The idea is Bd7+Nc6, hence White usually retreats Nd4 to Nb3 sooner or later (Black also loses then a tempo: Qa5-c7). As I say on my previous post on this thread I believe this is a small victory for Black in comparison to the main line (Nd4 protects c2, threatens a few sacrifices and is easy to regroup if Black tries e5).

oh yes you are right!
so i think Nb3 without Bxf6 is the best option for white.

Hi Alexander (fellow Greek or do you live abroad?) - welcome to the forum!

B)8...Be7 9.Qg4! threatening both Qg7 and f5 (maybe).


Does not 8. Bxf6 gxf6 9. Bc4 Be7 10. Qg4 Qb4 win a piece? Is there sth I miss? Shocked

Hey guys!!
I think that the move 7...Qa5!?! is best met by 8.Bc4!?.Here is some of my analysis:  A) 8...b5 9.Bb3 Bb7 [9...b4 just plays into white's hands as black is very behind in development after 10.Nce2] 10.Qh5! with a crushing attack.

B)8...Be7 9.Qg4! threatening both Qg7 and f5 (maybe).

C)8...Bd7!? 9.f5! exf5 [9...e5 Qh5! exd4 10.Qxf7+ Kd8 11.Qxf6+ Kc7 12.Qxd4!! Qe5 13.Nd5+ Kd8 14.Qb6+ Ke8 15.Nc7+ Ke7 16.0-0-0! +-] 10.Qh5! +-

D)8...Nc6 9.f5!? Nxd4 10.Qxd4 Qe5! 11.Qxe5 fxe5 12.f6!! Bh6 13.Be2! Rg8 14.0-0 with a small edge for white.

I also believe that the Knight on d4 is a very dangerous piece = imo Nb3 is a small victory for Black

That's only true if the knight on b3 is better than on d4, something I dare to doubt.

At the very least white can take on f6, play Nb3 and be a tempo up on 7...Qc7 lines.

iirc King on the Bg5 chapter, while discussing the main line, quotes a famous game of Fischer that was included in 'My 60 Memorable Games' under the title 'Castling into it':

[Event "Yugoslovia Cand. Tourn."]
[Date "1959.10.22"]
[Round "25"]
[Result "1/2-1/2"]
[White "Svetozar Gligoric"]
[Black "Robert James Fischer"]
[ECO "B99"]

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Be7 8. Qf3 Qc7 9. O-O-O Nbd7 10. g4 b5 11. Bxf6 gxf6 12. f5 Ne5 13. Qh3 O-O 14. Nce2 Kh8 15. Nf4 Rg8 16. Rg1 d5 17. fxe6 dxe4 18. Nd5 Qc5 19. Nxe7 Qxe7 20. Nf5 Qxe6 21. Qh6 Bd7 22. Rd6 Nxg4 23. Rxg4 Qxf5 24. Rxg8+ Rxg8 25. Rxf6 Qd5 26. Rd6 Qf5 27. Rf6 Qg5+ 28. Qxg5 Rxg5 29. Rxf7 Bg4 30. Kd2 Bf3 31. Ke3 Rg1 32. Bh3 Re1+ 33. Kf4 Bd1 34. Ke5 e3 35. Bf5 Rg1 36. Rxh7+ Kg8 37. Rc7 Bg4 38. Bxg4 Rxg4 39. Rc3 e2 40. Re3 Rg2 41. Kd4 e1=Q 42. Rxe1 Rxc2 43. Rb1 Kf7 44. a3 Ke6 45. b3 Rxh2 46. Kc5 Kd7 47. Kb6 Ra2 48. Kxa6 Rxa3+ 49. Kb7 Kd6 50. Kb6 Kd7 51. b4 Rh3 52. Rc1 Rh8 53. Kxb5 Rb8+ 54. Ka4 Ra8+ 55. Kb3 Rc8 56. Rxc8 Kxc8 57. Kc4 Kb8 1/2-1/2 (nice frontal defence utilising the distant opposition in the end)

I seem to recall that King also uses the same catch phrase somewhere in the 6. h3 chapter (I bet it's right at the end of that chapter).

Witty book btw - King makes me laugh  Smiley

About 10. e5, I do continue to play against it, but someone needs to be quite prepared. The positions that arise are super-sharp and many times the correct continuation is counter-intuitive for a human brain. In almost all other lines of the Najdorf I use mostly common sense. In this particular sideline I use rote memorisation. But some of the most interesting games I have played were Bg5 Najdorfs with Danner's idea (and White choosing sth different from 10. e5)..

Fischer used to take with the g-pawn? I was unaware of this... And where did King say this?

Anyway, it's this recapture that was recommended in King's Winning with the Najdorf when he discusses Danner's idea. But maybe that's only because white has wasted a lot of time playing on the kingside so it's safe to stay in the center.

If you find 10.e5 more demanding then why do you play the "refuted" line? Or did I misunderstand you there?

I keep on playing the 'refuted' line and as far as I am concerned I'm not convinced it is refuted! (and yes I've read the relevant passage on Experts vs. the Sicilian).. Personally I find more demanding facing 10. e5 where you need to prepare a lot in advance (with a PC).

Your line has a distinctive difference: Black has to recapture with the g-pawn (either 8. BxNf6 or 8. Nb3 Qc7 9. BxNf6) and this is not my cup of tea..

Or as Daniel King has put it: 'recommended only for Fischer freaks!'

Najdorf: 6.Bg5 e6 7.f4 Qa5!?

Hello all,

I was wondering why I can't seem to find any theory about the following variation:

1.e4 c5 2.Nf3 d6 3.d4 Nxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Qa5!?

I've been playing this for some years now (every since 7...Be7 8.Qf3 Qa5?! was refuted by Radjabov), mainly because it's so unknown, but it has always struck me as weird that it's never mentioned anywhere. Is there some obvious disadvantage that I'm missing? Most of the time white will play his Knight to b3 (e.g. after Bd7 and Nc6) which is just an improvement on the main variations.

Anyone else has experience with this variation or knows why it's not mentioned in any book?

Thanks,

Joris
