Chess Opening Theory/1. e4/1...c5/2. Nf3/2...d6/3. d4/3...cxd4/4. Nxd4/4...Nf6/5. Nc3/5...g6/6. Be3/6...Bg7/7. f3/7...O-O

= Sicilian Defense, Dragon Variation, Yugoslav Attack = The Yugoslav Attack continues with 7...O-O. In the Yugoslav, Black castles kingside while White castles queenside, leading to an opposite-side-castling game where speed is important. Black often pushes on the queenside with a5 and b5 and continues advancing those pawns, while White plays g4 and h4 and continues advancing those pawns. The fianchettoed bishop on g7 is a key piece in Black's attack on the kingside and what makes the Dragon the Dragon.

White's most popular continuation is 8. Qd2, preparing for a queenside castle.

Second is 8. Bc4, which often transposes to the main line.
