Sicilian Defense – 1.e4 c5 (Variations, Move Orders, Purpose)

The Sicilian Defense is characterized by the move order 1.e4 c5.

In this, the player with the black pieces responds to the white’s first move, pawn to e4, with pawn to c5.

The objective is to fight for control of the center of the board right from the start of the game.

It deviates from the traditional 1…e5, thereby opening up a different and complex variety of possibilities.

Strategy and Purpose of the Sicilian Defense

The main strategy of the Sicilian Defense is to undermine white’s control of the center.

The c5 move challenges white’s center dominance, aiming to take control of the d4 square with a pawn.

It also opens up a pathway for black to develop the queen-side knight to c6.

The defense is tactical, encouraging complex and varied positions.

Variations of the Sicilian Defense

The Sicilian Defense is a popular chess opening that arises after the moves 1.e4 c5. It is known for its dynamic and flexible nature, offering both tactical and positional opportunities.

There are numerous variations within the Sicilian Defense, and here are some of the most commonly played ones:

1. Open Sicilian: a. Najdorf Variation b. Scheveningen Variation c. Dragon Variation d. Sveshnikov Variation e. Classical Variation f. Richter-Rauzer Variation g. Kalashnikov Variation h. Sozin Variation
2. Closed Sicilian: a. Grand Prix Attack b. Closed Sicilian with d3 c. Closed Sicilian with Nc3
3. Alapin Variation: This is characterized by 2.Nf3 followed by 3.d4, deviating from the main lines of the Open Sicilian.
4. Smith-Morra Gambit: This is a gambit where White plays 2.d4 and sacrifices a pawn for quick development and attacking chances.
5. Closed Sicilian with g3: This involves playing g3 and Bg2 to set up a solid pawn structure.
6. Closed Sicilian with Nf3 and g3: Similar to the previous variation, but with Nf3 before g3.
7. Closed Sicilian with Nf3 and Bg2: In this variation, White fianchettoes the king’s bishop with Bg2.
8. Closed Sicilian with Nf3, g3, and Bg2: This combines all the elements of the previous three variations.

These are just some of the many variations of the Sicilian Defense, and within each variation, there are further sub-variations and specific move orders.

The choice of which variation to play depends on personal preference, playing style, and familiarity with the positions that arise.

e. Classical Variation: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6

f. Richter-Rauzer Variation: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bg5

g. Kalashnikov Variation: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 e5 5.Nb5 d6

h. Sozin Variation: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.Bc4

The Open Sicilian is one of the most popular and aggressive approaches White can take in response to the Sicilian Defense, which begins with 1.e4 c5.

It is characterized by the moves 2.Nf3 and 3.d4.

The opening begins as follows:

1. e4 c5 (Sicilian Defence)
2. Nf3 (Preparing for d4, challenging Black’s control of the d4 square) d6/Nc6/e6 (These are the three main options for Black. Each sets up a different type of pawn structure and can lead to a different variation of the Sicilian.)
3. d4 (This move initiates the Open Sicilian)

In the Open Sicilian, the game typically becomes highly complex and tactical. After 3…cxd4 4.Nxd4, White establishes a strong presence in the center and gains a lead in development, and has the potential to launch an aggressive attack on the kingside.

One of the key imbalances in this opening is the pawn structure. After the exchange on d4, White is left with a pawn majority on the kingside, while Black has a pawn majority in the center. This pawn majority can become a key strategic asset for Black in the middlegame and endgame, as it can potentially be used to create a passed pawn.

Moreover, the trade on d4 also opens the c-file for Black, which can be used to generate counterplay on the queenside. This counterplay can potentially develop into a full-blown attack, especially if White decides to castle queenside.

Despite the imbalances, the Open Sicilian is known for leading to dynamic and balanced positions where both sides have their chances. For this reason, it is a favorite choice among players who seek complex, tactical battles on the chessboard.

Descriptions of Common Sicilian Defense Variations

Smith-Morra Gambit, 2.d4 cxd4 3.c3 dxc3

This is an aggressive gambit where White sacrifices a pawn in the center to speed up development and open lines.

The Siberian Trap, which starts with 4.Nxc3 Nc6 5.Nf3 e6 6.Bc4 Qc7 7.0-0 Nf6 8.Qe2 Ng4, is a line that Black can use to try and trap White into losing a queen.

Sicilian Smith-Morra Morphy Gambit, 2.d4 cxd4 3.Nf3

This variation prioritizes piece development over immediate pawn recovery.

The idea is to gain more control over the center and prepare for a quick kingside castling.

Sicilian Halasz Gambit, 2.d4 cxd4 3.f4

The Halasz Gambit is another aggressive gambit aimed at seizing control of the center quickly and launching a swift attack, particularly aiming for a strong pawn structure to launch a kingside attack.

B21 Sicilian, Grand Prix Attack, 2.f4

This move aims to control the center quickly and launch a kingside attack, often following up with Nf3 and Bb5.

White aims to challenge Black’s pawn structure and create imbalances early on.

