Sicilian Defense: Richter-Rauzer Variation, Neo-Modern Variation, Early Deviations

Before the first move

The Richter-Rauzer is one of the most aggressive ways for White to meet the Sicilian Defense. By pinning the f6-knight and preparing queenside castling, White signals an all-out attack. Black responds with the Neo-Modern setup, using a6 to control b5 and keep the position flexible for a counterstrike.

1. e4White

White opens with e4, the most direct way to control the center. By occupying the middle of the board, White prepares rapid development. You'll see this move more than any other, leading into diverse systems like the Ruy Lopez or the Sicilian.

1... c5Black · your move

Move your pawn to c5. This is the Sicilian Defense, the most successful response to e4. You are creating an asymmetrical position, fighting for the d4-square without immediately blocking your own pieces.

Other paths here: f6 (Barnes Defense) · g5 (Borg Defense) · h6 (Carr Defense) · f5 (Duras Gambit)

2. Nf3White

White plays Nf3, the main line of the Sicilian. This develops a piece and prepares the Open Sicilian. White could try the Bowdler Attack with Bc4 or the Keres Variation with Ne2, but the knight move is the most principled and common choice.

Other paths here: Qg4 (Sicilian Defense: Amazon Attack) · Bc4 (Sicilian Defense: Bowdler Attack) · Nh3 (Sicilian Defense: Brick Variation) · g4 (Sicilian Defense: Grob Variation)

2... d6Black · your move

Push your pawn to d6. This move controls the e5-square and prepares to develop your light-squared bishop. It is a solid foundation for many Sicilian structures, including the Dragon and the Najdorf.

Other paths here: f5 (Sicilian Defense: Brussels Gambit) · h6 (Sicilian Defense: Bücker Variation) · g6 (Sicilian Defense: Hyperaccelerated Dragon) · e5 (Sicilian Defense: Jalalabad Variation)

3. d4White

White plays d4, initiating the Open Sicilian. This leads to sharp, tactical positions. White can also choose the Delayed Alapin with c3 or the Kopec System with Bd3 to keep the center more closed, but d4 is the most ambitious try.

Other paths here: c3 (Sicilian Defense: Delayed Alapin Variation, with d6) · Bd3 (Sicilian Defense: Kopec System) · b4 (Sicilian Defense: Wing Gambit, Deferred Variation) · b3 (Sicilian: 2.Nf3 d6 3.b3)

3... cxd4Black · your move

Capture the pawn on d4. This trade is essential for Black in the Open Sicilian. You remove White's central pawn and open the c-file for your future rook activity, maintaining the imbalance of the position.

Other paths here: Nf6 (Sicilian Defense: Modern Variations, Anti-Qxd4 Move Order) · Nd7 (Lazy Knight Variation, Sicilian)

4. Nxd4White

White recaptures with Nxd4, placing a strong piece in the center. While the Chekhover Variation with Qxd4 is a tricky alternative, the knight recapture is the backbone of the Open Sicilian, focusing on piece activity over early queen sorties.

Other paths here: c3 (Sicilian Defense: Modern Variations, Tartakower) · Qxd4 (Sicilian Defense: Chekhover Variation)

4... Nf6Black · your move

Develop your knight to f6. This move attacks the e4-pawn and prepares for kingside development. It is the most active square for the knight, forcing White to defend the center immediately.

Other paths here: g6 (Sicilian Defense: Dragon Variation, Accelerated Dragon) · a6 (Sicilian: Open, 2...d6, 4...a6) · e5 (Sicilian: Open, 2...d6, 4...e5)

5. Nc3White

White plays Nc3, defending the center. This is the most solid and standard reply. White could also try the Prins Variation with f3 or the Ginsberg Gambit with Bc4, but Nc3 is the most reliable way to maintain the central balance.

Other paths here: Bc4 (Sicilian Defense: Modern Variations, Ginsberg Gambit) · f3 (Sicilian Defense: Prins Variation) · Bd3 (Sicilian: Open, 2...d6, 4...Nf6 5.Bd3)

5... Nc6Black · your move

Bring your other knight to c6. This move challenges White's central knight on d4 and prepares to fight for the center. This Classical Sicilian setup leads to high-tension games where every piece is working.

Other paths here: Bd7 (Sicilian Defense: Kupreichik Variation) · e5 (Sicilian: Open, 2...d6, 5.Nc3 e5) · Nbd7 (Sicilian: Open, 2...d6, 5.Nc3 Nbd7) · g6 (Sicilian Defense: Dragon Variation)

6. Bg5White

White plays Bg5, the Richter-Rauzer. This aggressive pin is designed to disrupt Black's kingside. White could choose the Sozin with Bc4 or the Fianchetto with g3, but the Rauzer is the most direct attempt to seize the initiative.

Other paths here: g3 (Sicilian Defense: Classical Variation, Fianchetto Variation) · Be3 (Sicilian: Open, 2...d6, 5.Nc3 Nc6 6.Be3) · f3 (Sicilian: Open, 2...d6, 5.Nc3 Nc6 6.f3) · f4 (Sicilian: Open, 2...d6, 5.Nc3 Nc6 6.f4)

6... e6Black · your move

Push your pawn to e6. This move blunts the pin on your knight and prepares to develop your dark-squared bishop. It also reinforces the d5-square, creating a solid wall against White's central pressure.

Other paths here: Bd7 (Sicilian Defense: Richter-Rauzer Variation, Modern Variation) · a6 (Sicilian: Richter-Rauzer, 6...a6) · Qa5 (Sicilian: Richter-Rauzer, 6...Qa5) · Qb6 (Sicilian: Richter-Rauzer, 6...Qb6)

7. Qd2White

White plays Qd2, signaling the intent to castle queenside. This is the main line, though the Exchange Variation with Nxc6 or the Vitolins with Bb5 are sharp alternatives. White is now ready to complete development and start the attack.

Other paths here: Qd3 (Sicilian Defense: Richter-Rauzer Variation) · Nxc6 (Sicilian Defense: Richter-Rauzer Variation, Exchange Variation) · Bb5 (Sicilian Defense: Richter-Rauzer Variation, Vitolins Variation) · Be2 (Sicilian: Richter-Rauzer, 6...e6 7.Be2)

7... a6Black · your move

Move your pawn to a6. This is the Neo-Modern Variation. You are preventing White's pieces from using the b5-square and preparing for a potential b5 pawn push of your own to expand on the queenside.

Other paths here: Be7 (Sicilian Defense: Richter-Rauzer Variation, Classical Variation) · Qb6 (Sicilian Defense: Richter-Rauzer Variation, Ivanov Variation) · h6 (Sicilian: Richter-Rauzer, 7.Qd2 h6) · Nxd4 (Sicilian: Richter-Rauzer, 7.Qd2 Nxd4)

Where you stand

The position is a classic Richter-Rauzer battlefield. White will likely castle queenside and look for a kingside pawn storm with f4 and g4. Black will develop the dark-squared bishop and look for counterplay on the queenside or in the center. Precision is required from both sides as the game often becomes a race between opposite-side attacks.

• e1-c1 Castle queenside to launch kingside attacks
• f2-f4 Push f4 to start the kingside storm
• c8-d7 Develop the bishop to connect rooks
• b7-b5 Expand on the queenside with b5
• f8-e7 Develop the bishop to prepare castling
