Sicilian Defense: Richter-Rauzer Variation
Sicilian Defense: Richter-Rauzer Variation
Definition
The Richter-Rauzer Variation is a sharp, double-edged line of the Sicilian Defense that begins after
It belongs to the Classical Sicilian (ECO codes B60–B69). The move 6.Bg5 pins Black’s knight on f6, intensifies pressure on the central d5-square, and often provokes structural concessions. The line is named for German tactician Kurt Richter (1900-1969) and Ukrainian theoretician Vsevolod Rauzer (1908-1941), who independently championed it in the 1930s.
Typical Move Orders
- 6…e6 7.Qd2 a6 8.O-O-O Bd7 (Old Main Line)
- 6…e6 7.Qd2 Be7 8.O-O-O O-O (Modern/Neo-Classical)
- 6…e6 7.Qd2 h6 8.Bh4 g5 9.Bg3 (Perenyi Attack)
- 6…e6 7.Qd2 Qb6 (Malinin Variation)
- 6…g6 (Prins system; a hybrid with the Dragon)
Strategic Ideas
- For White
- Pin the f6-knight and, when appropriate, capture on f6 to inflict doubled g-pawns.
- Castle long (O-O-O) and launch a kingside pawn storm with f2-f4-f5 and/or g2-g4.
- Occupy the d5-outpost; a knight on d5 can be crushing once Black’s dark-squared bishop is exchanged.
- For Black
- Counter in the center with …d6-d5 or …e6-e5, breaking the pin and freeing the position.
- Attack the white king on the queenside with …a6, …b5, …Rc8 and pawn storms.
- Choose between keeping the bishop pair or voluntarily doubling pawns to seize the h-file for attack.
Historical Significance
Rauzer’s deep analysis in the 1930s made him a pioneer of dynamic Sicilian play. After World War II the variation became a principal arena for theoretical debate: Botvinnik used it to challenge emerging stars, Fischer scored key wins in his 1971 Candidates run, and Kasparov–Anand battles in the 1990s pushed the theory even further. In the engine era it remains a laboratory for cutting-edge preparation; novelties regularly appear well past move 20.
Illustrative Games
- Bobby Fischer – Mark Taimanov, Candidates, Vancouver 1971: Fischer’s exchange sacrifice on d5 highlighted White’s attacking potential and launched his 6-0 sweep.
- Garry Kasparov – Viswanathan Anand, World Championship (Game 10) 1995: a textbook opposite-side castling slug-fest culminating in a queenside breakthrough for Black that backfired after accurate defence.
- Veselin Topalov – Ruslan Ponomariov, Linares 2003: shows the razor-sharp 7…h6 8.Bh4 g5 branch from the black perspective.
Interesting Facts & Anecdotes
- Vsevolod Rauzer died on the Leningrad front in 1941; many of his analyses were published only posthumously, yet still stand up to modern engine scrutiny.
- Kurt Richter’s flashy 22-move win over Pfaffenroth (Berlin 1935) popularised 6.Bg5 virtually overnight in German chess circles.
- During the 1980s Kasparov’s team prepared so many sub-lines of 6…e6 7.Qd2 a6 that Karpov jokingly called the variation “Kasparov’s jungle”.
- Correspondence players sometimes pre-arrange “drawing trees” 30+ moves deep because databases contain thousands of heavily analysed Richter-Rauzer games.
