The Sicilian Defence: Fighting Back Against 1.e4
Why 1...c5 is the most popular reply to 1.e4, the main ideas behind the Open Sicilian, the Najdorf and the Dragon, and how to meet the Alapin.
When White opens 1.e4, the most popular reply among strong players is 1...c5, the Sicilian Defence. It's been the choice of world champions from Fischer to Kasparov because it gives Black an unbalanced position and real winning chances, not just equality.
Why 1...c5?
Instead of copying White with 1...e5, Black controls the d4 square from the side with a flank pawn. The idea is a trade: if White plays d4 and Black captures with ...cxd4, Black swaps a side pawn for one of White's central pawns. Black then has two central pawns (d and e) against White's one, and a half-open c-file to use for rooks and the queen.
White gets something in return: faster development, more space, and attacking chances against Black's king. The result is an asymmetrical position in which both sides have their own plans, which is exactly why it's so popular when you need to win.
The Open Sicilian
White's most ambitious answer is to open the centre at once:
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3
This is the starting point of the main lines. White has a lead in development and a knight in the centre; Black has the extra central pawn and the c-file. Black's fifth move decides which variation you're in.
The Najdorf: 5...a6
The most famous Sicilian of all. The little move ...a6 stops White's pieces from using b5 and prepares ...e5 or ...b5 to gain space on the queenside. It looks slow, but it keeps Black's options open. The Najdorf is deep and heavily analysed, so it rewards study, but its ideas are simple to start with: control d5, expand on the queenside, and counterattack on the c-file.
The Dragon: 5...g6
Black puts the bishop on g7, where it aims down the long diagonal at White's queenside. The pawn chain d6, e7, f7, g6, h7 was thought to look like a dragon's back, which gave the line its name. White often answers with the Yugoslav Attack: Be3, f3, Qd2, castling long, and then pushing h4 and h5 to open the h-file against Black's king. Black castles short and attacks on the other side. Both sides race, and the first attack to land usually wins.
Other second moves for Black
- 2...Nc6 develops a knight first, leading to lines like the Classical Sicilian or the Sveshnikov (with an early ...e5).
- 2...e6 keeps the position flexible, leading to the Taimanov, Kan or Scheveningen systems, where Black builds a compact "hedgehog" of pawns on the sixth rank.
Anti-Sicilians: when White avoids the main lines
Many club players as White don't want to learn the Open Sicilian theory, so you'll often meet these instead:
- The Alapin, 2.c3. White prepares d4 so that after ...cxd4 they can recapture with the c-pawn and keep two central pawns. Black's simplest answers are 2...d5, hitting the centre at once, or 2...Nf6, attacking e4.
- The Closed Sicilian, 2.Nc3 followed by g3 and Bg2. A slower setup aiming for a kingside attack with f4 later. Black often plays ...g6, ...Bg7 and expands on the queenside.
- The Grand Prix Attack, 2.Nc3 and 3.f4. An aggressive kingside setup. Black should develop quickly and look to strike in the centre with ...d5.
- The Smith-Morra Gambit, 2.d4 cxd4 3.c3. White gives a pawn for rapid development. Black can accept and develop carefully, or decline with 3...Nf6 or 3...d5.
Common plans for Black
- Use the c-file. A rook on c8 and the queen on c7 put pressure on c2 and White's queenside, especially when White has castled long.
- The ...d5 break. When Black can play ...d5 safely, the centre opens on Black's terms and the opening is usually a success.
- The exchange sacrifice on c3. A classic Sicilian idea: giving a rook for White's knight on c3 to wreck the pawns in front of White's king or win the e4 pawn.
Is it right for you?
The Sicilian suits players who like complicated, double-edged positions and are willing to learn some theory. If you're just starting out, 1...e5 teaches the basics more gently. Once you know the opening principles and are comfortable with tactics, the Sicilian is a great way to play for a win with Black.
Practise it
Set the computer to Medium and play 1...c5 against 1.e4. Don't worry about names; focus on the plans. After each game, check the move list: did you get your ...d5 or ...b5 in? Did your rook reach the c-file?
