Richter–Rauzer Attack
Richter–Rauzer Attack
Definition
The Richter–Rauzer Attack is a sharp and highly theoretical system against the Classical Sicilian. It arises after the moves: 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Bg5. White immediately pins the f6-knight and prepares a rapid build-up with Qd2, long castling (0-0-0), and a kingside pawn storm. The line is named after German master Kurt Richter and Soviet theoretician Vsevolod Rauzer, pioneers of aggressive anti-Sicilian ideas in the 1930s.
How it is used in chess
The Richter–Rauzer is a go-to weapon for players who want a principled fight against the Classical Sicilian. White uses piece pressure (Bg5, Qd2) and often castles long to launch pawns (f4–f5, g4–g5, h4–h5) at the black king. Black usually aims for development with ...e6 and ...Be7, castles short, and counterattacks on the queenside with ...a6, ...b5–b4, and central breaks like ...d5. The result is a dynamic middlegame with opposite-side castling where time and initiative often outweigh material.
Strategic significance
- White’s pressure on the f6-knight reinforces control of the d5-square and can make Black’s ...d5 break difficult to achieve.
- Black’s structural choice after Bxf6 is critical: ...gxf6 yields doubled f-pawns but opens the g-file for counterplay; ...Qxf6 keeps structure but can be slow.
- Opposite-side castling races are common: White storms the kingside; Black hits back on the queenside and center.
- Key squares: d5 (White outpost), e6 (a typical target for tactics), d6 (can become backward), c3 (a soft spot to undermine with ...b4 or even an exchange sacrifice ...Rxc3).
Historical notes
Vsevolod Rauzer championed the plan of Qd2 and 0-0-0, shaping a major branch of Sicilian theory. The system has cycled through waves of popularity, featuring in countless grandmaster battles and ECO codes B60–B69. Its enduring appeal lies in the clarity of plans for both sides combined with immense tactical depth.
Typical plans for White
- Qd2, 0-0-0, f4–f5 and a pawn storm with g4–g5 or h4–h5 to pry open lines against Black’s king.
- Bxf6 at the right moment to damage Black’s kingside structure or to reduce defenders of d5 and e6.
- Piece placement: Bc4 (eyeing e6/f7), Kb1 (safety), Rhf1 (if needed), and knights heading to d5/f5 in attacking setups.
- Central clamp: e4–e5 can gain space, restrict ...d6–d5, and create invasion points on e6/d6.
Typical plans for Black
- Classical development: ...e6, ...Be7, ...0-0, ...Bd7, ...Rc8, then queenside expansion with ...a6 and ...b5–b4 versus White’s king.
- Timely central counterplay: preparing and executing ...d5 to liberate the position and blunt White’s attack.
- King shelter: ...h6 (asking the bishop), ...g5 in some lines to gain space/tempo; choosing between ...Qxf6 and ...gxf6 recaptures after Bxf6.
- Tactical undermining: ...Na5–c4 or ...Ne5 to trade attackers; exchange sacrifice ideas on c3 to rip open files.
Key variations (by idea)
- 6...e6 (Main Classical): 7. Qd2 Be7 8. 0-0-0 0-0 9. f4 with a standard opposite-side race. Black eyes ...a6, ...Bd7, ...Rc8, and ...b5–b4.
- 6...Qb6!? Early queen pressure on d4 and b2; often followed by ...e6 and ...Be7 while keeping White’s queenside honest.
- 6...g6 A Dragon-style setup within the Classical move order, aiming for dark-square control and counterplay on the long diagonal.
- Flexible move-order tricks: ...a6 or ...Bd7 can be inserted to provoke commitments; many lines transpose among Classical/Scheveningen-style structures.
Common tactical themes
- Nxe6 or Bxf6 tactics exploiting the pin on the f6-knight and pressure on e6/f7.
- Ndb5 jumps hitting c7/d6, especially when Black’s queen or dark-squared bishop is misplaced.
- The ...d5 break as a resource: if successful, Black often solves all problems; if parried, White’s attack gains force.
- Exchange sacrifice ...Rxc3 or ...Rxc3+ in queenside battles to open lines against the white king.
Illustrative lines and model positions

In this typical tabiya, White’s pieces aim at e6 and the kingside; Black organizes ...b5–b4 and ...Na5–c4, backed by ...Rfd8 and the thematic ...d5 break.
Early ...Qb6 idea. Black immediately asks questions on b2 and d4, delaying commitments while preparing ...e6 and ...Be7.

Practical tips
- For White: Coordinate your pawn storm with piece pressure—don’t rush g4–g5 until your pieces (Qd2, Rh1–g1 or Rhf1, Bc4) are harmonized.
- For Black: Keep an eye on the ...d5 break; if you can achieve it under good conditions, your position often solves itself and the kingside attack fizzles.
- Both sides: Insert king-safety moves (Kb1 for White; ...Kh8 for Black) before launching pawn storms to reduce tactical shots on open files/diagonals.
Interesting facts
- Rauzer’s advocacy of Qd2 and long castling was ahead of its time, prefiguring modern engines’ approval of dynamic opposite-side races.
- Many Classical Sicilian players choose repertoire lines specifically tailored to the Richter–Rauzer because it is such a direct test of Black’s setup.
- ECO codes B60–B69 are devoted to this attack, reflecting the breadth of its theory.
