Sicilian Defense: Old Sicilian

Before the first move

The Sicilian Defense is a sharp, asymmetrical response to White's center control. By playing c5, you create an unbalanced position where White seeks quick development and space, while you aim for counter-attacks on the queenside and control over the d4 square. It is the most popular weapon for players seeking a win with the black pieces.

1. e4White

White plays e4, the most common starting move. It immediately controls d5 and f5 while preparing to develop the kingside. Black has many ways to respond, including the solid e5 (Open Game) or the French Defense with e6, but the Sicilian Defense with c5 is the most ambitious and fighting choice.

1... c5Black · your move

Push your pawn to c5. This move characterizes the Sicilian Defense, fighting for the d4 square without creating the symmetry of a king's pawn opening. You are preparing to trade your flank pawn for White's central d-pawn, which will eventually give you an extra central pawn and an open c-file for your rook.

2. Nf3White

White plays Nf3, preparing the standard d4 thrust to open the game. This is the main line, though White sometimes tries the Bowdler Attack with Bc4 or the Keres Variation with Ne2 to avoid the most theoretical lines. By developing the knight, White prepares to challenge Black's control of the center immediately.

2... Nc6Black · your move

Bring your knight to c6. This is the Old Sicilian, a flexible move that exerts pressure on d4 and e5. Unlike other variations where you might play d6 or e6 first, developing the knight here keeps your central pawn structure fluid and prepares to meet White's d4 push with active piece play.

Where you stand

The game is headed toward a classic Sicilian battle. White will likely play d4 to open lines, or Bb5 to pin your knight and slow down your development. Black's plan involves pressure on the c-file and maintaining a flexible center. Both sides must balance rapid development with the tactical dangers inherent in such an asymmetrical pawn structure.

• d2-d4 Challenge the center and open lines
• g7-g6 Prepare to fianchetto the dark-squared bishop
