Common Lines in the Sicilian Defense

The Classical Sicilian (reached from many move orders, such as 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Nc6) is one of the soundest lines of the Sicilian for Black, if not always the most enterprising. White has several options beginning on the sixth move, such as the Richter-Rauzer Attack and the Sozin attack.
