You could either accept that black gets equality after 8. Nb3 (or 8. a3!? after which Qxb2?? traps the queen)
If you want to play the MAINLINE 8. Qd2!, either Experts vs. the sicilian (9. Nb3), which is slightly outdated (all books on PP is outdated after a week, but people under master level shouldn't care).
I think PP was almost refuted by 8. Qd2 Qxb2 9. Rb1 Qa3 10. e5!, but maybe black have improved (since it was on 2007 or 2008 I think).
I know pfren will be against me, but if you don't like giving pawns away, I recommend playing a gambit. I used to hate unclear sacrifices, then I read Mayhem in the Morra, and only played the Morra gambit against the sicilian. A month after, I began to make unclear sacrifices, and now I am learning the open sicilian, in which I really recommend ¨7 ways to smash the sicilian¨ and ¨Sicilian Attacks¨ which is pretty much everything you need to know about sicilian middlegames. White has to make some unclear sacrifices in 6 Bg5 in order not to get outplayed by black. But if he does, black has alot of problems.
Playing against the Najdorf as white I go 6.Bg5 because it's the most...fun. I'm not really sure how to deal with the poisoned pawn variation though.
I don't like sacrificing pawns, and I'm not sure where white's compensation is because black appears to be rock solid.
I would like some suggestion and some tip on common plans of attack. I'll be playing this at like 1600-1800 level so I don't really need to know a ton of theory, just the common ideas.
