The Sicilian Defence: 1.e4 c5 2.Nf3... Nf6 arises after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 and falls under ECO code B33. 4...Nf6 is a move which starts the conventional Sicilian counter attack.

Common Mistakes to Avoid
- Neglecting development: In the Sicilian Defence: 1.e4 c5 2.Nf3... Nf6, 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.
- Ignoring the opponent's kingside attack: In many Sicilian lines, White will castle queenside and push pawns toward your king. If you don't create counterplay on the queenside or in the center, White's attack will arrive first.
- Playing without a plan: Each position in the Sicilian Defence: 1.e4 c5 2.Nf3... Nf6 demands a specific approach. Understand whether you should be attacking, defending, or maneuvering before making your move. Random moves lead to random results.
- Forgetting about piece coordination: Chess pieces are strongest when they work together. A single piece attacking alone is easy to defend against, but coordinated pieces can create unstoppable threats.
