Listen Rick, I think you have misunderstood chess in general. It is your choice how to play against or every opening and how to use Theory. Specific in the Sicilian if you don't like the heavy theoretical open games as playing White pieces there are several other alternatives, the so called Anti-Sicilians which offers plenty of opportunities for creative game. Yes you need to know ten-twelve moves theory for some of them but in general , you need to understand positional concepts and motifs. One of the good things in chess is to understand when and how you can play out of the main lines.
Don't get obsessed from the myth of any kind of opening, just dive in and play. The Sicilian is one more opening choice with pros and cons, nothing to be scared off.
First let me say that it is sound and that it works.
My observation is that everything is so shop worn about it that I don't see how there could be any fun in it. It is more like a religion than a chess opening. Players who use it tend not to use anything else. There are a million variations and Sicilian players know them all 30 moves deep. That is all that they do, after all. I know. I know. That means that you have to study 30 moves deep. Still, is it chess if you don't make your first unscripted move until the game is half over?
Sure, other openings have a dense catalogue of theory. But none of them seem so rigid and predictable. Whenever someone responds to e4 with c5, I just go ahead and resign. He didn't do anything wrong so he deserves to win. It's just that I play chess to play. I prefer to move on in the hope that the next guy wants to play too.
For the Sicilian fans out there: What is in it for you?
