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

Before the first move

The Richter-Rauzer is one of the most aggressive ways for White to meet the Classical Sicilian. By pinning the knight on f6 and castling queenside, White signals an all-out attack on your king. You must respond with precise development and counter-punches on the queenside to maintain the balance in this high-stakes battle.

1. e4White

White opens with e4, the most common move at all levels. It immediately fights for the d5 and f5 squares while preparing to develop the kingside. Black has many responses, including the solid e5, the French Defense with e6, or the sharp Sicilian Defense with c5.

1... c5Black · your move

Move your pawn to c5. By playing the Sicilian Defense, you create an asymmetrical position and fight for the d4-square. You are telling White that you aren't looking for a draw but want a complex struggle where your extra central pawn will eventually provide long-term advantages.

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

2. Nf3White

White plays Nf3, the main move in the Sicilian. It prepares the d4 push and develops a piece toward the center. White could also try the Bowdler Attack with Bc4 or the Keres Variation with Ne2, but Nf3 remains the gold standard for challenging Black's setup.

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

2... Nc6Black · your move

Bring your knight to c6. This develops a piece toward the center and increases your control over the d4 and e5 squares. This is the Classical Sicilian approach, where you focus on piece pressure before deciding on your central pawn structure.

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, challenging the c5 pawn immediately. This is the defining move of the Open Sicilian. White could also choose the Rossolimo Attack with Bb5, which avoids the main lines and leads to more positional maneuvering, but d4 is the most ambitious try.

Other paths here: Bb5 (Sicilian Defense: Nyezhmetdinov-Rossolimo Attack) · b4 (Sicilian Defense: Portsmouth Gambit) · b3 (Sicilian: 2...Nc6 3.b3) · Bc4 (Sicilian: 2...Nc6 3.Bc4)

3... cxd4Black · your move

Capture the pawn on d4. This trade is essential to your strategy. You exchange your flank pawn for White's central d-pawn, which gives you a central pawn majority and an open c-file for your future queenside counterplay.

Other paths here: e6 (Sicilian Defense: Franco-Sicilian Variation)

4. Nxd4White

White recaptures with Nxd4, placing the knight on a dominant central square. White now has a space advantage and faster development, but Black has the long-term asset of an extra central pawn. This balance of power is the heart of Sicilian theory.

4... Nf6Black · your move

Develop your knight to f6. This move attacks the e4 pawn and forces White to defend it, usually with the knight from b1. It is a vital developing move that prepares for kingside castling and maintains pressure on the center.

Other paths here: g6 (Sicilian Defense: Accelerated Dragon) · Qc7 (Sicilian Defense: Flohr Variation) · Qb6 (Sicilian Defense: Godiva Variation) · e5 (Sicilian Defense: Löwenthal Variation)

5. Nc3White

White plays Nc3, defending the e4 pawn and developing another piece. This is the most solid and common response. White is now ready to meet various Black setups with aggressive intent, particularly the Classical and Scheveningen variations.

5... d6Black · your move

Move your pawn to d6. This solidifies your control over the e5 square and opens a path for your light-squared bishop. You are entering the Classical Sicilian proper, preparing a flexible defense against White's upcoming kingside pressure.

Other paths here: e5 (Sicilian Defense: Lasker-Pelikan Variation) · Qb6 (Sicilian: Open, 2...Nc6, 5...Qb6) · e6 (Sicilian - Four Knights Variation)

6. Bg5White

White plays Bg5, the Richter-Rauzer. This is a very sharp weapon designed to disrupt Black's kingside. White could also play the Sozin with Bc4 or the Classical Be2, but Bg5 is the most direct way to challenge Black's setup.

Other paths here: Nde2 (Sicilian Defense: Spielmann Variation) · Bd3 (Sicilian Defense: Yates Variation) · Bc4 (Sicilian Defense: Sozin, not Scheveningen) · Be2 (Sicilian Defense, classical)

6... e6Black · your move

Push your pawn to e6. This move blunts the pressure from White's knight on d4 and prepares to develop your dark-squared bishop. It is the most resilient way to handle the pin on f6, creating a solid wall in the center.

Other paths here: g6 (Sicilian Defense: Richter-Rauzer Variation, Dragon Variation) · Bd7 (Sicilian Defense: Richter-Rauzer Variation, Modern Variation)

7. Qd2White

White plays Qd2, continuing the plan of queenside castling. This is the most aggressive setup. White could also try the Podebrady Variation with Nb3, but Qd2 is the standard way to prepare the long castle and the subsequent pawn storm.

Other paths here: Nb3 (Sicilian Defense: Richter-Rauzer Variation, Podebrady Variation)

7... a6Black · your move

Move your pawn to a6. This is a prophylactic move that prevents White's pieces from using the b5 square and prepares your own queenside expansion with b5. In the Richter-Rauzer, this timing is critical for your counter-attacking plans.

Other paths here: Be7 (Sicilian Defense: Richter-Rauzer Variation, Classical Variation)

8. O-O-OWhite

White castles queenside, signaling the start of the real battle. The king is safe for now, and the rooks are connected. White's plan is clear: use the kingside pawns to rip open Black's position before Black can generate counterplay.

8... Bd7Black · your move

Develop your bishop to d7. This completes your minor piece development on the queenside and prepares to bring your rook to c8. You are keeping your king in the center for a moment to see how White commits their forces.

9. f4White

White plays f4, an aggressive move that prepares a central or kingside breakthrough. White is looking to capitalize on their lead in development. You must stay alert, as White is ready to push e5 or f5 to disrupt your coordination.

9... Be7Black · your move

Develop your bishop to e7. This finally prepares you to castle kingside if necessary and breaks the pin on your knight. You have completed your development and are ready to meet White's aggression with energetic counterplay on the c-file.

Where you stand

The stage is set for a classic Sicilian slugfest. White will aim to use the f-pawn and e-pawn to crash through the center or kingside, while Black will use the open c-file and queenside pawn advances to target the White king. Precision is required for both sides: one slow move can lead to a decisive disadvantage in these sharp, opposite-side castling positions.

• c6-a5 Knight maneuvers to pressure the queenside
• f4-f5 White pushes f5 to open the kingside
• a8-c8 Rook moves to the open c-file
• g5-f6 White trades bishop for knight to weaken pawns
• b7-b5 Black starts the queenside pawn storm
