I'm new to chess (picking up several books recently and spending a few months reading books; I've managed to go from 700 to average around 1400 on chess.com before coming here) and I'm having some issues understanding the Sicillian. I'd like to utilize it against E4 however I find it to be incredibly deep and sharp. I've shuffled through a few variations (Fianchetto variations like Dragon or Accelerated don't seem to play as nicely as the Najdorf where I particularly enjoy the Poisoned Pawn variation) however I have issues when it goes off the rails; for instance the Moscow variation suddenly makes me feel as if I've got the sharp end of the knife.
Does anyone have any good resources or advice on how to delve deeper into the Sicillian? (Prefered Najdorf variations but any is fine.) and how to play when things go off the rails? Possibly some good book recommendations that are geared towards intermediate players as opposed to Grand Masters (the few books I have are devastatingly complex)
