The Sicilian Defence: 1.e4 c5 2.Nf3... 3.d4 arises after 1.e4 c5 2.Nf3 Nc6 3.d4 and falls under ECO code B32. By pushing the d-pawn forward, White establishes a classical pawn center on e4 and d4, a powerful structure that threatens to seize significant space through a future d5 or e5 advance. Black must therefore disrupt this center, and 3...cxd4 accomplishes exactly that, which was the fundamental purpose behind placing the c-pawn on c5 in the first place. This natural exchange gives Black a central pawn majority while also opening the c-file for future use. With 52.8 million Lichess games across all rating levels, it is one of the most popular openings.
