Bogo-Indian Defense: Wade-Smyslov Variation

Bogo-Indian Defense: Wade-Smyslov Variation

Definition

The Wade-Smyslov Variation is a solid branch of the Bogo-Indian Defense that arises after the moves:
1. d4 Nf6 2. c4 e6 3. Nf3 Bb4+ 4. Bd2 Qe7 5. a3 Bxd2+ 6. Qxd2 b6. It combines two separate ideas—Bob Wade’s 4…Qe7 and Vasily Smyslov’s early …b6—into a single, cohesive system for Black.

Typical Move Order

The tabiya (main starting position) can be reached in several ways:

  • 1. d4 Nf6 2. c4 e6 3. Nf3 Bb4+
    4. Bd2 Qe7 (Wade’s move, sidestepping 4…Bxd2+ 5. Qxd2)
    5. a3 (forcing a decision) Bxd2+ 6. Qxd2 b6 (Smyslov’s idea)
  • An alternative transposition is 5. Nc3 b6 6. a3 Bxc3 7. Bxc3, but the pure Wade-Smyslov line keeps the queen on d2.

Strategic Objectives

After 6…b6 Black aims for a harmonious, Caro-Kann–style set-up: …Bb7, …d6 or …d5, and rapid kingside castling. Key themes include:

  • Piece Coordination: The dark-squared bishop slides to b7, eyeing the long diagonal while the light-squared bishop can later develop to e7 or b4.
  • Minor-Piece Flexibility: …Nc6 and …d5 can be played in one go if circumstances allow, but Black often prefers …d6/…Nbd7 first to remain solid.
  • Safe King: By delaying castling, Black prevents White from launching a quick pawn-storm on the kingside.
  • Unbalanced Pawn Structure: After the early exchange on d2, White’s queen sits awkwardly on d2, sometimes hindering natural development of the knight from b1.

Plans for Each Side

  • White often chooses between:
    • Queenside expansion with b4–b5, c5 and a later Rc1.
    • Central play: e4 followed by Rd1, strengthening the d-file.
    • Fianchetto setups with g3 and Bg2, echoing Catalan motifs.
  • Black usually pursues:
    • The classic …Bb7, …d6 (or …d5), and sometimes …Ne4.
    • Timely breaks with …c5 or …e5, challenging White’s center.
    • Queenside pressure: …a5 and …a4 restrain White’s pawns.

Historical Background

Bob Wade, a New Zealand-born British Grandmaster, popularized 4…Qe7 in the 1950s as a way to keep the bishop pair and avoid the well-theorized 4…Bxd2+. Vasily Smyslov, the seventh World Champion, enriched the system with 6…b6, combining Nimzo-Indian solidity with Queen’s Indian piece placement. Their ideas merged into the modern Wade-Smyslov Variation, classified as ECO E11.

Notable Games & Illustrative Example

A concise model game is given below. Notice how Black effortlessly completes development and equalizes.

  • Smyslov – Keres, Zürich Candidates 1953 saw Smyslov use the setup with Black to neutralize Keres’s initiative and draw comfortably.
  • Anand – Gelfand, Moscow 2012 (WCh, G2) featured the Wade idea; although Gelfand chose a different 6th move, his treatment transposed into the same structural themes.

Advantages & Drawbacks

  • Pros for Black
    • Sound, low-maintenance development scheme.
    • Flexible: can transpose into Queen’s Indian or Hedgehog structures.
    • White’s queen on d2 sometimes becomes a tactical target.
  • Cons for Black
    • Limited winning chances if White plays accurately.
    • Passive appearance may tempt White to seize space without risk.
    • The light-squared bishop can be hemmed in if Black mistimes …d6.

Interesting Facts

  • Bob Wade was renowned for his encyclopedic opening knowledge; he famously carried a suitcase of index cards, many of which featured notes on 4…Qe7.
  • Smyslov, an accomplished baritone, reportedly whistled operatic arias while analyzing the …b6 plan in Moscow’s Central Chess Club.
  • Modern engines rate the line as a hair shy of full equality for Black (≈ +0.20), making it a practical surprise weapon.
