Common Lines In the Sicilian Defense

The Sicilian Defense may be the single mostcommon chess openingin modern play. There are countless lines that can arise from the starting moves of 1.e4 c5.

Sicilian Defense: Starting Position

The Sicilian Defense allows Black to attack thed4square and fight for the center without the symmetry that results from 1...e5. This generally leads to unbalanced positions and usually leaves black with a central pawn majority after trading his c-pawn for White's d-pawn. Learn the common lines that arise with this strategy.

Smith-Morra Gambit

The Smith-Morra Gambit (1.e4 c5 2.d4 cxd43.c3)是受欢迎的,至少是在俱乐部水平occasionally by even somemasters. If Black accepts the gambit by taking the pawn onc3, White will play 4.Nxc3, gaining an early initiative and a dangerous attack.

While this gambit may not be entirely sound, it is dangerous in the hands of a player who knows the opening well, especially against an unprepared opponent.

Alapin Variation

The Alapin Variation is reached if White plays 2.c3. While this supports thed4advance, it takes away thec3square, usually a good place for White's queenside knight.

Closed Sicilian

Another alternate second move for White is 2.Nc3, which typically ushers in the Closed Sicilian. This system,popular at all levels, allows White to keep the center closed. Typically, White plans to play 3.g3and attack on the flanks.

Another alternative for White is 3.f4, which is known as the Grand Prix attack

Classical Sicilian

The Classical Sicilian (reached from many move orders, such as 1.e4 c52.Nf3 d63.d4 cxd44.Nxd4 Nf65.Nc3 Nc6) is one of the soundest lines of the Sicilian for Black, if not always the most enterprising. White has several options beginning on the sixth move, such as the Richter-Rauzer attack and the Sozin attack.

Sveshnikov Variation

Popularized byEvgeny Sveshnikovin the 1970s, the Sveshnikov is marked by an earlye5thrust by Black (for instance: 1.e4 c52.Nf3 Nc63.d4 cxd44.Nxd4 Nf65.Nc3 e5). This is one of the riskier Sicilians for Black to play, but also one that gives the second player many chances to play for a win. For that reason, the Sveshnikov Variation is quite popular at the top levels of chess.

Dragon Variation

Named for the formation of pawns fromh7tod6(which were noted to look like the stars in the Draco constellation), the Dragon Variation is one of the sharpest openings in chess.

Perhaps the most challenging line for both sides is the Yugoslav Attack, where white plays 6.Be3 Bg77.f3. Both sides typically launchfierce attacks: White on the kingside, Black on the queenside.

Accelerated Dragon

The Accelerated Dragon allows Black to adopt a Dragon setup without having to fear the Yugoslav Attack. By playing g6 earlier (usually in line 1.e4 c52.Nf3 Nc63.d4 cxd44.Nxd4 g6), Black retains the ability to playd5in just one move (rather than having previously playedd6in the standard Dragon), saving a tempo.

Conversely, this setup allows White to play the Maroczy Bind (5.c4), making this opening a much more positional one than the standard Sicilian Dragon.

If Black really wants to playg6as soon as possible, an even faster way is the Hyper-Accelerated Dragon, where black playsg6on the second move (1.e4 c52.Nf3 g6).

Scheveningen Variation

The Scheveningen (reached by move orders such as 1.e4 c52.Nf3 d63.d4 cxd44.Nxd4 Nf65.Nc3 e6) is a popular and ambitious system that allows Black to have a solid but flexible position that offers plenty of chances for counterplay on the queenside. Conversely, White has an obvious central space advantage and can choose from a variety of plans.

The Scheveningen variation is popular at the highest levels ofchess, due to its complex and creative nature.

Najdorf Variation

The Najdorf Variation (marked by 5. ...a6) is today the most popular line in the Sicilian. Named after大师Miguel Najdorf, this system is designed to exert control overb5and later put pressure on White'se4pawn. It is also a flexible idea, one that can transpose into many other Sicilian systems.
