King's Indian Defense
Hand over the center, then blow it up: pure counterattack against 1.d4
6 Chapters · 22 exercises
Origin
The King's Indian grows out of 1920s hypermodern thinking, when players like Nimzowitsch and Réti argued the center can be attacked from a distance rather than occupied. It became an elite weapon in the 1940s-50s through the Soviet school — Bronstein, Boleslavsky, Geller — and reached legendary status with Bobby Fischer and Garry Kasparov. Games from Mar del Plata 1953, between Najdorf and Gligoric, gave their name to the sharpest line of the opening.
Why it works
Black plays ...Nf6, ...g6, ...Bg7, castles short, and only then challenges White's center with ...e5 or ...c5. The g7 bishop eyes the long diagonal, and when the center locks with d4-d5 the game becomes a race: White pushes on the queenside with c4-c5, Black attacks the king with ...f5, ...f4, ...g5, ...h5. It is one of the few defenses where Black plays for a win from move one, without simplifying or asking for equality. The price is accepting less space for many moves, trusting the counterblow arrives in time.
In its favour
- +Gives Black a clear, violent attacking plan against the white king instead of passive defense.
- +The starting scheme (...Nf6, ...g6, ...Bg7, castle, ...d6) is the same against almost everything, cutting down early memorization.
- +Produces closed, unbalanced positions where understanding the plan matters more than equalizing material.
- +The g7 bishop stays a fearsome piece into the endgame, especially if the center opens.
The price
- −White has more space early, and if Black mistimes the counterblow the position is simply cramped.
- −In the Mar del Plata and Bayonet lines the slower side loses: they are tempo races with little room for improvisation.
- −The Sämisch (5.f3) and the Fianchetto demand completely different repertoires, multiplying the study load.
- −Against an early queen trade, as in the Exchange Variation, Black must patiently play a slightly worse endgame.
Chapters
1The Basic Setup and the Quiet SystemsHere you build the core setup — ...Nf6, ...g6, ...Bg7, short castling and ...d6 — and learn why Black gives up the center on purpose. The lines chosen are White's least aggressive: the Exchange Variation with queens off, the Four Knights System, 5.Bd3 and the ...c6 setup, all good for learning piece handling without immediate risk.0/5
2The Classical: ...e5 Against White's CenterWith 5.Nf3 and 6.Be2 White plays the main line and Black answers with ...e5, the blow that defines the opening. You study the Classical with ...Nbd7, the Petrosian System (with an early d4-d5) and Makogonov's prophylactic h3, learning to read when the center locks and which wing each side attacks.0/4
3The Fianchetto: When White Also Puts a Bishop on g2With g3 and Bg2 White neutralizes the long diagonal and the direct king attack gets harder. You meet the replies with ...e5, with ...c5 (Yugoslav Fianchetto) and the Panno setup with ...Nc6 and ...a6, understanding that the play here is more positional, fought over the ...b5 or ...f5 breaks.0/4
4Sämisch and Averbakh: The Pawn Wall5.f3 armors the e4 square, prepares Be3 and a g4-h4 assault; 5.Be2 followed by Bg5 (Averbakh) stops ...e5 for a moment. This chapter shows how Black breaks that wall — with a Benoni-style ...c5, with the Panno setup, or with the direct ...e5 against the Sämisch.0/4
5Four Pawns Attack and Benoni StructuresWhen White advances c4, d4, e4 and f4, the right reply is to attack that center at once with ...c5. You learn the transposition into Modern Benoni structures, where Black trades space for active pieces, the e-file and the a1-h8 diagonal.0/2
6Mar del Plata and the Bayonet Attack: The RaceThe theoretical heart of the opening: center locked by d4-d5, White pushing c4-c5 while Black plays ...Ne8, ...f5, ...f4, ...g5, ...h5 at the king. It includes the Bayonet Attack with 9.b4, the modern try to win the race by one tempo — the hardest and most decisive material in the course.0/3
