King's Indian: Hypermodern Opening Family
King's Indian
Definition
The term “King’s Indian” groups together a family of opening systems characterized by Black fianchettoing the king’s-side bishop on g7 and placing the king safely behind a pawn shield on g6–g7–f7–e7 (or its mirror image when played by White). In practice, most players use “King’s Indian” as shorthand for the King’s Indian Defense (KID) that arises after 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6, but the related King’s Indian Attack (KIA) where White adopts a similar structure against …e5 or …c5 setups also belongs to the same conceptual family.
Typical Move Order & Main Branches
The most common KID tabiya is reached via
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5. From here an enormous tree of variations blooms:
- Mar del Plata (Classical): 7. O-O Nc6 8. d5 Ne7 where opposite-wing pawn storms are typical.
- Bayonet Attack: 7. O-O Nc6 8. d5 Ne7 9. b4! — White gains queenside space.
- Sämisch System: 5. f3 aiming for 6. Be3 and a massive kingside clamp.
- Fianchetto Variation: 3. g3 or 4. g3, a positional line once thought to “refute” the KID.
- Four-Pawns Attack: 4. e4 d6 5. f4 O-O 6. Nf3 c5 where White grabs central space at the cost of king safety.
- King’s Indian Attack: 1. Nf3 followed by g3, Bg2, d3, Nbd2, e4, often vs. …e6 or …c5.
Strategic Ideas
The King’s Indian is a quintessential example of the hypermodern philosophy: allow the opponent to occupy the center, then undermine and destroy it later.
- Dark-Square Grip: Black’s Bg7 and pawn chain d6-e5 exert lasting pressure on d4 and e4.
- Pawn Storms: In many main lines Black advances …f5, …g5, and sometimes …h5-h4 to attack the white king, while c7-c6 or …b5 counters queenside expansion.
- Piece Activity: Knights often land on f4, g4, e5 or d4; the “KID bishop” on g7 can become a monster once the long diagonal opens.
- Timing Is Everything: Because White’s queenside play (c5, b4-b5, a4) tends to be faster on the clock, Black must launch the kingside initiative with accurate, even sacrificial, energy.
Historical Significance
Though analyzed in the 19th century, the King’s Indian did not gain world-class acceptance until the 1940s, when
pioneering grandmasters such as Isaac Boleslavsky, David Bronstein, and later
Miguel Najdorf demonstrated its dynamic potential.
In the post-war era it became a principal weapon for Bobby Fischer and
Garry Kasparov, both of whom used it to score critical wins in World Championship cycles.
Its popularity waned slightly in the 2010s due to powerful computer prep favoring White in certain critical lines,
but modern specialists (e.g., Teimour Radjabov, Hikaru Nakamura,
Alireza Firouzja) continue to rejuvenate the defense with fresh ideas.
Famous Games & Illustrative Examples
-
Kasparov – Kramnik, Linares 1994
(Mar del Plata, sacrificial king hunt)
- Fischer – Gligorić, Varna Olympiad 1962 (Fianchetto Variation; Black equalizes then outplays the American legend, showcasing the resilience of the KID setup.)
- Radjabov – Aronian, Wijk aan Zee 2014 (Bayonet Attack; a modern computer-prepped pawn sacrifice leads to rich middlegame complications.)
Interesting Facts & Anecdotes
- The nickname “KID” (King’s Indian Defense) is so entrenched that some commentators speak of a player “joining the KID cult.”
- In the 1953 Zürich Candidates, Bronstein predicted the opening would one day become an “ever-green forest of variations,” a prophecy fulfilled by today’s towering databases.
- Boris Spassky used the King’s Indian Attack to defeat Tigran Petrosian in their 1966 World Championship match, a rare White victory employing the system at the very highest level.
- Engines rate many KID positions as slightly worse for Black, yet practical results for humans remain roughly equal—highlighting the opening’s imbalance and potential for counter-chances.
When to Use the King’s Indian
Choose the KID if you:
- Enjoy sharp, double-edged battles with chances for creative piece play and sacrificial attacks.
- Are comfortable playing with less initial space and willing to gamble on dynamic counterplay.
- Prefer flexible opening repertoires where transpositions (e.g., to Grunfeld, Benoni, Pirc) are possible.
Conversely, risk-averse players or those who thrive on long, dry endgames may find the King’s Indian too volatile for their taste.
