King's Indian Defense
The ultimate counterattacking defence to 1.d4: give White the centre, then bury the king under the …f5–f4–g5 pawn storm.
The King’s Indian Defense (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7) is the most ambitious answer to 1.d4. Black lets White build the whole classical centre, then attacks it with pieces and pawn breaks — and in the main lines launches the most feared kingside pawn storm in chess: …e5, …f5–f4 and …g5–g4 marching straight at White’s king while White races on the queenside.
This is the defence of legends — Bronstein, Fischer, Tal and Kasparov used it to play for a win with Black against the strongest opposition on earth. The price is comfort: Black concedes space and must know the typical race positions. The reward is a game where Black, not White, dictates the terms. This guide covers the main systems, the attacking plans, and how the KID performs across rating levels.
Main lines
- 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5The Classical — after 7.O-O Nc6 8.d5 Ne7 the famous Mar del Plata race begins: Black storms the kingside, White the queenside.
- 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3The Sämisch — White fortifies e4 and castles long; Black counters with …c5 breaks or the thematic exchange sacrifice on c3.
- 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f4The Four Pawns Attack — White grabs maximum space; Black hits back with …c5 and …e6, targeting the over-extended centre.
- 1.d4 Nf6 2.c4 g6 3.g3 Bg7 4.Bg2 O-OThe Fianchetto Variation — White’s safest system; Black switches plans to central and queenside play rather than the pawn storm.
Key plans & ideas
- Stake the claim with …e5: the central counter defines the KID; when White closes with d5, the great pawn race begins.
- Storm the kingside: …f5, …f4, …g5–g4 and …Rf7–g7 — Black attacks the king while White plays for c5 and the c-file; speed decides.
- Reroute the knights: …Ne8 or …Nd7 clears the f-pawn’s path and heads for the blockading squares; the f6-knight is the engine of the attack.
- Trade the right pieces: keep the g7-bishop and the attacking knights; a well-timed …Nxd5 or …exd4 switch punishes slow White play.
- Against the Fianchetto, change gears: with White’s king safer, switch to …Nbd7, …e5 and queenside play with …a6 and …Rb8 instead of the storm.

Coming soonFrequently asked questions
Is the King’s Indian Defense good for club players?
Yes — it comes with the clearest attacking plan in chess: …e5, …f5–f4, …g5 and mate. You will lose some games on the queenside, but you will win far more by checkmate, and the plans repeat from game to game.
Is the King’s Indian sound at top level?
It has been a world-championship weapon for Fischer and Kasparov, and remains fully playable today. Elite players respect White’s resources in the Classical and Bayonet lines, but no refutation exists — it is a matter of taste, not soundness.
King’s Indian or Grünfeld — which should I choose?
Both fianchetto the king’s bishop; the difference is the centre. The KID lets White build it and attacks it later with pawns; the Grünfeld strikes it immediately with …d5 and pieces. Attackers pick the KID, dynamic-equality players the Grünfeld.
How does White try to beat the King’s Indian?
The main tries are the Classical race (where White’s queenside attack is statistically fast), the Sämisch clamp with f3, the space-grabbing Four Pawns, and the safety-first Fianchetto — each demands a different plan from Black, which is the KID’s real learning curve.
