I love to play the Sicilian because it has such a dynamic nature. It is a good opening for attacking players. Positional players can find interesting variations such as the accelerated dragon (1. e4 c5 2. Nf3 Nc6 3. c4 cxd4 4. Nc3 g6) There are a good number of systems for Black to choose from: the Dragon, Schevieningen, Kan, Najdorf, Taimanov, Kalashnikov and so forth. The curious reader can look them up at http://en.wikipedia.org/wiki/Sicilian_Defence (Wikipedia is your friend)
White can cut across this strategy by playing Nc3 and d3 instead of Nf3 and d4, giving rise to the Closed Sicilian. Black has nothing to fear in these lines: in fact White's strategy is relatively unambitious so play is very even.
Having said that the Closed Sicilian gives rise to positions I personally don't enjoy, no matter how equal they may be, Most players on ChessConquest play the Closed Sicilian so I have stopped playing the Sicilian almost entirely.
Still, I would recommend anyone to try the Sicilian, especially if you can get an openings book or get some guidance on the Internet.
