Common Mistakes to Avoid
- Neglecting development: In the Closed Sicilian: 1.e4 c5 2.Nc3... d6, it can be tempting to make extra pawn moves early on. However, falling behind in development can be punished quickly, especially in open positions where opponent pieces can find active squares.

- Playing without a plan: Each position in the Closed Sicilian: 1.e4 c5 2.Nc3... d6 demands a specific approach. Understand whether you should be attacking, defending, or maneuvering before making your move. Random moves lead to random results.
