What is the King's Indian Defense?

Can someone help me?

1. Initial moves and setup

The King's Indian Defense arises after the moves: 1. d4 Nf6 2. c4 g6.
Black's plan is to fianchetto the kingside bishop to g7, creating a strong defensive structure and eyeing the long diagonal.
Black will castle early on the kingside to ensure king safety.

2. Key concepts and strategy

Pawn breaks: Black's primary pawn breaks are ...e5 and ...c5, used to challenge White's central control.
Kingside attack: Black often aims for a kingside attack, especially if White closes the center with d5. This often involves pushing pawns on the kingside (f5, g5, h5) supported by pieces.
Counterplay on the queenside: White will often try to expand and attack on the queenside. Black needs to be aware of this and try to create counterplay, potentially with moves like ...a5 or ...c6 followed by ...b5, according to RagChess.
Piece maneuvers: Black will often maneuver pieces to support the attack, such as shifting the knight from f6 to e8, then to f5, or bringing the rook to f7 to support a kingside pawn push.

3. Important variations

Classical Variation: White develops knights to f3 and bishops to e2, controlling the center. Black typically responds with ...e5, leading to complex middlegames.
Sämisch Variation: White plays 5. f3, strengthening the e4 pawn. This often leads to sharp games with both sides castling on opposite wings, notes Chess.com.
Petrosian Variation: White pushes d5, closing the center. Black needs to maneuver to attack the kingside, while White will focus on the queenside, says Chess.com.
Four Pawns Attack: White advances all four central pawns (c4, d4, e4, f4) for maximum central control and a sharp game.

4. Tips for success

Understand the pawn breaks: Knowing when and where to play ...e5 and ...c5 is crucial for challenging White's center.
Kingside pawn storm: If the center is closed, be ready to launch a kingside pawn storm (f5, g5, h5) to create attacking chances.
Knight outposts: Look for opportunities to place a knight on d4, which can be a strong outpost.
Don't be afraid to be aggressive: The KID thrives on unbalanced positions and active play.
Focus on the middlegame: The KID often leads to complex middlegame positions, so practice tactical combinations and strategic plans.

5. Important considerations

The King's Indian is considered a risky opening, as it gives White an initial space advantage. However, it also creates unbalanced positions that can lead to decisive results.
It's important to be prepared for the various ways White can respond to the KID and have plans for both sides of the board.

Actually, for Clarity, the Kings Indian Defense is not just 1.d4 Nf6 2.c4 g6. Another component for it to be a Kings Indian Defense is there must be no early d5 or c5. So like, 3.Nc3 Bg7 4.e4 d6 is a Kings Indian. 3.g3 Bg7 4.Bg2 d6 is a Kings Indian.

An early d5, like 1.d4 Nf6 2.c4 g6 3.Nc3 d5 is not a Kings Indian, it is a Grunfeld.

An early c5, like 1.d4 Nf6 2.c4 g6 3.g3 c5 is not a Kings Indian either, it is a Benoni.

Now ...c5 a little later depends. 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f4 O-O 6.Nf3 c5 7.d5 e6 8.Be2 exd5 9.cxd5 is a Benoni by transposition (1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.f4 Bg7 8.Nf3 O-O 9.Be2 is the same position), but 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 O-O 6.Bg5 c5 is not a Benoni, it is actually the main response to the Averbakh Kings Indian.

So not all cases of 1.d4 Nf6 2.c4 g6 are the Kings Indian. It could still wind up a Grunfeld or Benoni.

Which AI did you use to plagiarize your response to the OP?

It's a good nuance, but I'd nuance it a bit more. There are certain lines -- the Four Pawns attack, the Averbach, the Saemisch -- where King's Indian players frequently or even almost always will choose to break with c5 rather than e5. One way to talk about it would be to say that they're choosing to transpose to a Benoni, and that's not wrong. They *are* Benonis. But when I look at my shelf and see that virtually all the King's Indian books I have recommend c5 against the Four Pawns Attack and Averbach, and a majority do so when it comes to the Saemisch, it's hard for me to say that these lines aren't part of the King's Indian universe too. It seems to me the sort of thing where you have to nuance your language, and potentially have different ways to talk about it, rather than affirming in advance that one line will forever be a Benoni and one forever a KID.

The break between the KID and Gruenfeld is, I agree, much clearer. Or at least it is if you're speaking as a King's Indian player, for whom I can't immediately think of any sidelines where you'd play d5. (I guess there's the Jobava London, but then you're not moving into a Gruenfeld either, it's just called a Jobava London -- either that or you transpose to a Pirc.) For a Gruenfeld player, on the other hand, it might be a bit more nuanced, because I believe Gruenfeld players do face a few sidelines where they prefer to play d6.

What does it matter?

But answer your question it was what google ai showed.
