Sicilian Defense

The Sicilian Defense begins with 1.e4 c5, the most popular response to 1.e4 at all levels. Black fights for the center asymmetrically from the start, creating imbalances that lead to dynamic, double-edged positions; White typically launches a kingside attack while Black counterattacks on the queenside.
