As is usual with these sharp positions, much depends on the specifics. But in addition to the methods of attack that you mention, Black should be on the look-out for a favorable ...d5, usually achieved with the moves ...Qc7, ...b5 (-...b4), ...Bb7 and ...Kte5.

I wouldn't consider that to be a problem. I'm sure that there are many Najdorf players here who would kill for an extra tempo against the English Attack.

It's basically an English Attack (1. e4 c5 ; 2. Ktf3 d6 ; 3. d4 cd ; 4. Ktxd4 Ktf6 ; 5. Ktc3 a6 ; 6. Be3 (or 6. f3) e6 with the extra move ...h6 for Black. This will come in useful for him after White's inevitable g4 thrust, but of course, he must forget about castling for the forseable future. Since I don't play this with either colour, and tactics abound, I can't give any specific variations but any relatively recent book on the Najdorf will supply you with sufficient theory to play the positions a tempo up. The strategies for both sides are quite clear : relentlessly hack your way towards the opposite King. Anyway, this is the reason why 10. f4 is normally played.

can someone help me?

1.e4 c5 2.Nf3 d6 3.d4 cd 4.Nd4 Nf6 5.Nc4 Nc6 6.Bg5 e6 7.Qd2 a6 8.0-0-0 h6 9.Be3 Be7 10.f3(instead of the usual f4). I only won once out of eleven games in this line!! Can someone tell me how to play this? Thanks!
