Queen’s Indian Defence
Queen’s Indian Defence
Definition
The Queen’s Indian Defence is a hyper-modern chess opening that arises after the moves 1. d4 Nf6 2. c4 e6 3. Nf3 b6. Black immediately questions White’s central ambitions by preparing to fianchetto the queen’s bishop to b7 rather than occupying the center with pawns. The opening is classified in the Encyclopaedia of Chess Openings (ECO) under the codes E12–E19.
Typical Move Order & Main Variations
The starting position of the Queen’s Indian is reached after:
1. d4 Nf6 2. c4 e6 3. Nf3 b6
Popular fourth moves for White lead to distinct branches:
- 4. g3 – Main Line (Fianchetto Variation)
- 4. Nc3 – Classical Variation
- 4. a3 – Petrosian Variation, preventing …Bb4+
- 4. e3 – Solid Line, transposing to Catalan-type structures
- 4. Bg5 – Miles Variation, an immediate pin on the knight
The defining moves …Bb7, …Be7, …d5 (or …c5) together with flexible piece play give Black a sound, resilient set-up.
Strategic Ideas
- Control of the Light Squares: By placing the bishop on b7, Black eyes the crucial e4 square and the long diagonal toward a8.
- Central Flexibility: Black delays …d5, choosing the optimal moment to strike in the center with …d5, …c5, or sometimes …e5 in conjunction with …Bb4+.
- Minor-Piece Activity: Knights often land on e4 or c6, while bishops harmonize on b7 and e7; exchanges on d4 can relieve space pressure.
- Pawn Structure: The typical pawn chain d5–e6 (after …d5) resembles the Queen’s Gambit Declined, but with the added fianchettoed bishop giving Black dynamic chances.
- Endgame Considerations: In many endings the b7 bishop may become a “large pawn” if the long diagonal is blocked, so Black must keep the position fluid.
Historical Context
The Queen’s Indian was developed in the early 20th century as part of the
hyper-modern revolution led by players like Richard Réti and Aron Nimzowitsch.
Max Euwe and José Capablanca experimented with the opening, but its
systematic adoption came later.
The defence gained elite status when Efim Geller and Tigran Petrosian played it regularly in the 1950s–60s, showcasing its solidity against 1. d4. During the Kasparov–Karpov World Championship matches of the 1980s, it was a frequent battleground, firmly entrenching it in top-level repertoires.

Modern Use & Practical Tips
- Against the Main Line 4.g3: Learn both …Ba6 (E15) and …Bb7 (E14) approaches to vary your repertoire.
- Remember the …Bb4+ Device: If White’s knight is on c3, the pin can forcibly alter pawn structures in your favor.
- Be Patient: Many positions are slightly passive; timely breaks (…d5 or …c5) are critical to liberate your pieces.
- Watch the Clock: The defence can transpose to Catalan or Bogo-Indian lines; understanding plans is more valuable than deep memorization.