B22 Sicilian, Alapin Variation, 2.c3

This variation aims to control the center by threatening to exchange on d4 and play d4 himself, getting a solid pawn center. It aims to deny Black the typical pawn structures of the Sicilian Defense.

B23 Sicilian, Closed, 2.Nc3

Here, White aims for a slower, strategic game, focusing on piece development and pawn structure rather than immediate confrontation in the center. The Closed Sicilian can lead to complex positional games.

B24 Sicilian, Closed, 2.Nc3 Nc6 3.g3

In this line, White prepares to fianchetto the bishop to g2, aiming for a flexible and solid setup, focusing on control over the center and potential for a kingside attack.

B25 Sicilian, Closed, 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6

This is a standard position for the Closed Sicilian. White’s setup is solid and flexible, allowing for multiple plans including a kingside pawn storm or central expansion with e4-e5.

B26 Sicilian, Closed, 6.Be3

In this line, White is developing the bishop to control the center and discourage d5, while also preparing queenside castling for an aggressive kingside pawn storm.

B27 Sicilian Defense, 2.Nf3

A standard second move for White, aiming to control the center and prepare for d2-d4, to challenge Black’s central pawn on d5 and claim the center.

Katalimov Variation, 2…b6

This is a hypermodern approach where Black immediately fianchettos the bishop to b7, aiming to control the center from a distance.

Black also prepares to develop the knight to f6 without blocking the bishop.

Hungarian Variation, 2…g6

This is another hypermodern approach where Black aims to fianchetto the bishop to g7 and control the center from a distance. This setup often leads to the Dragon variation of the Sicilian if followed by …d6 and …Nf6.

Quinteros Variation, 2…Qc7

This move aims to control the e5-square and prepare for kingside development.

It’s a bit unusual, delaying the development of Black’s minor pieces.

Mongoose Variation, 2…Qa5

This is an offbeat line where Black moves the queen out early to put pressure on White’s e5-pawn and dissuade White from d4.

It can be risky if White knows how to exploit the early queen move.

B28 Sicilian, O’Kelly Variation, 2.Nf3 a6

This move is flexible and can transpose into a number of other lines.

The a6 move prepares to expand with …b5, and can support …d5 in one move if White plays d4.

A common response to 2…a6 is 3. c4 (and the most accurate).

Black will often reply with 3…Nc6, followed by 4. d4, producing the likely exchange 4…cxd4

The Geller Line in the O’Kelly Variation goes:

1. e4 c5 2. Nf3 a6 3. c4 Nc6 4. d4 cxd4 5. Nxd4 e5 

6. Nf5 Nf6 (or d6) is considered the most accurate continuation.

Smother Mate Sicilian Line Within the O’Kelly Variation

Interestingly, there is a “smother mate” scenario if black plays 6…Ne7 to attack the knight.

White mates via 7. Nd6, as there are no escape squares for the king and no way to capture the knight.

B29 Sicilian, Nimzovich–Rubinstein Variation, 2.Nf3 Nf6

Black aims to challenge the e4 pawn directly and prepare for d5 in one move if White plays d4.

B30 Sicilian Defence, 2.Nf3 Nc6

This move is flexible and prepares for a variety of plans, including the Classical Sicilian with …d6 and …Nf6, or the Accelerated Dragon with …g7 and …Bg7.

Sicilian, Rossolimo Variation, 3.Bb5

White is looking to simplify the position and damage Black’s pawn structure through a bishop-knight exchange.

This tends to lead to more strategic, less tactical battles.

B31 Sicilian, Nimzovich–Rossolimo Attack, 3.Bb5 g6

Black prepares to fianchetto the bishop, challenging the bishop on b5 and preparing to castle kingside.

B32 Sicilian Defence, 2.Nf3 Nc6 3.d4

White is aiming to gain central space and exchange in the center to open up lines for piece development.

B33 Sicilian, Sveshnikov (Lasker–Pelikan) Variation, 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6

Black provokes e4-e5 to kick the knight and then plays …d6, aiming to create counterplay against the advanced e5 pawn and the d4 knight.

B34 Sicilian, Accelerated Fianchetto, Exchange Variation, 2.Nf3 Nc6 3 d4.cxd4 4.Nxd4 g6

Black aims for a hypermodern setup with a quick fianchetto of the bishop.

The Accelerated Fianchetto looks to exploit the absence of the pawn on d6, which allows Black to push d7-d5 in one move under favorable circumstances.

B35 Sicilian, Accelerated Fianchetto, Modern Variation with 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4

In this line, White develops the bishop to a strong square and prepares to castle kingside.

This setup can lead to a range of sharp, tactical positions.

B36 Sicilian, Accelerated Fianchetto, Maroczy bind 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.c4

The Maroczy bind structure seeks to restrict Black’s pawn breaks and limit Black’s counterplay by controlling the key d5 square.

White aims for a strategic clamp on the position.

