Sicilian Defense: Open Classical Richter-Rauzer
Sicilian Defense
Definition
The Sicilian Defense is the opening that begins with the moves 1. e4 c5. Black immediately contests the d4–square and creates an asymmetrical pawn structure, leading to rich, double-edged play. It is the most popular reply to 1. e4 at every level of competition.
Typical Move Order
1. e4 c5 is mandatory. From there, the game may branch into:
- Open lines after 2. Nf3 d6 (or 2…Nc6/2…e6) 3. d4 cxd4 4. Nxd4.
- Closed systems such as 2. Nc3 or 2. Nf3 Nc6 3. g3.
- Anti-Sicilians like the Alapin (2. c3) or Rossolimo (2. Nf3 Nc6 3. Bb5).
Strategic Significance
- Creates an immediate imbalance: White has a central pawn majority; Black gains a semi-open c-file for counterplay.
- Often leads to sharp, tactical middlegames in the Open Sicilian, or maneuvering setups in the Closed or Anti-Sicilians.
- Favored by world champions including Fischer, Kasparov, Anand, and Carlsen.

Interesting Facts
- The first modern exposition of the Sicilian was by Italian priest Pietro Carrera in 1617, but its tournament popularity exploded only in the 20th century.
- Statistically, the Sicilian yields the highest winning percentage for Black among major replies to 1. e4.
- Kasparov vs Deep Blue, 1997 featured a Sicilian Najdorf in Game 1, underlining its top-level relevance even in man-versus-machine battles.
Open Sicilian
Definition
An “Open Sicilian” arises after the sequence 1. e4 c5 2. Nf3 d6/…Nc6/…e6 3. d4 cxd4 4. Nxd4. By exchanging the d-pawn for Black’s c-pawn, White opens the center and gains quick piece activity.
Key Characteristics
- Semi-open files: White obtains a half-open d-file; Black, the half-open c-file.
- Lead in development vs. structural dynamism: White tries to exploit faster piece play, while Black aims for counter-attacks against the king side or center.
- Branching variations: Najdorf, Dragon, Scheveningen, Classical, Sveshnikov, Kalashnikov, and more.
Typical Continuation
Historical Significance
The Open Sicilian became mainstream after World War II, popularized by masters such as Miguel Najdorf and later by Bobby Fischer, who famously wrote, “The Open Sicilian is White’s best try for a win.”
Famous Game
Fischer – Tal, Bled 1961 featured a breathtaking Open Sicilian (Najdorf) where Tal sacrificed the exchange on c3, showing the razor-sharp themes typical of the variation.
Classical Sicilian
Definition
The Classical Sicilian is an Open Sicilian line reached after:
Black develops both knights before committing the kingside bishop, keeping flexible options such as …e6, …g6, or …e5.
Main Ideas for Black
- Control of the central dark squares (d4, e5).
- Pressure along the half-open c-file, often doubling rooks on c8/c7.
- Pawn breaks …d5 or …e5, depending on White’s setup.
Main Ideas for White
- Rapid development and potential kingside attacks (e.g., Richter-Rauzer).
- Queenside expansion with a4, a5 in calmer lines.
Notable Practitioners
Used by Garry Kasparov in his early career, Anatoly Karpov (as Black in his youth), and more recently by Fabiano Caruana.
Classic Encounter
Kasparov – Karpov, Linares 1993: Kasparov unleashed a ferocious Richter-Rauzer as White, demonstrating both the promise and the dangers inherent in the Classical Sicilian.
Richter-Rauzer Attack
Definition
The Richter-Rauzer Attack is White’s most aggressive system against the Classical Sicilian, starting:
Named after German master Kurt Richter and Soviet theoretician Vsevolod Rauzer, it pins the f6-knight, targeting the d5-square and preparing a rapid kingside offensive.
Typical Plans
- White plays Qd2, 0-0-0, f3, g4, h4 to launch a pawn storm at Black’s king.
- Black counters with …e6, …a6, …Bd7, and often …g6 or the modern …h6 & …g5 “Poisoned Pawn” style.
- Center break …d5 is Black’s dream equalizer; preventing it is a thematic goal for White.
Famous Game
Polugaevsky – Tal, Soviet Ch. 1969 showcased Tal’s daring exchange sacrifice …Rxc3!!!, a benchmark example of Black’s counterplay in the Richter-Rauzer.
Interesting Tidbits
- The once-feared “Poisoned Pawn Variation” (…Qb6 snatching the b2-pawn) stems from this attack and influenced opening theory for decades.
- Modern engine analysis still finds fresh resources for both sides, keeping the variation theoretically vibrant.
Nezhmetdinov-Rossolimo Attack
Definition
Often shortened to the “Nezhmetdinov Attack,” this Anti-Sicilian system arises after:
It is jointly named for Soviet tactician Rashid Nezhmetdinov and Russian-American GM Nicolas Rossolimo. White eschews d4, instead pinning the c6-knight to inflict structural damage or seize quick positional pressure.
Strategic Themes
- Doubled c-pawns: After Bxc6 dxc6, Black’s pawn structure is compromised but gains the bishop pair.
- Piece activity: White’s light-square bishop may reroute (Ba4, Bb3) to keep tension.
- Flexible center: White can later choose c3 & d4, or play for a quick d3, 0-0, Re1, c3 setup.
Main Black Responses
- 3…g6 entering a fianchetto structure.
- 3…e6 preparing …Nge7 and …d5.
- 3…d6 maintaining a solid “Sveshnikov-style” center.
Historical & Practical Significance
Rossolimo employed the line with great success in mid-20th-century tournaments, while Nezhmetdinov’s spectacular attacking games (many ending in brilliant combinations) popularized its tactical potential. In the 21st century, Magnus Carlsen, Levon Aronian, and Wesley So routinely wheel it out to sidestep theoretical minefields of the Open Sicilian.
Memorable Encounter
Carlsen – Giri, Wijk aan Zee 2017: Carlsen used the Nezhmetdinov-Rossolimo to grind a long endgame win, underlining its positional venom.
Fun Fact
Nezhmetdinov’s own masterpiece in the line (vs. Polugaevsky, 1958) featured the queen sacrifice 24.Qxf6!!, a position still cited in tactic manuals.
