Jul-23-03  dicoAMS: i'm unable to go through the games please help.
Oct-11-04  AdrianP: What's the current state of theory in the 6. f4 Najdorf - it doesn't seem to be played much at top level anymore.

What's the recommended mainline: 6...e5 7. Nf3 Nbd7 ...?

Oct-12-04  acirce: <AdrianP> I think it had an upsurge when Nunn and Gallagher recommended it in <Beating the Sicilian>.. And yes, that would be the main line. 6..e5 7.Nf3 Nbd7 8.a4 Be7 9.Bd3 0-0 10.0-0 something like that. The pawn-grabbing 10..exf4 11.Bxf4 Qb6+ 12.Kh1 Qxb2 is dangerous but interesting.
Oct-12-04  AdrianP: Thanks <acirce> that's v. helpful. I noticed that Leko ventured an outing with this against Kasparov Leko vs Kasparov, 1999 but the game ended in a draw, but am surprised to see pretty much nothing else at top-level in the last 5 years.
Oct-12-04  Dick Brain: The line <acirce> gives as the main line is the main line given by NCO, and it is a fairly recent treatment (not worrying about Bc4 for White). There are many other contunuations that are still used, but that is the popular one when Black wants to steer into Boleslavsky hole positions. 6...e6 going to the Scheveningen is a very common move and 6...Qc7 intending ...g6 later is pretty popular. Also, I don't think either 6...g6 or 6...Nbd7 have been refuted.

IIRC 6. f4 got somewhat popular in the 1970's when some English players had some successes with it. Maybe <acrice> is right that 6. f4 had another surge in the 90's in some quarters, but not in these parts: I haven't seen anyone around here take it up. Still, you would or course be smart to have a little something prepared for somebody who has studied Beating the Sicilian.

Oct-12-04  AdrianP: Thanks <Dick Brain>, helpful as well. <Still, you would of course be smart to have a little something prepared for somebody who has studied Beating the Sicilian.> Is there any particular line you recommend?
Oct-13-04  Dick Brain: <AdrianP> Look at Browne's games with the B93 Sicilian here on for several good ideas on how to combat this as Black.
Oct-26-04  AdrianP: <Dick Brain> Thanks. As a token of gratitude here's a Velimorovic Attack Classic from Christiansens Rocking the Ramparts for your collection...!

Nunn vs C W Pritchett, 1986

Christiansen gives two more Velimorovic Attack Classics namely Szmetan v Garcia, Malaga 1976 and Boto v Bostic, Bosnia 2001 but I cannot find these either on this database or on my Megabase.

  Willem Wallekers: <farrooj: What's wrong with 6..e5 7Nf3 Be6?> 8. f5 & 9.Bc4
Aug-03-05  russep: I think that this variation favours white from the time 6.f4 is played. It seems solid for white and hard for black especially if white plays a4, and all of blacks counterplay must be in the centre.
Feb-05-06  BaranDuin: <acirce:The pawn-grabbing 10..exf4 11.Bxf4 Qb6+ 12.Kh1 Qxb2 is dangerous but interesting.>

Isn't 12. Qd4 better? Black can't take on b2 (Rfb1 traps the queen) and after ...Qxd4 13. Nxd4 Ne5 14. Bd5 White seems to have a space advantage.

Sep-17-08  hicetnunc: I've just played this line by accident in a blitz game - do you guys think it's viable for black ? : 6.f4 Qc7 7.Nf3 g6 8.e5 dxe5 8.fxe5 Ng4 9.Nd5 Qa5+ (not in database but it creates weaknesses) 10.b4 Qd8 11.h3 e6 12.Nc3 Qc7 13.hxg4 Qc3+ 14.Bd2 Qc7

You´re right about it not being very popular, ´tho it has kind of resurrected this year at GM (not super-GM generally) level, with goods results for white, you maybe want to look up at World Cup games.

Statistically the best way to respond to an early Najdorf f4 is with the classicals e6 or e5.

If the f4 is played in lieu of the traditional f3 beggining the English Attack the main line has been simplifying with exf4, but an early open game in Najdorf generally satisfies White´s better diagonals, so I would rather advice you taking the initiative with Ng4, a very good line for Black in rapid games(amongst other things because of the surprise factor), in long games it has a poor record due to the fact that the weaknesses that it created in white´s position are utterly defensible with some care and strategic instinct; in blitz/rapid games playing the Ng4 line usually means going ahead in the clock, and we know how important is that!