B37 Sicilian, Accelerated Fianchetto, Maroczy bind, 5…Bg7

This move continues with the plan of a quick fianchetto, looking to contest the long diagonal and create pressure on White’s center.

B38 Sicilian, Accelerated Fianchetto, Maroczy bind, 5…Bg7 6.Be3

Here, White continues developing and aiming to control key squares in the center and the d-file.

The Be3 also indirectly guards against the d5 pawn break from Black.

B39 Sicilian, Accelerated Fianchetto, Breyer Variation, 5…Bg7 6.Be3 Nf6 7.Nc3 Ng4

In this line, Black aims for early piece activity, provoking White and aiming to disturb the harmony of White’s position.

The Ng4 move attacks the Be3 and the e5 square, creating complications.

B40 Sicilian Defence, 2.Nf3 e6

This is a flexible move for Black, allowing for a variety of setups including the Scheveningen and Paulsen/Taimanov Sicilian.

The e6 move prepares to develop the dark-squared bishop and also controls the d5 and f5 squares.

B41 Sicilian, Kan Variation, 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6

The Kan variation is a flexible and solid setup for Black. The pawn on a6 controls the b5 square and allows the expansion of b5 and Bb7, often leading to a Hedgehog-like setup.

B42 Sicilian, Kan, 5.Bd3

In this line, White develops the bishop to a strong square to defend the pawn on e4 and prepare to castle kingside. This setup also indirectly discourages Black’s …d5 pawn break.

B43 Sicilian, Kan, 5.Nc3

This move continues with natural development, defending the e4 pawn and preparing for a potential pawn advance to e5.

B44 Sicilian Defence, 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6

This is the beginning of the Paulsen/Taimanov setup, which is flexible and can transpose to several different lines based on Black’s responses.

B44 Sicilian, Szén Variation (5.Nb5)

In this line, White’s knight move pressures the d6 square and aims to disrupt Black’s plans. It is a tricky line that can lead to imbalanced positions.

B45 Sicilian, Taimanov Variation, 5.Nc3

The Taimanov Variation features a quick …Nc6 by Black and is characterized by flexibility and robustness. White’s 5.Nc3 aims to control the center and support potential central pawn pushes.

B46 Sicilian, Taimanov Variation

This line continues with the Taimanov setup, with Black potentially aiming to play …d6 and …Nf6 to further control the center and prepare for castling.

B47 Sicilian, Taimanov (Bastrikov) variation

This variation includes …Qc7 by Black, creating a flexible setup that allows Black to respond appropriately to White’s actions. It involves a lot of tactical nuances.

B48 Sicilian, Taimanov Variation

This variation continues the themes of the Taimanov setup, usually with Black playing moves like …Be7, …0-0, and …d6, while looking for opportunities to strike at the white center.

B49 Sicilian, Taimanov Variation

This is another continuation of the Taimanov setup, featuring early piece development and a compact structure for Black.

B50 Sicilian Defense

This move refers to a group of lines that begins with 1.e4 c5 2.Nf3 but where Black does not play 2…d6, 2…e6 or 2…Nc6.

It represents a flexible choice for Black, preparing to respond appropriately to White’s setup.

B51 Sicilian, Canal–Sokolsky Attack

The Canal-Sokolsky (or Rossolimo) attack starts with 3.Bb5+.

This variation is a more positional approach for White, looking to disrupt Black’s pawn structure early.

B52 Sicilian, Canal–Sokolsky Attack, 3…Bd7

Here Black responds to the check with …Bd7, intending to recapture with the queen if White chooses to exchange.

B53 Sicilian, Chekhover Variation

This line features an early …e6 and …d6 by Black, with a subsequent …Qxd5.

This leads to a more symmetric pawn structure in the center, which can give Black solid, but somewhat passive, development.

B54 Sicilian

This is a broad category of Sicilian Defence lines where White plays 2.Nf3 and 3.d4 but Black does not respond with …d6 or …Nc6 at an early stage.

The setup can be flexible and tactical for both sides.

B55 Sicilian, Prins Variation, Venice Attack

The Venice Attack involves an early Qd2 and long-side castling by White, which can lead to sharp, tactical battles as White often launches a pawn storm on the kingside.

B56 Sicilian

Again, this is a broad category, characterized by early …d6 and …Nf6 moves by Black.

This setup prepares …a6, which is often a precursor to a Scheveningen or Najdorf setup.

B57 Sicilian, Sozin (not Scheveningen) including Magnus Smith Trap

This is a sharp line where White develops the bishop to c4 to target the vulnerable f7 square.

The Magnus Smith Trap occurs if Black carelessly moves the knight away from d7 allowing a deadly Qxd8#.

B58 Sicilian, Classical

The Classical Variation is where Black develops the knight to f6 without playing …a6.

This leads to a more traditional setup and fights for central control.

B59 Sicilian, Boleslavsky Variation, 7.Nb3

Here, White’s knight retreats to b3 to free the d4 square for a pawn or another piece.

This unusual move can disrupt Black’s plans and lead to unique positions.

