9. Bd2 Nf8
A novelty. In the game Shirov, A - Dreev, A, Moscow blitz 1993 Black played 9...Nf5 10. e4 dxe4 11. Nxe4 Be7 12. O-O-O Nf6 13. Bd3 g6 14. Bc3 O-O 15. h4 Qc7 16. Ne5 Nxh4 17. Ng5 Nf5 18. f4 b5 19. Qh2 b4 20. Bxf5 exf5 21. Nxh7 Ng4 22. Nxg4 fxg4 23. Rh1 g3 24. Qh6 bxc3 25. Nf6+ 1-0.
Or 9...Qe7 10. e4 dxe4 11. Nxe4 Nf5 12. O-O-O Nf6 13. Nxf6+ Qxf6 14. Bg5 Qg6 15. c5 Bc7 16. Ne5 Qh5 17. h4 Bd8 18. Qe4 O-O 19. Be2 Bxg5+ 20. hxg5 Qh4 21. f4 Rd8 22. Rh1 Ng3 23. Rxh4 Nxe4 24.

10. e4! dxe4 11. Nxe4 Nf5 12. Nxd6+ Qxd6 13. O-O-O Ng6 14. h4!

14...Nge7
Dangerous is 14...Ngxh4?! 15. Nxh4 Nxh4 16. Rxg7 Nf5 17. Rg4 h5 18. Bf4! Qe7 19. Rg1 with development advantage to White.
15. Bd3 f6 16. h5 Kf7 17. Rg4 b5?!
Better is 17...c5.
18. Bf4! Qb4 19. Rdg1 bxc4 20. Bxc4 Rg8 21. a3 Qb6 22. Nh4 Nd5 23. Nxf5 exf5 24. R4g3 a5
After 24...Qxd4? 25. Bd6! Be6 (25...Bd7 26. Rd1 Qe4 27. Qb3) 26. Rd3 Qb6 27. Rb3 Qd8 28. Rb7+ Ke8 29. Bc5 White wins.
25. Rb3

25...Qa7?
Also hopeless is 25...Qxd4? 26. Bxd5+ Qxd5 27. Rd1 Qe4 28. Rb7+! Ke8 29. Qd2 Qc4+ 30. Kb1 Qd5 31. Re1+ Kd8 32. Qc2 Bxb7 33. Rd1 Ke8 34. Rxd5 cxd5 35. Qc7. Correct is 25...Qd8 with a small advantage to White.
26. Bxd5+ cxd5 27. Qc6 Qa6
Or 27...Rd8 28. Rb6 Kg8 29. h6.
28. Qxd5+
More precise is 28. Qc7+! Ke8 29. Re1+ Be6 30. Rb8+ Rxb8 31. Qxb8+ Kf7 32. Qc7+ Ke8 33. b3! a4 34. Bd6 winning.

28...Be6?
The final mistake. Black must play 28...Qe6 29. Qc5 Ba6. Worse is 29...Qxb3? 30. Qc7+.
29. Rb7+ Ke8 30. Re1 Rc8+ 31. Kd2 Rc6 32. Qd7+
Black resigned. 1-0
