1. e2e4  1... c7c5 For many years people were afraid to choose the Sicilian against Karjakin. Any Sicilian. But Naiditsch is fearless. 2. g1f3  2... b8c6  3. d2d4  3... c5d4  4. f3d4  4... e7e5  5. d4b5  5... d7d6  6. b1c3  6... a7a6  7. b5a3  7... b7b5  8. c3d5  8... g8e7 This move is the  main difference of the Kalashnikov, in comparison to the usual Sveshnikov  line. The knight is more flexible on e7 and it cannot be easily swapped  for the white dark-squared bishop. 9. c2c4  9... e7d5  10. c4d5  10... c6d4  11. f1d3  11... g7g6  12. e1g1  12... f8g7  13. c1e3  13... e8g8  14. e3d4  14... e5d4 Now we are  in a position which is more typical for the Accelerated Dragon. Or the  KID. 15. a3c2  15... c8d7  16. c2e1 Karjakin tries to improve on an earlier  game of Naiditsch. The knight is heading to the f3 square. White hopes  that he has enough time to regroup his troops and eventually win the  isolated pawn on d4. 16... d8b6  17. e1f3  17... a6a5 However, Naiditsch plays very energetically and  does not allow the aforementioned plan. 18. h2h3 This takes under control  the g4 square and avoids the possible pin after Bd7-g4. It's possible that Karjakin later regretted this move. 18... a5a4 In order to force a concession on the queenside. 19. d1d2  19... a4a3 Now Black secures a strong outpost on c3. The d4 pawn is not a weakness at all! 20. b2b3  20... a8c8  21. f1e1  21... f8e8 Black is very careful not to  allow central counterplay. 22. a1d1 White is ready to move the bishop away and grab the central  pawn. 22... c8c3 The rook is not just decorative there. It does  tremendous work. 23. g1h2 In order to defend the h3 pawn. The strong  influence of the rook is felt. 23... b6d8 A very neat move. Once again Naiditsch prevents the bishop motion. 24. b3b4  24... d8f6  25. f3g1 A sad retreat. 25... g6g5 This is it! Thanks to his active play Black managed to  build strong pressure on the dark squares. 26. g1e2 It seems Karjakin  will finally get rid of the annoying rook. 26... f6f2 But it did not even tremble. 27. d2g5 The only  defence. 27... h7h6  28. g5g3  28... f2g3  29. h2g3  29... e8e4 Spectacular. 30. e2c3 Not the best way to take the exchange. 30... g7e5  31. g3f2  31... e4f4 This rook survives and will play a key role  into the building of Black's initiative later. 32. f2e2  32... d4c3  33. d1b1  33... f4d4  34. b1b3  34... d4d5  35. e1d1  35... d7e6  36. b3a3  36... e5f6 Another nice maneuver. The rook finds the ideal  square. For the exchange Naiditsch got a pair of connected passers, a  pawn, the bishop pair. 37. d3c2  37... d5g5  38. e2f2  38... d6d5  39. a3a8 A typical time-trouble check. 39... g8g7  40. a2a4  40... d5d4 Advancing the passers is the primary goal for  Black. Plus, they advance with tempos here. 41. g2g4  41... e6c4  42. a4b5  42... g5e5 Naiditsch decides the game with direct attack against the  white king.
