The main line, move by move
The Najdorf (5...a6) is the most famous Sicilian. Here is a calm version for beginners. Step through it, then practice Black's moves.
How the Sicilian works
After the trade on d4, Black has two central pawns (d and e) against White's one (e). That's a long-term advantage. In return, White gets faster development and more space. The game is a race: White attacks the king, Black uses the c-file and queenside.
Black's plan
- Use the half-open c-file: rook to c8, pressure on c3 and c2.
- Expand with ...b5 and ...b4 to kick the c3 knight.
- Prepare the ...d5 break to free the position.
White's plan
- Use the extra space for a kingside attack (f4, f5, g4).
- Control the d5 square, especially after ...e5.
How to meet the Alapin (2.c3)
Many club players avoid the main lines with 2.c3, preparing d4. The best reply is to attack e4 right away with the knight.
Common beginner mistakes in the Sicilian
- Falling behind in development. The Sicilian is sharp; moving the queen or pawns too much gets punished.
- Creating a hole on d5. After ...e5, the d5 square can become a home for White's knight. Watch it.
- Castling into an attack without counterplay. Make sure your queenside play is fast enough.
