Sicilian DefenseBETA

White follows through and opens the center with d4, entering the Open Sicilian. White maximally controls the center temporarily, so black should capture this pawn immediately. The c1-bishop can develop next.

The Sicilian is a counterattacking game. By keeping the game asymmetrical, black wants imbalances in the position, which can eventually lead to a double-edged position with winning chances on both sides.

In the Open Sicilian, white has a lead in development and a stronger center. In return, black has two pawns in the center, and can eventually expand to take over the center. White often plays for a kingside attack, while black counter attacks against the queenside or after white over-extends during their kingside assault.