B60 Sicilian, Richter-Rauzer

This line begins with an early Bg5 by White, aiming to double Black’s pawns on the f-file if Black plays …Be7.

This can lead to highly complex positions with chances for both sides.

The modern line of the Richter-Rauzer Variation goes:

1. e4 c5 2. Nf3 Nc6 3. Nc3 d6 4. d4 cxd4 5. Nxd4 Nf6 6. Bg5 Bd7 (Other move orders also possible)

White will generally continue with Qd2 to set up queenside castling within the next few moves.

B61 Sicilian, Richter–Rauzer, Larsen Variation, 7.Qd2

This move prepares long-side castling and connects the rooks. The queen also supports the bishop on g5 and the advance of the kingside pawns.

B62 Sicilian, Richter–Rauzer, 6…e6

Black chooses a solid setup that helps support the center, prepare the development of the dark square bishop, and also enable short-side castling.

B63 Sicilian, Richter–Rauzer, Rauzer Attack

This variation is known for aggressive pawn advances and piece play from White to try to crack open the position while Black’s king is still in the center.

B64 Sicilian, Richter–Rauzer, Rauzer Attack, 7…Be7 defence, 9.f4

White plays f4 to support the center and prepare for an attack on the kingside.

The move also prepares for the possibility of e5, driving away the knight on f6.

B65 Sicilian, Richter–Rauzer, Rauzer Attack, 7…Be7 defence, 9…Nxd4

Black captures on d4 to exchange a pair of knights, aiming to reduce White’s attacking potential.

B66 Sicilian, Richter–Rauzer, Rauzer Attack, 7…a6

The move …a6 prepares for a possible …b5 advance, which can disrupt White’s position and gain space on the queenside.

B67 Sicilian, Richter–Rauzer, Rauzer Attack, 7…a6 defence, 8…Bd7

Black develops the bishop to a safe and effective square. It supports the pawn advance …b5 and also prepares for …Qa5, connecting the rooks.

B68 Sicilian, Richter–Rauzer, Rauzer Attack, 7…a6 defence, 9…Be7

Black completes development and prepares to castle.

The bishop on e7 helps protect the kingside and potentially support a …d5 pawn break in the center.

B69 Sicilian, Richter–Rauzer, Rauzer Attack, 7…a6 defence, 11.Bxf6

By taking on f6, White doubles Black’s pawns and damages the pawn structure.

This gives White potential targets to attack later in the game.

B70 Sicilian, Dragon Variation

The Dragon Variation is characterized by the moves 2.Nf3 and 3.d4 from White and 2…d6 and 3…g6 from Black.

The Dragon Variation is one of the sharpest lines of the Sicilian Defense.

It gets its name because the pawns on d6, e7, f7, g6, and h7 resemble a dragon.

Black fianchettoes the bishop to put pressure on the center and prepares to castle kingside.

B71 Sicilian, Dragon, Levenfish Attack

The Levenfish Attack begins with 6.f4.

This variation aims to challenge Black’s setup immediately, striking at the center and preparing for a rapid deployment of forces, often resulting in a kingside attack.

B72 Sicilian, Dragon, 6.Be3

With 6.Be3, White develops the bishop to control the important d4-square and prepares for a queenside pawn storm after long castling.

B73 Sicilian, Dragon, Classical, 8.0-0

In the Classical Variation, White chooses to castle kingside, opting for a slower, more positional battle.

The fight is often centered around control of the d5 square.

B74 Sicilian, Dragon, Classical, 9.Nb3

Here, White retreats the knight to b3 to reinforce control over the d4 square and remove the knight from possible attacks.

B75 Sicilian, Dragon, Yugoslav Attack

The Yugoslav Attack is a highly aggressive system that involves castling queenside and launching a pawn storm against Black’s kingside.

B76 Sicilian, Dragon, Yugoslav Attack, 7…0-0

Black castles into the attack but trusts the solidity of the pawn structure to withstand White’s assault.

B77 Sicilian, Dragon, Yugoslav Attack, 9.Bc4

In this line, White’s bishop move aims to exert pressure on the f7 square, creating tactical opportunities.

B78 Sicilian, Dragon, Yugoslav Attack, 10.0-0-0

White castles queenside, aiming to begin an aggressive pawn storm on the kingside with moves like h4 and g4.

B79 Sicilian, Dragon, Yugoslav Attack, 12.h4

White starts the pawn storm against Black’s kingside with the idea of opening the h-file for a potential attack on Black’s king.

B80 Sicilian, Scheveningen Variation

Characterized by the setup 2…d6 and 2…e6 from Black, the Scheveningen variation aims for flexibility and control over the central squares.

Black plans to strike in the center with …d5 when appropriate.

B80 Sicilian, Scheveningen, English Attack

The English Attack usually involves f3, Be3, Qd2, and a kingside pawn storm with g4.

White aims to launch a direct attack against the Black king, which often leads to sharp, tactical battles.

B81 Sicilian, Scheveningen, Keres Attack

The Keres Attack (6.g4) is an aggressive attempt to destabilize Black’s pawn structure.

