Indian Game and Black Knights Tango

Indian Game

Definition

The term Indian Game (or more commonly “Indian Defence”) describes any opening that begins with the moves 1. d4 Nf6. Black immediately attacks the e4-square with a knight while delaying the classical pawn reply …d5. In modern opening taxonomy, ECO codes A45–A49 and E00–E99 all stem from this root position.

How It Is Used in Play

  • Flexibility: By holding back …d5, Black keeps several pawn breaks (…c5, …e5, …d5) in reserve and can adopt hyper-modern setups.
  • Transpositions: From the initial position many famous systems arise:
    • Nimzo-Indian: 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4
    • Queen’s Indian: 1. d4 Nf6 2. c4 e6 3. Nf3 b6
    • King’s Indian: 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7
    • Bogo-Indian, Grünfeld, Benoni, & Benko Gambit are also Indian Defences.
  • Move-order subtleties: White can sidestep certain lines (e.g., 2. Nf3 avoids the Nimzo), so specialists study transpositions deeply.

Strategic and Historical Significance

The Indian Game spearheaded the hyper-modern revolution of the 1920s, challenging classical dogma that center pawns must be occupied early. Figures like Aron Nimzowitsch, Richard Réti, and later Ernst Grünfeld showed that controlling the center with pieces and attacking it with timely pawn breaks could be equally sound. After World War II the King’s Indian became a battleground for Botvinnik, Bronstein, Fischer, Kasparov, and modern stars such as Radjabov and Nakamura.

Famous Encounters

  1. Fischer – Spassky, Reykjavík 1972 (Game 3): Nimzo-Indian with Fischer innovating 4. Qxd4!?
  2. Kasparov – Kramnik, Linares 1993: A razor-sharp King’s Indian main line that ended in perpetual check.
  3. Topalov – Anand, Sofia 2010: Grünfeld Defence; Anand’s exchange sacrifice on d4 became a modern classic.

Interesting Facts

  • The name “Indian” originates from the 19th-century “Indian Defence” 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. d3, then generalized to d4 openings in early 20th-century tournament books.
  • ECO code E94 (King’s Indian, Classical) is nicknamed “The Hand-to-Hand Combat of Chess” for its tactical violence.
  • Among top-level events, the Indian family of openings is second only to the Sicilian in raw frequency.

Black Knights Tango

Definition

The Black Knights Tango (also called the Mexican Defence or ECO A57–A59) arises after 1. d4 Nf6 2. c4 Nc6!? (the pure Tango) or via 1. d4 Nf6 2. c4 e6 3. Nf3 Nc6. Black’s two knights dance toward the center—first to f6, then c6—resembling tango partners taking alternating steps.

Key Ideas and Usage

  • Provocation: The early …Nc6 invites d5, when the e5-break becomes thematic after …Nb8-d7 or …Ne5.
  • Piece Activity: Black swiftly develops pieces while keeping the pawn structure flexible.
  • Transpositional Weapon:
    • Can transpose to a Queen’s Indian (…b6), a Chigorin (…d5), or a Pirc/Modern (…g6).
    • GMs often use it as a surprise line to avoid heavy home preparation in mainstream Queen’s Gambit theory.

Strategic Themes

Because Black has not committed the c-pawn or e-pawn, plans can switch rapidly:

  • Central Breaks: …e5 is the signature strike; …d5 or …c5 often follow.
  • Minor-piece Coordination: The queen’s knight may retreat to b8, d4, or e5, echoing a tango step back and forth.
  • King Safety: Black can castle kingside quickly via …g6 & …Bg7 or simply …Be7.

Example Line

Pure Tango main line:

1. d4 Nf6
2. c4 Nc6
3. Nf3 e6
4. a3 d5
5. Nc3 dxc4 
6. e4 Na5

Here Black has provoked White’s center and hopes to undermine it with …c5 or …Nb3 later.

Famous Games Featuring the Tango

  1. Karpov – Kasparov, World Championship (Seville) 1987, Game 7: Kasparov unleashed the Tango to surprise Karpov and held an important draw.
  2. Short – Radjabov, Wijk aan Zee 2003: A sparkling attacking win for Black featuring the thematic …e5 break and piece sacrifice on f2.
  3. Kamsky – Shirov, FIDE Knock-Out 1999: Shirov used the Tango to reach an unbalanced middlegame and eventually prevailed in a queen endgame.

Interesting Facts & Anecdotes

  • The nickname “Mexican Defence” honors GM Carlos Torre, who employed 2…Nc6 in the 1920s, but the Tango brand was popularized by American GM Georgi Orlov in the 1990s with his book “The Black Knights Tango.”
  • Because the knights oscillate (f6-g4-e5-c6-b4-d3), commentators sometimes joke that they have “castled by themselves.”
  • Despite looking adventurous, modern engines evaluate the Tango as roughly equal, making it a sound yet off-beat alternative for creative players.
