Brain....hurts....

Alright so the post title might be a little dramatic but I am having a hard time learning the ins and outs of the Najdorf.  I know it's very complex but still when I play online NOBODY wants to play into it!  I'm thinking of jumping straight to the chapter covering the variation of the opening that I see the most OTB.  The Karpov approach, while being very solid and forcing black to know what he's doing, is not something I have ever seen by players under 2000.  The 6.Bg5 or 6.Be3 lines are gonna be my main points of study for the rest of the week and hopefully some of the material will seem familiar as I have seen it at least in my own games.  Wish me luck...
