The Sicilian Dragon is a popular chess opening that arises from the Sicilian Defense. It is characterized by the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6. This setup allows Black to develop a strong pawn structure and control the center while preparing to fianchetto the dark-squared bishop. The name "Dragon" comes from the resemblance of Black's pawn structure to the shape of a dragon. This opening is known for its aggressive nature, often leading to sharp tactical battles. Players like Garry Kasparov have famously employed the Sicilian Dragon in high-level competitions.
