Sicilian Defense: Modern Variations, Anti-Qxd4 Move OrderBETA
dxc5 is the only other alternative for white that keeps the position distinct from the usual Open Sicilian lines. However, after Qa5+ Nc3 Qxc5, the position remains balanced, and the pawn structure is identical to the main lines.
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.
