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!
