Sicilian Nyezhmetdinov-Rossolimo Fianchetto Variation

Sicilian Defense Nyezhmetdinov-Rossolimo Fianchetto Variation

Definition

The Nyezhmetdinov-Rossolimo Fianchetto Variation is a branch of the Sicilian Defense arising after the moves 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6. White combines Rossolimo’s early Bb5 pin with a kingside fianchetto (g2–g3, Bg2) in the spirit of Rashid Nyezhmetdinov, aiming at long-term positional pressure and flexible piece play rather than the heavy, theory-laden main lines of the Open Sicilian. ECO codes usually list it as B31–B32.

Typical Move-Order

The most common sequences reach a position similar to the following:

  1. e4 c5
  2. Nf3 Nc6
  3. Bb5 g6
  4. O-O Bg7
  5. Re1 e5
  6. Bxc6 dxc6
  7. c3 (or d3) …

Other popular alternatives for White on move 4 are 4. Bxc6, 4. c3, and 4. g3, each steering play into slightly different pawn structures while keeping the same strategic DNA.

Strategic Themes

  • Structural Targets: After the thematic exchange Bxc6, Black’s doubled c-pawns (c7-c6 or c6-c5) become permanent long-term weaknesses that White can pressure with Nc3, d4, Qa4, or even b2-b4.
  • Dark-Square Control: By fianchettoing the king’s bishop, White keeps a firm grip on the long diagonal (a1–h8) and especially the central square d5, often restricting Black’s typical Sicilian break …d6–d5.
  • Flexible Center: White’s c- and d-pawns remain mobile. Plans include c2-c3 & d2-d4 (building a Maroczy-like bind) or d2-d3 & a later c2-c3, keeping the structure closed and maneuvering pieces.
  • Piece Activity vs. Bishop Pair: Black willingly accepts the bishop pair in exchange for structural damage. Whether that bishop pair can be activated before the pawn weaknesses are targeted is the key strategic battle.
  • Counterplay for Black: Typical ideas are …e7-e5 (seizing space), …f7-f5 breaks, or a swift …d7-d5 pawn lever once development is complete.

Historical Notes

  • Nicolas Rossolimo (1910-1975) popularised 3. Bb5 against the Sicilian in the 1940s and 1950s, scoring an impressive +70 % with it in master play.
  • Rashid Nyezhmetdinov (1912-1974), a brilliant Soviet tactician, was among the first to combine 3. Bb5 with an early g2-g3, adding a new strategic layer to the line.
  • The variation’s modern theoretical treatment blossomed after its adoption by elite players such as Garry Kasparov, Magnus Carlsen, and Hikaru Nakamura when they needed a sharp yet anti-Sicilian weapon without entering main-line Najdorf theory.

Modern Practice

  • Top-Level Usage: Carlsen–Giri, Tata Steel 2017 saw the line 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6 4. O-O Bg7 5. Re1 e5 6. b4!?, demonstrating the variation’s resilience even against the best-prepared Sicilian experts.
  • Computer Evaluation: Engines typically start around +0.20 to +0.35 for White—enough to claim a nagging edge without risking the sharp tactical minefields of other Sicilians.

Typical Plans at a Glance

  1. Exchange on c6 when convenient to inflict structural damage.
  2. Set up with g2-g3, Bg2, d2-d3 (or d2-d4 later), Re1, Nbd2–c4 or Nc3–e4, and sometimes a2-a4-a5 to gain queenside space.
  3. Target the c-pawn(s) with Rc1–c4, Qa4, or Bf4.
  4. React to Black’s …f5 or …d5 breaks with accurate piece re-routing: Nd2-c4-e3, or exf5 and Be3-d4 to clamp the dark squares.

Interesting Facts & Anecdotes

  • Rossolimo was also a Parisian taxi driver; he reportedly stored a small chess set under his seat and would challenge passengers during traffic jams.
  • Nyezhmetdinov, despite never becoming a grandmaster, held a lifetime plus score against both Mikhail Tal and David Bronstein—testament to the attacking potential that still inspires Rossolimo aficionados today.
  • In correspondence chess, the line with 4. Bxc6 dxc6 5. d3 Bg7 6. h3 has scored an eye-popping 65 % for White, showing that even in deep engine-checked play the structural plus is durable.
