. 28. g3f1  28... g6f8  29. f1e3  29... f8e6  30. c1c2  30... g7g6  31. g2g3  31... c7c5 Black decided to initiate some central pressure, but this is  risky. The d5 pawn may become a target. 32. h3h4  32... e6g7 Solid. 33. c2c1  33... e8e6  34. d3f1  34... e6e7  35. e3g2  35... g7e6  36. g2e3  36... e6g7  37. f1h3  37... g7e8  38. f3e1  38... c5c4 The idea is to create a weakness on a4, but  this is dubious for a concrete reason. 39. c1a3  39... c4b3  40. a3b3 This obvious move is not optimal. 40... d6c4 Regrouping nicely. 41. e1g2  41... e8d6  42. e3c4  42... d6c4  43. b3b5  43... g6g5  44. h3g4  44... g8g7  45. g1h2 Stepping out of the possible check on the first rank.  45... e7c7  46. g4e2  46... b7c6  47. b5b3  47... c7d7  48. b3b1 Karjakin understands well that the  passive defense is not good. 48... c6a4 Obvious, and wrong! 49. h4g5  49... f6g5  50. e2c4  50... d5c4  51. b1b6  51... d7f5  52. b6c7 Karjakin misses a  golden chance. 52... a4d7  53. c7c4  53... f5f2 With both the kings weak and with the queens  still on the board the most likely result should be a draw. 54. c4c5  54... f2f5  55. d4d5  55... a5a4  56. c3c4  56... h7h5  57. c5d4  57... f5f6  58. d4a7  58... f6f5  59. a7e3
