1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nd7 ( { Two other main lines are } 4... Bf5 ) ( { and } 4... Nf6 ) 5. Ng5 $5 { This somewhat  original move (the knight makes
the second move in a row in the opening) is GM Igor Zaitsev's idea. } 5... Ndf6 ( { There is a nice tactical basis for 5.Ng5; if } 5... h6 $2 6. Ne6 $1 fxe6 $4 7. Qh5+ g6 8. Qxg6# ) ( { Though the more popular alternative is } 5... Ngf6 ) 6. Bc4 e6 7. N1f3 h6 $5 { This move is a bit provocative. Black invites his
opponent to sacrifice a piece. } 8. Nh3 { But White prefers more quiet play.
Maybe the young Karjakin with his coach (unfortunately I don't know who his
coach is ) prepared an improvment in the following extremely sharp line: } ( 8. Nxf7 $5 Kxf7 9. Ne5+ Ke8 10. Qd3 Ne7 11. O-O b5 12. Bb3 a5 13. a4 b4 14. Re1 Ra7 15. Qh3 Rh7 16. c3 g6 17. Bc2 Rg7 18. Qxh6 $40 { with a very strong
attack, and White won in the game Rogovsky - Piankov, Ukraine 2001. } ) 8... Bb4+ { This is a novelty. } ( 8... Bd6 9. Qe2 Ne7 10. Bd2 Qc7 11. O-O-O b5 12. Bd3 a6 13. Rhe1 Bb7 14. g3 c5 15. dxc5 Qxc5 16. Ne5 Qxe5 17. Qxe5 Bxe5 18. Rxe5 Ng4 19. Rc5 Nxh2 20. Be2 Bf3 21. Bxf3 Nxf3 $13 { Huebner - Karpov, France 1988. } ) 9. Bd2 Bxd2+ $6 { I think the
exchange of dark-squares bishops is in White's favour because Black has some
problems with development of his second bishop. Also the d6-square can become
weak. } 10. Qxd2 Ne7 11. O-O-O O-O 12. Rhg1 { White prepares the adavnce of the g-pawn. } 12... Ned5 13. Bd3 Ng4 14. Ne5 $1 { The correct decision: White wants to exchange the knight on g4 and drive away
the knight on d5. And bishop c8 is off-side still. } 14... Qh4 15. c4 Nxe5 16. dxe5 Ne7 17. f4 Nf5 18. Be4 { Now White's advantage is obvious. He has the
d-file while Black has big problems with his bishop on c8. } 18... c5 $5 { A double-edged move: the knight f5 gains the excellent d4-post, but the bishop
on e4 now becomes even stronger. } 19. Nf2 Nd4 20. Nd3 Qxh2 $5 { Black wants to suffer at least for a pawn. There's  a small trap also. } 21. Kb1 ( { Here it is: } 21. Nxc5 $6 Qxf4 $1 22. Qxf4 Ne2+ 23. Kb1 Nxf4 $11 ) 21... Qg3 22. Rh1 Rb8 23. Nf2 { White begins hunting for the queen on g3, but maybe better was } ( 23. Rde1 { with the same threats (Rh3 and Nf2), for example: } 23... f5 24. exf6 Rxf6 25. Nxc5 Nc6 26. Nd3 $16 ) 23... f5 { The only defense against 24.Rh3. } 24. exf6 e5 $2 ( { Why not } 24... Rxf6 { attacking the f4-pawn? } ) 25. Nd3 { White has a good alterternative: } ( 25. Bd5+ Be6 ( 25... Ne6 $2 26. f5 $18 ) ( 25... Kh7 26. fxg7 Bf5+ 27. Kc1 Kxg7 28. fxe5 $18 ) 26. Bxe6+ Nxe6 27. fxe5 Qxe5 28. fxg7 Qxg7 29. Rxh6 ) 25... exf4 26. fxg7 Qxg7 27. Nxc5 { Now Black loses his only plus - the strong position of the knight d4. } 27... Nf5 28. Qxf4 Qg3 29. Qxg3+ Nxg3 30. Bd5+ ( { Of course not } 30. Rxh6 $2 Nxe4 31. Nxe4 Bf5 32. Re1 Rfe8 33. Rh4 Rxe4 34. Rhxe4 Re8 $19 ) 30... Kg7 31. Rhe1 b6 32. Ne6+ Bxe6 33. Rxe6 Rbe8 34. Rde1 Rxe6 35. Rxe6 { White is a pawn up, and in such open positions with pawns on both sides a
bishop is usually stronger than a knight. } 35... Rf7 36. a4 Nf5 37. Ka2 Rf6 38. Re8 a5 39. Ka3 h5 40. b4 { White's main task is to create a passed pawn on the queen side. } 40... Rd6 41. bxa5 bxa5 42. Ra8 Ne3 43. Rxa5 1-0
