Petroff defense
1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. Nc3
This new relative move, aiming for rapid development – crude, but effective, which is being played very commonly against the Petroff defense in the last
years. In 2005, more than 50 games were played by players with a higher rating than 2500 ELO (5. d4 d5 is the main line. White will have to play c2-c4
later which lead to an isolated central pawn. 6. Bd3 Be7 7. O-O Nc6 8. c4 Nb4 9. Be2 O-O 10. Nc3 Bf5)
5. ... Nxc3 6. dxc3 Be7 7. Be3
This is one of the key positions. White must choose between Be3 or Bf4. (7. Bf4 O-O 8. Qd2 Nd7 9. O-O-O Nc5 10. Kb1 Bf6 11. Be3 Ne4 12. Qd5 Re8 13.
Bc4 Re7 14. Bd3 c6 15. Qh5 d5 16. Nd2 Re5 17. Qf3 Bf5 18. Bxe4 Bxe4 19. Nxe4 Rxe4 20. Qxe4 dxe4 21. Rxd8+ Rxd8 22. Bxa7 Be5 23. Bb6 Rd5 24. c4

(2534) BCCA-100 GM Section 15.05.2006 game still in progress.)
7... Nc6 8. Qd2 O-O
Black chooses an alternative with opposite side castling. Instead, Be6 or Ne5 are possible.
9. O-O-O Ne5
This is a typical position in this opening
10. Kb1
Topalov played against Kramnik 10. h4, but after 10. ... Bg4 11. Be2 Qc8 12. b3 Re8 13. Kb1 Bf8 14. h5 a6 15. Rde1 b5 the position was equalised.
10. ... Be6
Naidisch-Bacrot, Dortmund 2005, went on in the following way: 10. ... Bf6 11. Nd4 Nc6 12. h3 Nxd4 13. cxd4 Bf5 14. Bd3 Bxd3 15. Qxd3 Re8 16. Rhe1
Qd7 17. g4 g6 18. g5 Bg7 19. h4 Qg4 and Black is in a good position.
11. Nd4 Bd7
Tseshkovsky-Motylev, Moscow 2005, went on with 11. ... Nc4, but White got a better position some moves latter.
12. f4 Ng4 13. Bd3
13. Bg1 Re8 14. h3 Nf6 15. Bd3 d5
13. ... Re8
Nxe3 is also possible.
14. Rhe1 c5 15. Nf5 Bf8 16. h3
16. Bg1 Qf6 17. Ng3 Qh4 18. Ne4 Bc6 19. h3 Nf6 20. Bf2 Nxe4 21. Bxe4 Qf6 22. Bxc6 bxc6
16... Nxe3 17. Nxe3 Qh4
The position is balanced.
18. Nd5
18. Nf5 Qf6 19. g4 Rxe1 20. Rxe1 Re8
18. ... Rxe1 19. Qxe1 Qh6
It is possible for Black to play instead 19. ... Qxe1 20. Rxe1 Re8 21. Rxe8 Bxe8, simplifying the position, but Black considered that it was too early to
play for a draw...
20. Qh1
20. Qf1 Re8 21. Qf3 Qh4 22. a3 would have been better for White
20. ... Re8 21. g4 Qh4 22. Be4 h5
Black takes the initiative.
23. Bf3 hxg4 24. Bxg4
24. hxg4 Qxh1 25. Rxh1 Bc6 26. c4 Be7 This looks more logical for White, but it takes the queens off the board and White wanted to keep them on.
As things turned out much of the game's subsequent drama would have been lost if this sequence had been played.
24. ... Bc6 25. Bf3 g6 26. a3 Bh6
Finally, Black decided to play 26....Bh6, but 26....Bg7 is also possible.
27. Ka2
27. f5 gxf5 28. Nc7 Bxf3 29. Qxf3 Re1 30. Rxe1 Qxe1+ 31. Ka2 Qe4 32. Qg3+ Bg7 33. Qxd6 b6
27. ... Bd7 28. Bg4 f5 29. Bf3 Kg7
Black gets a better position in every move.
30. Kb1 b6 31. Nc7
31. Qf1 Bc8 (31. ... Bxf4 32. Qa6 Qxh3 33. Qxa7 Qxf3 34. Qxd7+ Kf8 35. Rd3 Qh1+ 36. Ka2 White stands slightly better.) 32. Bg2 Qg3 (32. ... Be6 33.
Nc7 Re7 34. Nxe6+ Rxe6) 33. Nc7 Re7
31. ... Rc8 32. Nd5 Bxf4 33. Nxf4 Qxf4
Black exchanges the two bishops advantage in order to play an endgame with one extra pawn in the king side, and bishops with the same color.
34. h4
This was the point behind 31. Nc7 for White, and led to useful counterplay. 31. Qf1 is equally effective.}
34. ... Rh8 35. h5 Be8
In the analysis "post-mortem", it could have been better for Black to play 35. ... Kf6 36. Qg2 g5}
36. Be2
36. Re1
36. ... Bf7 37. Qg1 Rh6 38. c4 Qe4 39. hxg6 Rxg6 40. Qf1 Qg2 41. Qe1 Re6 42. Qc3+ Re5 43. Bf3 Qg5 44. Ka2
44. Rxd6 Qe3 45. Qxe3 Rxe3 46. Bd5 Bxd5 47. cxd5 f4 Black stands better.
44. ... Qe3 45. Rd3 Qe1 46. Qb3 a6
46. ... Qh4 47. Bd5 Bxd5 48. cxd5 Qe4 (Maybe 48. ... Kf6 is better for Black.)
47. Rd1 Qe3 48. Qxb6 Bxc4+ 49. b3 Qxf3 50. Qc7+
Good move: White ensures to get a draw 50. Rxd6 Qc3 51. bxc4 Qxc2+ 52. Qb2 Qxc4+ 53. Ka1 Qf1+ 54. Ka2 Qe2 Black has a decisive advantage.
50. ... Bf7 51. Rg1+ Kf8 52. Qxd6+ Re7 53. Re1 Qb7 54. Qd8+ Be8 55. Qd6 1/2-1/2
