Meeting the sicilian?

Here's my suggestion: allow main lines, and then play some theoretical novelties. For example, most of your games will end up in the Najdorf, so play the Adam's Attack:

This move is fairly uncommon, but has its fair share of followers. It has gained good results and is very respectable.

Against other lines, use a database to find somewhat rare moves and then look up the theory, either on chess.com or another site.

You can also play open sicilian lines with Be2, 0-0 and maybe Be3 and a later f4.

Gawain Jones has also issued an antisicilian book based on the trio Rossolimo, Moscow, KIA, which is very good.

If you'd like to learn more about the Rossolimo and Moscow antisicilians, you're more than welcome to join the Bb5 Sicilian group.
