Sicilian Defense: Closed
White develops the queenside knight without immediately exchanging the d-pawn. The center can remain intact while White prepares a kingside setup and Black challenges the center or expands elsewhere.
Your plan as White
Develop quickly and decide whether to open the center with d4 or choose a specific anti-Sicilian structure.
The opponent’s plan
The c-pawn challenges d4 from the flank. In open lines, use the semi-open c-file and prepare central counterplay.
Watch out: A kingside pawn storm needs a concrete calculation of threats. Black's queenside activity can arrive first.
