Notes by Boris Schipkov

1. d4 e6 2. c4 Nf6 3. Nc3 d5 4. cxd5 exd5 5. Bg5 Be7 6. e3 O-O 7. Bd3 Nbd7 8. Qc2 Re8 9. Nf3 Nf8 10. h3 c6 11. O-O-O!
I like to attack.
11...a5 12. g4 a4 13. Nxa4!
A simple, but strong move.
13...Qa5 14. Nc3 b5 15. Bxf6! Bxf6 16. g5 Be7?!
Better is 16...Bd8 with some compensation for a pawn.
17. Ne5! Bb7
In the game Schipkov, B - Ishemchuzhin, Krasnodar tt 1984 (1-0, 65) Black played 17... Bxg5 18. Nxc6 Qc7 19. Bxb5. Here better was 19. Nxd5 Qb7 20. Ndb4 Bd7 21. Be4 or 19...Qd6 20. Ndb4 Bb7 21. Rhg1 Bf6 22. a3 Rec8 23. d5 with a huge advantage. Or 18... Qb6 19. h4 Bd8 20. Nxd5 Qb7 21. Kb1 Bd7 22. Ndb4 Ba5 23. Nxa5 Rxa5 24. d5, Mohr, S - Meister, P, Bundesliga 1996 (1-0, 46).

18. Bxh7+!!
The nice sacrifice was unexpected for my opponent. This beautiful blow leads to victory in all variations. (Ho-ho...)
18...Nxh7 19. g6 Rf8
If 19... fxg6 then 20. Qxg6 Nf8 21. Qf7+ Kh7 22. Qh5+ (22. Rhg1 Bf6 23. Rxg7!! Bxg7 24. Rg1 Ne6 25.Rg6) 22...Kg8 23. Qf7+ Kh8 24. Rhg1 Bf6 25. Rxg7!! Bxg7 26. Rg1 Ne6 27. Rg6 Rf8 28. Rh6+! 1-0, Black resigned in Ruban, V - Lalic, B, Jyvaskyla 1991. Or 21... Kh8 22. Rdg1 Bf6 23. Rxg7!! Bxg7 24. Rg1 Ne6 25. Rg6 Rg8 26. Rxe6 Rgf8 27. Rh6+ Bxh6 28. Ng6 checkmate, 1-0, Black resigned in Hellegaard, C - Johansen, M, Nordre Efteraar 1998. A crushing defeat!
Unfortunately, probably all these are human dreams. I saw in the "Queen's Gambit Orthodox, Exchange D31/D35-D36" by Thomas Henrihs (ChessBase) that Fritz has found the good defence 20...Kh8 (Boris Schipkov, 25.10.2004).
20. gxf7+ Rxf7 21. Nxf7 Kxf7 22. Qxh7 b4 23. Rhg1 Bf6 24. Ne2 Qxa2 25. Nf4 Qc4+ 26. Qc2 Bc8 27. Kd2!
The rest was pretty simple.
27...Qxc2+ 28. Kxc2 g5 29. Nd3 Bxh3 30. Nxb4 Bf5+ 31. Nd3 Rb8 32. Kc3 Be4 33. Nc5 Bf3 34. Ra1 Rc8 35. Ra7+ Kg6 36. b4 g4 37. Nd3 Kf5 38. Rga1 Rh8 39. R1a6 Rh2 40. Rxc6 g3 41. Rf7 Kg5 42. Rfxf6
Black resigned. 1-0
