Hello mate! The Sicilian is a very popular and very sharp defense. The most popular of its variations is the Najdorf ( 1.e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6). With 5...a6 you prevent the Bishop check at b5 and the Knights from moving to b5 as well. It also prepares for 6...e6, the main line of the "pure" Najdorf. This attacks the White Knight on d4 and you make an attack for the centre. The Sicilian Najdorf is a very solid line of play. You should check it out!
The Dragon variation (5...g6) Fianchettoes the f8 Bishop sniping the HUGE a1-h8 diagonal. This Bishop is known as the "Dragon's Flame" in this openning. The only reason I don't like the Dragon is because of the Yugoslav attack that White can unleash upon you( you can find information on that on the wikipedia link for the Dragon variation ). I'm not very good at chess and I get demolished by it.
For the other variations, you can find plenty of info at the link Erik gave you for Wikipedia.
Good luck mate!
Can someone tell me what is so special about the Sicilian Defense and how does it actually help black? What does Kaspovov like it so much?
