The positionWhat Sicilian Defense puts on the board
Material is level, with white to move.
White has central pawns on e4.
White can still castle either side; Black can still castle either side.
White’s planWhat White is trying to build
Use the lead in development before Black’s queenside structure becomes active.
Choose a clear setup: an open d-file after d4, or a slower closed kingside expansion.
Black’s planHow Black challenges it
Use the c-file and queenside pawn majority as active assets.
Finish development before starting pawn play on the wing.
The ideaThe tactical pattern to recognise
A rook or queen on the half-open c-file can attack c2.
Central breaks with d4 or …d5 often change the position at once.
The mistakeWhat to check before committing
Launching a flank attack while pieces remain on their original squares.
Allowing a central break to arrive with tempo on the queen or king.