The idea is to control the f5 square and limit the mobility of Black’s pieces.

B82 Sicilian, Scheveningen, 6.f4

White immediately challenges Black’s control of the e5 square and begins preparations for a kingside attack.

B83 Sicilian, Scheveningen, 6.Be2

A quieter approach than the English Attack or the Keres Attack, emphasizing piece development and control of the center.

B84 Sicilian, Scheveningen (Paulsen), Classical Variation

Also a more classical and less aggressive setup, focusing on piece development, center control, and flexibility.

B85 Sicilian, Scheveningen, Classical Variation with …Qc7 and …Nc6

Black plays …Qc7 to support an e5 break and …Nc6 to add more pressure on the d4 square.

Sicilian, Scheveningen, Classical, Vītoliņš Variation

While not possessing an ECO code, the Vītoliņš Variation is characterized by the moves:

1. e4 c5 2. Nf6 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Bb5+ Bd7

B86 Sicilian, Sozin Attack

The Sozin Attack (6.Bc4) aims for a more direct kingside attack, attempting to exploit the sensitive diagonal pointing towards Black’s king.

B87 Sicilian, Sozin with …a6 and …b5

Black plays …a6 and …b5 to gain space on the queenside, and prepare for a possible d5 break.

B88 Sicilian, Sozin, Leonhardt Variation

White plays 7.Be3 to support the knight on d4 and prepare Qd2, castling queenside, and launching a kingside pawn storm.

B89 Sicilian, Sozin, 7.Be3

Similar to the Leonhardt Variation, White develops the bishop to e3 to bolster the knight on d4 and prepare for a queenside castle.

B90 Sicilian, Najdorf

The Najdorf Variation is one of the most popular lines of the Sicilian Defense and is characterized by the moves 2…d6 and 5…a6.

It provides Black with a flexible and robust setup, allowing for both active piece play and pawn storms.

B91 Sicilian, Najdorf, Zagreb (Fianchetto) Variation (6.g3)

The fianchetto variation aims for a solid setup, preparing to castle kingside and giving additional control over the center. The g3 move prepares to fianchetto the bishop, reinforcing control of the center and adding pressure on Black’s d6 pawn.

B92 Sicilian, Najdorf, Opocensky Variation (6.Be2)

The Opocensky Variation focuses on development and kingside safety. The bishop on e2 helps support a future f3 and g4 advance.

B93 Sicilian, Najdorf, 6.f4

The immediate 6.f4 move is a less common move in the Najdorf. White looks to expand on the kingside, potentially paving the way for a pawn storm.

B94 Sicilian, Najdorf, 6.Bg5

The 6.Bg5 move aims to provoke weaknesses in Black’s pawn structure. If Black plays 6…e6, White can play 7.f4 with a strong central structure.

B95 Sicilian, Najdorf, 6…e6

The 6…e6 move provides solid support for d5 and opens lines for the dark square bishop. It is one of the key moves in the Scheveningen setup, often used in conjunction with Najdorf’s …a6.

B96 Sicilian, Najdorf, 7.f4

This is a continuation of the aggressive setup where White looks to quickly advance the pawn to f5 or support e5.

B97 Sicilian, Najdorf, 7…Qb6 including Poisoned Pawn Variation

The Poisoned Pawn Variation arises after 8.Qd2 Qxb2. This is a very sharp line, with Black grabbing a pawn at the cost of lagging development and a potentially exposed queen.

B98 Sicilian, Najdorf, 7…Be7

The 7…Be7 move aims for a more positional game, developing a piece and preparing to castle kingside.

B99 Sicilian, Najdorf, 7…Be7 Main line

This often leads to highly complex positions, with opposite-side castling and attacking chances for both sides.

---

Each of these variations has its own unique plans and ideas.

These descriptions provide a high-level overview of the general plans and ideas in these variations.

However, chess is a highly complex game, and the best move in a given position often depends on the specifics of the position and the opponent’s previous moves.

Other Moves of the Sicilian Defense

Let’s take a look at each of these opening moves following 1.e4 c5 (the Sicilian Defence):

2.Ne2 – The Keres Variation

Named after the great Estonian Grandmaster Paul Keres, this variation offers flexibility.

White may choose to transition to an Open Sicilian with 3.d4, a Closed Sicilian with 3.g3, or continue with 3.Nbc3, delaying the choice between the two.

2.g3

This move has been employed by Mark Taimanov among others. It can transpose into the Closed Sicilian.

An example line is 2…d5 3.exd5 Qxd5, threatening the rook on h1. White can counter with a central buildup via c3 and d4.

2.c4

This is an uncommon move and can lead to positions similar to those in the English Opening.

A recommended response to prevent mainline English theory is 2…Nc6 3.Nc3 e5!, preventing d4.

2.d3

This move indicates White’s intention to develop along King’s Indian Attack lines and often leads to a Closed Sicilian setup.

2.e5

This aggressive move gains space and prevents Black from developing the knight to f6.

