The Sicilian Defence: 1.e4 c5 2.Nf3... 5.c4 arises after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.c4 and falls under ECO code B36. By playing 5. c4, White establishes the Maroczy Bind, a pawn formation on c4 and e4 that severely restricts Black's ability to achieve the liberating ...d5 break that is central to Sicilian strategy. Denied this key advance, Black often faces difficulties coordinating pieces due to the spatial deficit, particularly in the center and on the queenside, and may need to resort to dynamic pawn breaks like ...b5 or ...f5 for counterplay, or else settle into a more restrained position. The Maroczy Bind is a major reason why the Accelerated Dragon sees limited play at the master level: rather than the sharp, double-edged battle of the mainline Dragon, it tends to produce slower maneuvering games where White holds an inherent positional edge. That said, modern analysis has shown that Black can reach equality with precise play, which has made this one of the most deeply studied and theoretically demanding variations in all of chess. With 1.4 million Lichess games across all rating levels, it is a well-established opening choice.

Common Mistakes to Avoid
