The Sicilian Defense is a King’s Pawn Opening beginning with 1. e4 c5
Similarly to symmetrical King’s Pawn openings like the Ruy Lopez, black ensures himself of some central space by occupying the center on move one. But in the Sicilian Defense, black guarantees that the position will become imbalanced!
This has made the Sicilian Defense weapon a popular fighting weapon at all levels of chess for the past several decades.
Compared to 1…e5, the downside of the Sicilian Defense is that moving the c-pawn doesn’t really open up any lines for black’s pieces to develop (except for the queen, which often doesn’t want to develop too early). This means that white will often achieve a lead in piece development in the Sicilian Defense…but how can white exploit this?
White can try to open the center with an early d4, in an attempt to make use of their more active pieces…but there is a positional downside. If white plays d4, black will be able to exchange their c-pawn for white’s more central d-pawn, and obtain the long-term positional advantage of having two central pawns against one!
We’ll consider a few different approaches white can take against the Sicilian Defense:
Note that black has a couple options on move two. 2…d6 is popular, but so is 2…e6 and 2…Nc6. Various transpositions are possible between the three options, though there are many continuations that are specific to each.
The Open Sicilian is a highly complex opening with at least a dozen subvariations, and is certainly not a beginner-friendly opening – for either side! White accepts black’s challenge and opens the center right away, striving to make use of their development lead.
Some common themes in the Open Sicilian:
Let’s take a look at just one exciting, aggressive continuation to highlight how dangerous the Open Sicilian can really be!
1. E4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6
This is the popular Najdorf Variation of the Sicilian Defense. Playing an early flank pawn move like …a6 may seem in violation of the Opening Principles, but black wants to deny the b5 square to the white pieces and eventually expand with …b5 himself.
6. Be3 e5 7. Nb3 Be6 8. f3 Be7 9. Qd2 Nbd7 10. 0-0-0 0-0
The stage is set. White’s set-up, categorized by the early f3 and queenside castling, is known as the English Attack against the Najdorf Sicilian (yes, even the subvariations have subvariations!)
White wants to advance his kingside pawns towards the enemy monarch, and to do so without exposing his own king, white castles in the other direction. The f3 pawn does a good job of stabilizing the center as well as supporting the advance of the g-pawn.
11. g4 b5 12. g5 b4 13. Ne2 Ne8 14. f4 a5 15. f5 a4
Insanity! Both sides are racing full-speed-ahead towards the enemy king. It turns out that 16. Nbd4! is white’s strongest move here – temporarily sacrificing a piece, but after 16…exd4 17. Nxd4, black’s bishop is still under attack and white is threatening the powerful fork Nc6. White will regain the piece…in a highly imbalanced, double-edged position.
This is just one exciting, perilous variation of the Open Sicilian – consider yourself warned!
Compared to the thrills of the Open Sicilian above, the Alapin variation is much more friendly to those who don’t want to go down a rabbit hole of opening memorization.
White’s plan is sound and simple – white wants to play d4 next turn and grab the center, and if black exchanges on d4, white will be able to recapture with a pawn instead of a piece, white will be able to recapture with a pawn instead of a piece.
Against an unprepared Black player, this plan works great. My very first tournament chess game ever began 1. e4 c5 2. c3 Nc6 3. d4 cxd4 4. cxd4 Nf6 5. Nc3:
Success! Complete central control.
But black can fight back better than this. The biggest downside of 2. c3 is that it takes away the best square for white’s queenside knight, which black can exploit. 2…d5! Is one common response (others are 2…Nf6 and 2…e6).
After 3. exd5 Qxd5, Black’s queen is a lot more secure in the center than it usually is this early in the game, as white cannot play Nc3 and kick it away!
The Alapin variation probably doesn’t give white more than equality if black knows how to handle it, but it’s simple to learn and hard to go wrong with.
White tries to accelerate his lead in development even more, by playing d4 immediately with no preparation. White intends to sacrifice a pawn to open up the position.
2…cxd4 3. c3
Of course, white could take back with the queen on move 3, but this doesn’t make much sense. Black will just get to play …Nc6 and kick the queen away while gaining time, and white is just playing an inferior version of the Open Sicilian mentioned above.
This pawn sacrifice is white’s idea behind the second move.
3…dxc3 4. Nxc3
White is down a pawn, but has chances to get a big lead in development. White’s rooks will eventually exert pressure along the semi-open d-and-c files, and meanwhile black will have to be careful how they develop! For example, after 4…Nc6 5. Nf3 d6 6. Bc4 Nf6?!
Black can defend against the Smith-Morra with accurate play, but it’s a tall task. Many strong players decline to accept the “free” pawn, leading to a position more akin to the Alapin variation mentioned above.
White can forgo all three of the ideas above and not play an early d4 at all, keeping the center closed for the time being.
One such idea is known as the Grand Prix Attack – 1. e4 c5 2. Nc3 Nc6 3. f4
As with many closed Sicilian lines, the Grand Prix Attack can be better understood conceptually than by delving into variations, as both sides have plenty of options to continue with. Rather than opening the center up right away, white builds up on the kingside.
Black is likely to do the same on the queenside. Both sides reserve the right to strike in the center at a later point if it becomes advantageous to do so!
3…g6 4. Nf3 Bg7 5. Bc4 e6 6. 0-0 d6 7. d3 Nge7 8. Qe1 a6 9. f5 b5
This is Hrair – Ivanov, Russia 2006, and is a good illustration of how play can proceed! Both sides have an advantage on their respective wings, though white emerged victorious in this particular game.
The Sicilian Defense is a strategically rich, highly complex opening. Many players who play the King’s Pawn Opening as White find this daunting, but there’s a variation for everyone! Whether you prefer the highly ambitious Open Sicilian, the simple and sound Alapin, the sacrificial Smith-Morra Gambit, or the slow build-up of the Closed Sicilian, learn it well, and you can stop fearing the dangerous Sicilian Defense!