It often is followed by 3.f4 or 3.Nf3.

Its downside is that it doesn’t add additional pressure to the center, granting Black several options.

2.Na3

This unorthodox move was brought back to prominence by GM Vadim Zvjaginsev at the 2005 Russian Chess Championship Superfinal.

2.Qh5 – The Wayward Queen Attack

This dubious move threatens Black’s c-pawn.

After 2…Nf6, Black achieves a comfortable position.

2.a3 – The Mengarini Variation

This move aims to play 3.b4 on the next move, setting up a potential Wing Gambit.

2.b3

Followed by 3.Bb2, this is the Snyder Variation.

It has been occasionally used by Nigel Short and is a favorite of Georgian GM Tamaz Gelashvili.

2.Bc4 – The Bowdler Attack

Popular among club players or beginners, this move targets the weak f7 pawn or prepares for quick kingside castling.

It’s easily countered by Black, often leading to a comfortable position.

2.b4 – The Wing Gambit

This risky move sacrifices a pawn to try to dominate the center with an early d4.

It’s rarely seen in grandmaster play due to its dubiousness.

Sicilian Defense: Open, Godiva Variation

Kan Variation or Keres Variation of the Sicilian?

When going with the line:

1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 

In a preliminary way, this line might be considered the Keres Variation.

If black goes with 4…a6 (shown below), this is considered the Kan Variation, which is popularly used today.

This keeps the position flexible for black.

• The dark-squared bishop is able to go to various squares.
• It protects against Nb5.
• It can also prepare for a b5 pawn push. Queen-side pawn storms are common for black in the Sicilian.
• It keeps Nc6 available for future moves.

The Modern Kan Variation continues with 5. Bd3.

Other Open Sicilian Lines

Some other Open Sicilian Lines:

Lowenthal Variation

The Lowenthal Variation is a sideline to typical Open Sicilian lines.

It is found via the line:

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 

The move 4…e5 characterizes the Lowenthal.

Normally, black will go Nf6 or d6 for its fourth move.

4… e5 directly attacks the knight.

White will typically move to b5 (best move), which is often followed by a6 from black, which leads to the knight jumping to d6, followed by taking with the bishop and the queen taking the bishop.

Nimzo-American Variation

The Nimzo-American Variation is found via:

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 d5 

Black’s 4th move 4…d5 attacks white’s central control.

White normally responds by taking the pawn, which attacks the knight or by the knight taking c6 knight.

Flohr Variation

The Flohr Variation puts the black queen on c7 for black’s 4th move:

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Qc7 

The Flohr Variation can sometimes be seen in high-level games.

Godiva Variation

The Godiva Variation puts the black queen on b6 for black’s 4th move:

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Qb6 

The Flohr Variation is considered more solid than the Godiva variation.

Accelerated Dragon, Modern Variation

The Sicilian Defense: Open, Accelerated Dragon, Modern Variation is characterized by black’s fourth move of g6:

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6 

White will often respond with c4 or Nc3.

The Accelerated Dragon, Modern Variation is a relatively solid line that opens as +0.50 to +0.60 for white.

Other Closed Sicilian Lines

The closed Sicilian can be reached by various lines.

The discerning move of the closed Sicilian is Nc3 by white.

From there, many variations exist.

For example, in the line:

1. e4 c5 2. Nf3 Nc6 3. Bb5 d6 4. Nc3 e5 

White can go 5. Bc4 or 5. d3

Slow Variation

Slow Variation of the Sicilian Defense:

1. e4 c5 2. Be2 

Evaluation: +0.10

The Slow Variation of the Sicilian Defense is named due to the weak (or slow) development of the light-squared bishop.

Kronberger Variation

Kronberger Variation of the Sicilian Defense:

1. e4 c5 2. Na3 

Evaluation: 0.00

Here white goes to a3 with the knight on its second move.

On later moves it can go to b5 or c4 (potentially c2).

Even though it looks pointless for white, it’s actually about even to start and gets black out of their preparation, as the Kronberger Variation is not well-known to even grandmasters.

Example Game: Sicilian Defense, Myers Attack, McDonell Attack

Below is an example game that starts out in the Sicilian Defense, and use 2. a4 and 3. f4 as its second and third moves, resulting in a win for white.

This game was between Stockfish (playing white) and Komodo (playing black):

Why is the Closed Sicilian considered weaker than the Open Sicilian?

The Sicilian can be broadly categorized into the Open Sicilian (after 2.Nf3 and 3.d4) and the Closed Sicilian (usually after 2.Nc3 followed by 3.g3 or an immediate 2.g3).

Here’s why the Closed Sicilian is often considered less challenging than the Open Sicilian:

Pawn Structure and Central Control

In the Open Sicilian, White immediately challenges Black’s central d7-d6 pawn by playing d2-d4.

This leads to asymmetrical pawn structures, which often result in dynamic imbalances and chances for both sides.

In the Closed Sicilian, White refrains from an early d2-d4, leading to a more locked pawn structure, which is generally less aggressive.

