Most complex sicilian variation for black

[usachessmasterny]

After making books for about 2 years and editing them with the help of friends I just recently wondered when making a book what is the hardest sicilian variation to master in your engine games and book making I personally believe that if it comes to be the Sicilian Poisoned Pawn is by far the hardest because of all the fake evaluations from engines, I would like to know your oppinions on the most complex sicilian variation

I truely tend to distrust the Sicilian Dragon variation. There are far too many ways to pull off a large Kingside attack against Black.
