King's Indian Attack (KIA)
Definition
The King’s Indian Attack is a flexible White opening system characterized by the pawn and piece configuration g2–g3, Bg2, Nf3, d3, O-O, Nbd2, and e2–e4. Rather than a single, fixed move order, it is a system: White aims to reach the same middlegame structure against a wide variety of Black set-ups (French, Sicilian, Caro-Kann, 1…e5, and even the Nimzo/Queen’s Indian complex). Strategically, it is the mirror image of the King’s Indian Defence, but with an extra tempo for White.
Typical Move Order
One of the most common sequences is:
- 1. Nf3 d5 2. g3 Nf6 3. Bg2 e6 4. O-O Be7 5. d3 O-O 6. Nbd2 c5 7. e4
The same structure can arise from 1. e4 e6 2. d3 or 1. c4, 1. g3, or even after a Sicilian with 1. e4 c5 2. Nf3 e6 3. d3. The route is less important than the destination: a solid, hyper-modern set-up where White delays central occupation until the moment is ripe.
Strategic Ideas
- Pawn breaks: The thematic thrusts are e4-e5 (gaining space and fixing the pawn chain) and sometimes f2-f4-f5 or g3-g4-g5 to rip open the kingside.
- Piece placement: Knight maneuvers like Nf3–h4–f5 or Nf3–g5, queen on e2, rooks on e1 and f1, and the dark-squared bishop pointing at h7 (or h2 if roles are reversed).
- Closed center, wing attack: After …d5–d4 or …c5–c4 by Black, the center locks and White begins a slow-motion storm on the kingside reminiscent of the KID for Black.
- Reversed tempo advantage: Because White has an extra move compared to the traditional King’s Indian Defence, attacks can crash through startlingly fast.
Historical Notes
• The set-up was championed in the 1950s by Hungarian GM Gedeon Barcza, giving rise to
the early name “Barcza System.”
• It gained world-wide fame when Bobby Fischer adopted it as a near-universal weapon
when he wanted to avoid heavy opening theory. Between 1960 and 1972 he scored
an extraordinary 80 % with the KIA.
• Modern specialists include Gata Kamsky, Sergey Karjakin, and Hikaru Nakamura,
who employ it as a surprise weapon in rapid and blitz.
Illustrative Game
Fischer – Myagmarsuren, Sousse Interzonal 1967
Fischer uncorked the classic kingside pawn storm: f2-f4, f5, g4, g5, h4, h5! Black’s king was mated on h7 despite apparently solid defences.

Interesting Facts
- The KIA can arise against almost any Black reply; some club players adopt it exclusively to avoid memorizing separate openings for the French, Sicilian, and Caro-Kann.
- Because it is a “reversed” defence, theory tends to be lighter—yet engines now show the system is objectively sound, not merely a sideline.
- Grandmaster John Nunn once joked that learning the KIA saves shelf space: “One slim pamphlet replaces a dozen thick Sicilian tomes.”
When to Choose the KIA
Opt for the King’s Indian Attack when you want:
- A single, universal repertoire versus multiple Black defences.
- Strategic middlegames with rich attacking chances and a familiar pawn skeleton.
- To sidestep heavy opening theory and reach playable positions on your terms.
Key Takeaways
- Flexible system: reach it through 1. Nf3, 1. e4, or 1. g3.
- Strategic themes revolve around the e4-e5 break and a kingside pawn storm.
- Historically endorsed by Fischer; still a potent surprise weapon today.