Piece Activity

The Open Sicilian usually leads to faster piece development and greater central control for White.

This can translate to more immediate threats and tactical opportunities.

The Closed Sicilian often results in slower, flank-based play, with both sides preparing their plans before any direct clash.

Historical Results

Historically, top-level players have achieved better results with the Open Sicilian compared to the Closed variant.

This naturally impacts its reputation.

Complexity and Theory

The Open Sicilian branches out into a vast number of complex lines, each with its own theory.

Preparing against it can be daunting for Black, given the multitude of options available to White.

On the other hand, the Closed Sicilian is less theoretically demanding, and many players feel it allows Black to equalize more easily.

Nature of Play

The Closed Sicilian often results in more strategic, slower-paced games where understanding typical plans and maneuvers is crucial.

While this can catch some players off guard, those who are well-prepared for these slower battles can often navigate the middlegame without much difficulty.

Weaker Is Relative

It’s essential to understand that “weaker” is relative.

At club and amateur levels, the distinction between Open and Closed Sicilian in terms of their objective strength may be negligible.

It’s more about the style of play and individual player preference.

Some players thrive in the slower, maneuvering battles of the Closed Sicilian, while others prefer the sharp, tactical nature of the Open Sicilian.

The Open Sicilian can also transition to the Closed Sicilian depending on the timing of the move Nc3 for white.

Evaluation of the Sicilian Defense

The Sicilian Defense is generally evaluated at around +0.30 to +0.50 for white.

History of the Sicilian Defense

The Sicilian Defense is one of the oldest chess openings, tracing its roots back to the 16th century.

It owes its name to the Italian priest Pietro Carrera, who was from Sicily.

However, it wasn’t until the 20th century that the opening gained mainstream popularity.

This was due to several World Champions, such as Bobby Fischer and Garry Kasparov, frequently employing the defense, demonstrating its effectiveness at the highest level of play.

Is the Sicilian Defense Good for Beginners or Intermediates?

While the Sicilian Defense is considered one of the most aggressive and dynamic responses to 1.e4, its vast range of variations and complex positions can be challenging for beginners.

The tactical nature of the game might be overwhelming for new players, requiring a deeper understanding of chess strategy to navigate successfully.

On the other hand, the defense is excellent for intermediate and advanced players seeking to diversify their repertoire and deepen their tactical understanding.

Sicilian Defense Usage at the Grandmaster Level

The Sicilian Defense is a frequent choice at the grandmaster level, known for its counter-attacking potential and dynamic gameplay.

It has been used by many World Chess Champions, including Garry Kasparov, Vishwanathan Anand, and Magnus Carlsen.

Despite its complexity, the opening is favored by many top-level players for its tactical richness and potential for aggressive play.

This makes it a regular feature in high-stakes international chess tournaments.

It’s also not uncommon to see unbalanced positions, such as queen against rooks.

Below is one example:

Sicilian Defense vs. Caro-Kann Defense

Both the Sicilian Defense (1.e4 c5) and the Caro-Kann Defense (1.e4 c6) are popular responses to 1.e4, each with its unique character.

The Sicilian Defense is known for creating asymmetrical positions and providing opportunities for a counterattack.

It directly fights for control over the d4 square and opens the c-file after d4 by white and cxd4 in response.

This often leads to complex and rich positions, making the Sicilian a favorite among players looking for dynamic play and winning chances with black.

The Caro-Kann Defense is more solid and defensive. Black looks to challenge the central e4 pawn with d5, while aiming for a strong, robust pawn structure.

Unlike the Sicilian, which often leads to sharp, tactical battles, the Caro-Kann tends to result in a more positional struggle.

Sicilian Defense (1. e4 c5) vs. 1. e4 e5 (Open Game or Double King’s Pawn Opening)

The Sicilian Defense and the Open Game (1.e4 e5) are two very different responses to 1.e4.

The Open Game tends to lead to symmetrical positions with classical development of pieces and relatively straightforward plans.

Both sides generally develop their pieces to natural squares while fighting for control in the center.

Classical lines such as the Italian Game or the Ruy Lopez evolve from the Open Game.

In contrast, the Sicilian Defense creates asymmetrical positions that lead to rich and complex structures.

The key idea is to allow white to occupy the center with d4, which black immediately challenges with cxd4.

The resulting imbalanced position offers a multitude of strategic and tactical themes, making the Sicilian Defense a preferred choice for players seeking complicated positions and unbalanced play.

Sicilian Defense vs. French Defense

The Sicilian Defense (1.e4 c5) and the French Defense (1.e4 e6) both offer unique methods of countering 1.e4.

In the Sicilian Defense, black looks to create asymmetrical positions that can lead to rich, complex gameplay.

The Sicilian is characterized by a counterattack strategy, where black fights for the d4 square and aims to destabilize white’s center.

The French Defense is a bit more solid and focuses on creating a strong pawn chain to challenge white’s central control.

