Everything Sicilian

You might try starting here: http://en.wikipedia.org/wiki/Sicilian_Defence It gives some brief analysis of the main lines and ideas in most of the Sicilian variations.
I need to learn the Sicilian from both sides of the board. I feel that I play it poorly and play against it poorly. Please post your favorite Sicilan variations. You can show both sides by posting them on the forum chess board. Thanks!
