None of them. Too much to know and memorize. And the middlegames are not for me.
Which variation of the Sicilian do you play?
If you're about what i play with white - i dont play e4, my rating is ~1800 and i play Sicilian myself, if i play against it i will choose Alapin or Open (if you know theory)
Do you play the Open, Closed, or Alapin, or something else like the Smith Morra or the Wing Gambit? Personally, I play the Closed Sicilian Grand Prix.