This often results in a closed position, with play revolving around strategic pawn breaks.

Unlike the Sicilian, where piece play often dominates, the French Defense tends to be more about pawn structure and less about piece activity, especially in the early stage of the game.

Sicilian Defense vs. Modern Defense

The Sicilian Defense (1.e4 c5) and the Modern Defense (1.e4 g6) are both counter-attacking responses to 1.e4, but they approach this objective from different angles.

In the Sicilian Defense, black immediately challenges the center by attacking the d4 square, leading to complex and asymmetrical positions.

The Sicilian is known for its tactical richness and potential for counterplay.

The Modern Defense, however, adopts a hypermodern approach, allowing white to establish a pawn center with d4 and e4.

Black aims to undermine this center later on with moves like …Bg7 and …d6.

This approach can lead to a variety of pawn structures and middlegame plans, with the potential for black to seize the initiative if white overextends.

However, the Modern Defense is generally seen as a riskier choice compared to the Sicilian.

11. What is the Open Sicilian Defense?

Open Sicilian: 2.Nf3 and 3.d4

The Open Sicilian is one of the most aggressive ways to combat the Sicilian Defense.

It begins with the moves 1.e4 c5 2.Nf3 followed by 3.d4 on the next move.

After Black recaptures with 3…cxd4, White usually plays 4.Nxd4, thus opening the game.

The Open Sicilian aims to create asymmetrical pawn structures which lead to imbalanced positions, providing ample opportunities for both sides to play for a win.

Some of the most popular continuations for Black include the:

• Najdorf Variation (5…a6)
• Scheveningen Variation (5…e6)
• Dragon Variation (5…g6)
• Sveshnikov Variation (5…e5)

Each of these lines offers different strategic and tactical ideas.

12. What is the Paulsen Variation of the Sicilian Defense?

Paulsen Variation: 4…a6 5.Nc3 Qc7

The Paulsen Variation, also known as the Kan Variation, is a less tactical and more positional response to the Open Sicilian.

It was developed by the German player Louis Paulsen in the 19th century. It begins with 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6, and after 5.Nc3, Black often plays 5…Qc7.

In this variation, Black aims for a flexible setup where they can develop their pieces quickly without committing to a specific pawn structure too early.

The move 5…Qc7 keeps options open, as it supports an eventual …d5 pawn break, helps prepare …Nf6 (since it adds protection to the e5 square), and prevents any annoying bishop checks on b5.

There are many possible setups for both sides in this variation.

White can choose to develop their light-squared bishop to either d3 or e2 (or even g2 in some cases), while Black has a wide array of setups that can involve …d6 and …Nf6, or …b5 and …Bb7, depending on how the game progresses.

The Paulsen is a flexible and robust system, but it requires a good understanding of Sicilian-type positions and pawn structures.

13. What is the Scheveningen Variation of the Sicilian Defense?

Scheveningen Variation: 5…e6

The Scheveningen Variation is a classic system against the Open Sicilian.

It is named after the Dutch city where an international tournament helped popularize the line in 1905.

It starts with the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6.

The idea behind this system is to create a solid and flexible pawn structure with pawns on d6 and e6, which provides Black with a strong center and the ability to launch various types of counterattacks.

The Scheveningen Variation is known for leading to rich middlegame positions where both sides have chances.

The line became less popular after the introduction of the English Attack (6.Be3, followed by Qd2 and O-O-O) and the Scheveningen Keres Attack (6.g4), which put Black under early pressure.

However, it is still played at all levels and is considered a solid and reliable choice against the Sicilian.

Some of the world’s top players, such as Garry Kasparov and Anatoly Karpov, have used it throughout their careers.

14. What is the Najdorf Variation of the Sicilian Defense?

Najdorf Variation: 5…a6

The Najdorf Variation is one of the most popular lines of the Sicilian Defense and is named after the Argentine Grandmaster Miguel Najdorf.

It begins with the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6.

The main idea behind the Najdorf Variation is flexibility.

The move 5…a6 prepares to expand on the queenside with …b5, prevents any annoying Bb5+ checks, and sometimes prepares for a …e5 push.

This variation often leads to complex and exciting positions and has been played by numerous world champions, including Bobby Fischer and Garry Kasparov, making it a favorite among aggressive players.

In the Najdorf Variation, White has several major options including the English Attack (6.Be3 followed by f3, Qd2, and O-O-O), Scheveningen style setups with Be2 followed by 0-0, and the aggressive 6.Bg5 aiming to provoke weaknesses in Black’s position.

15. What is the fastest checkmate that can be achieved in the Sicilian Defense?

The fastest checkmate from the Sicilian Defense is 4 moves, characterized by the line:

1. e4 c5 2. Nc3 e6 3. Nb5 Ne7 4. Nd6#

Conclusion

The Sicilian Defense, with its numerous variations, complex strategy, and rich history, continues to be a crucial part of the game of chess.

It may not be the easiest opening to learn for beginners, but its depth and versatility make it an invaluable tool for any advanced player’s arsenal.
