King’s Indian Defense
King’s Indian Defense
Definition
The King’s Indian Defense (often abbreviated “KID”) is a hyper-modern chess opening that arises after the moves 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7. Black allows White to occupy the center with pawns, planning to undermine and attack it later, often launching a powerful counter-attack on the kingside. The opening gets its name from Black’s fianchettoed king’s-side bishop, which exerts long-range pressure from g7.
Typical Move Order & Tabiya
The most common continuation to reach the main tabiya is:
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5
After 6…e5, a characteristic King’s Indian pawn structure appears: Black’s pawns on d6 + e5 challenge White’s d4 pawn, while White usually enjoys space with pawns on d4 + e4 + c4. This “Samisch-Mar del Plata” tabiya is a springboard for many famous attacking battles.
Strategic Themes
- Central Tension: Black strikes with …e5 or …c5. White must decide whether to maintain, release, or transform the center.
- Kingside vs. Queenside Race: In the Classical lines, Black storms the kingside with …f5, …g5, …g4 while White expands on the queenside with b4, c5, and a4.
- Piece Activity over Pawns: As a hyper-modern opening, the KID emphasizes piece pressure (especially the dark-squared bishop) rather than immediate pawn occupation of the center.
- Closed Center: After …e5 and d5, the center often locks, giving each side clear wings to attack.
Historical Significance
Although known in the 19th century, the King’s Indian was considered risky until the 1940s, when Soviet stars such as Isaac Boleslavsky, David Bronstein, and later Garry Kasparov demonstrated its dynamism at the highest level. The defense became a mainstay of aggressive players and remains one of the most deeply analyzed openings in modern chess theory.
Key Variations & Example Lines
- Classical (7…Na6 or 7…Nc6): 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.O-O Nc6 (or 7…Na6). Leads to the famous Mar del Plata attack.
- Sämisch: 5.f3. White fortifies e4 and plans g4. Black counters with …c5 or the sharp …e5 …Nh5 …f5 plan.
- Fianchetto Variation: 3.g3. White mirrors Black’s fianchetto and aims for solid central control. The game is more positional.
- Averbakh: 5.Be2 O-O 6.Bg5. White pins the knight and delays kingside castling.
- Four Pawns Attack: 5.f4 exf4 6.Bxf4. White marches four central pawns for a direct assault; Black seeks counterplay on the dark squares.
Illustrative Games
- Garry Kasparov – Veselin Topalov, Wijk aan Zee 1999 (Classical, Mar del Plata) – Kasparov’s legendary sacrificial win featuring a queen sacrifice and two connected passed pawns.
- Bobby Fischer – Tigran Petrosian, Candidates 1971, Game 6 (Sämisch) – Fischer dismantles Petrosian’s solid setup with accurate central play.
- Vladimir Kramnik – Garry Kasparov, Linares 1994 (Fianchetto) – Kramnik’s positional squeeze shows how harmless the KID can look when White keeps the center fluid.

Modern Usage
The KID remains a primary weapon for dynamic grandmasters such as Hikaru Nakamura and Teimour Radjabov. In online blitz, its flexible pawn structure lends itself to surprise reversals, while in classical play, its complexity offers numerous chances for creative preparation.
Interesting Facts & Anecdotes
- Garry Kasparov famously declared, “If you look at the King’s Indian pawn structure and don’t feel butterflies, you are not a real attacking player!”
- Despite being an opening for Black, Magnus Carlsen has occasionally adopted it with White by playing 1. Nf3, 2. g3, 3. Bg2, and then transposing the colors.
- The defense featured prominently in the movie Searching for Bobby Fischer, where young Josh Waitzkin unleashes a thematic …f5 break.
- Computer engines long preferred White, but recent neural-net evaluations have closed the gap, reaffirming the KID’s resilience.
