Qh6 Be2 1/2-1/2 There is no reason to bail out from main line for black. The poisoned pawn is not poisoned anymore, all lines leads to draw. There are lots of chances or oppurtunities for black to go Wrong. Here Is a game i played long time back and was testing 19...Bf5 . I had tough time to draw the endgame which was draw.

These lines not consisting of bad moves, just being out of fashion. You can't do better than purchasing Nunn's The Complete Najdorf 6.Bg5. In all those years I only found one glaring mistake: Nunn evaluates Van der Wiel-Portisch, Tilburg 1983, as favourable for Black while it's equal. Van der Wiel should have played 29.Rb8+ Kg7 20.Ne8+ with a perpetual.
