Sicilian Defence: the main ideas of 1.e4 c5
The Sicilian Defence, 1.e4 c5, is the most popular answer to 1.e4 at every level. Instead of copying White, Black fights for the d4 square from the side and creates an unbalanced game in which both sides can play for a win.
Fischer and Kasparov played it throughout their careers.
The Open Sicilian and the Najdorf
White’s main plan is to open the game with 3.d4. Black trades the c-pawn for White’s d-pawn: Black gets an extra centre pawn and the half-open c-file, White gets a lead in development and more space.
The Dragon
In the Dragon, Black puts the bishop on g7, where it looks down the long diagonal towards White’s queenside. The most dangerous answer is the Yugoslav Attack: White castles long, and both sides storm the other’s king with pawns.
Plans to remember
- Black plays on the queenside and in the centre: the half-open c-file, …b5, and the break …d5 when it works.
- White uses the extra space and often attacks the king, especially after castling on opposite sides.
- Every move counts: the Sicilian is sharp, and one slow move can decide the game.
Exercise: the Dragon trap
After 6.Be3 Black played the tempting 6…Ng4?, attacking the bishop. White to move: win a piece.
Make the move on the board: drag a piece, or click it and then a square.
Solved!
7.Bb5+! If Black blocks with 7…Bd7, that bishop is pinned to the king and can no longer take on g4, so 8.Qxg4 wins the knight. Taking at once, 7.Qxg4?, would lose the queen to 7…Bxg4.
Key points
- The Sicilian, 1.e4 c5, fights for d4 from the side and leads to unbalanced, sharp games.
- In the Open Sicilian Black gets an extra centre pawn and the c-file; White gets space and quick development.
- The Najdorf (5…a6) and the Dragon (5…g6) are its most famous lines.
