Been looking at the following recently: 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qa5 4.d4 Nf6 5.Nf3 c6 6.Bc4 Bf5 7.Bd2 e6 8.Nd5 Qd8 9.Nxf6+ Qxf6 10.Qe2 Bd6!? 11.O-O-O 0-0 [Alternatively 11...Bg4 may also be playable] Khalifman does not consider either of these fairly natural continuations in his otherwise thorough Opening According to Anand series, and they both seem perfectly viable to me.
Those are quite interesting and certainly both variations look quite interesting. I've analyzed about for a bit and didn't find any obvious refutation:
1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. d4 Nf6 5. Nf3 c6 6. Bc4 Bf5 7. Bd2 e6 8. Nd5 Qd8 9. Nxf6+ Qxf6 10. Qe2 Bd6 11. O-O-O http://www.france-echecs.com/diagramme/imgboard.phpfen=rnxxkxxr%2Fppxxxppp%2Fxxp... Line A I guess the obvious continuation for white after
11... Bg4 has to be
12. d5 Bxf3 13. gxf3 cxd5 14. Bxd5, when now black seems to have two main options
http://www.france-echecs.com/diagramme/imgboard.phpfen=rnxxkxxr%2Fppxxxppp%2Fxxx... Line A1 14...Nd7 15. Bc3 (15. Bxb7 Rb8 16. Qb5 O-O 17. Qxd7 Rxb7 18. Qxb7 Rb8 19. Qxb8+ Bxb8 20. Bc3 Qf4+ 21. Kb1 Bc7 22. Rd3 in comparison doesn't look that bad for black, I would prefer the two rooks though)
15... Be5 16. Bxe5 Qxe5 17. Qxe5 Nxe5 18. Bxb7 Rb8 19. Be4 which seeems just bad for black.
Line A2 The best continuation for black seems to be
14... Nc6 15. Kb1 15.Be4 Bf4 16. Bxf4 Qxf4+ 17. Qe3 Qxe3+ 18. fxe3 Ke7 is that actually okay for black? I am sort of inclinced to believe it.
15... O-O 15... Be5 looks not so good to me: 16. Be4
O-O (16... Bxb2 17. Qb5!) (16... O-O-O 17. Bxc6 bxc6 18. Qa6+ Kb8 19. Be3 Qe7 20. Qxc6 Qc7 21. Qa4 Bf6 is presumably just good for white) 17. Rhg1 Bxb2 18. Bg5 Qe5 (18... Qc3 19. Rd3 Qc5 20. Kxb2 Qb5+ 21. Ka1 Qe5+ 22. c3 f5 23. Bc1 fxe4 24. fxe4 Qxh2 25. Qg4 Rf7 26. Rh3 Qe5 27. Rh5 Qf6 28. Qh3 g6 29. f4 Rg7 30. Rh6 Rc8 31. Bb2 Rcc7 32. c4 Nd4 33. f5 exf5 34. exf5 Qb6 35. Rf1 Rxc4 36. fxg6 Rxg6 37.Rxg6+ hxg6 38. Rh1 is lost) 19. f4 Qc5 20. Kxb2 Qb4+ 21. Ka1 Qc3+ 22. Kb1 Qb4+ 23.
Kc1 Qa3+ 24. Kd2 Qa5+ 25. c3 f6 26. Bh6 Rf7 27. Qc4 Rd8+ 28. Kc2 Rxd1 29. Kxd1
Qh5+ 30. Kc2 Qxh6 31. Qxe6 Ne7 32. Rd1 g6 33. Bd3 and white is winning)
Of course the black position after 15...0-0 looks dangerous, after all, the open g-file must be worth something, but e.g. after
16. Be4 Rfd8 17. Rhg1 h6 I am not so sure how to use it, since tricks like
18. Bxc6 bxc6 19. Bc3 e5 20. Qe3 don't seem all that impressive (20.f4 Qxf4!). But maybe there is something here for white if one just gets the right idea?!
Line B To me
11...O-O looks in a way more solid (after all, after 11...Ld6 the whole 12.d5 break looks very dangerous to me, even if I cannot prove that it's really better for white).
Line B1 Black is able to set up a pretty quick pawn-storm, in part because of the bishop on c4:
12. h3 b5 13.Bb3 a5 14. a4 Nd7 15. g4 Bg6 16. h4 bxa4 17. Bxa4 Nb6 18. Bg5 Bf4+ 19. Kb1 Bxg5 20. hxg5 Qf4 21. Bxc6 Rfc8 22. Ne5 Rxc6 23. Nxc6 Be4 24. d5 Bxh1 25. Rxh1 Nxd5 26. Qd3 h6 27. gxh6 gxh6 28. Qd4 Qxd4 29. Nxd4 Line B2 Another idea I had was whether one could try to somehow play g2-g4 faster. Of course 12.g4 is just wrong, but maybe
12.Ne5 Bxe5 13.e5 Qg6 14.g4 E.g. 14...Bxc2 15.h4 Bxd1 16.Rxd1 h6 17.Bd3 f5 18.exf6 19.Qe4 g6 looks quite promising for white, but simply
14...Qxg4 seems to kill the whole idea.
