Key Insights

Attack Timing
black
High Impact

The ...f5 Break Succeeds 75% of the Time When Played After ...Nd7

What this means
In 35 King's Indian games, you played ...f5 in 22 of them. When prepared with ...Nd7 first (rerouting the knight from f6 to support f5), you won 9 out of 12. When you played ...f5 without ...Nd7 preparation, you won only 4 out of 10. The unprepared f5 often leaves the e6 square weak and your knight on f6 misplaced.
How to improve
Follow the standard King's Indian recipe: (1) ...Nbd7, (2) ...f5, (3) ...Nf6 back to support the attack. The knight reroute via d7 is not a waste of time — it ensures f5 has proper support. After ...f5 exf5 gxf5, your knight returns to f6 aiming for g4 or h5, and the g7 bishop comes alive. Never play ...f5 when your knight is still blocked on d7 without Nf6 being available.

High Impact

White's c5 Break Ignored in 45% of Games, Costing an Average of 0.8 Pawns

What this means
When White achieved c5 in the Classical variation, you failed to react with ...a5 (preventing queenside expansion) in 7 out of 15 games. In those 7 games, White's queenside attack succeeded before your kingside attack, resulting in 5 losses. The engine consistently recommends ...a5 as the critical defensive resource.
How to improve
In the Classical King's Indian (d4 Nf6 c4 g6 Nc3 Bg7 e4 d6 Nf3 O-O Be2 e5 d5), always play ...a5 when White plays c5. This stops b4-b5 and gives your rook activity on the a-file. The timing is usually right after White plays c5 — respond immediately with ...a5. Don't get tunnel vision on the kingside; a quick ...a5 takes one move but saves your entire queenside.

Piece Activity

Bishop on g7 Blocked in 60% of Games After Move 20

What this means
Your g7 bishop, the most important piece in the King's Indian, remains blocked behind your own pawns (e5, d6) past move 20 in 21 of 35 games. When the bishop is active (after ...f5 or ...c6/...d5), your win rate is 68%. When it stays blocked, it drops to 36%. The blocked bishop means your entire opening setup has failed to achieve its purpose.
How to improve
The entire King's Indian is built around activating the g7 bishop. Your plan should always include one of: (1) ...f5 followed by ...f4, opening the g7 bishop's diagonal, (2) ...c6 and ...d5, challenging the center directly, or (3) ...Nh5-...Nf4, forcing exchanges that open lines. If none of these are possible by move 15, reconsider whether the King's Indian was the right choice for that particular game.

Key Positions to Know

Critical concepts every King's Indian Defense player should understand

The King's Indian Fianchetto

Black's Bg7 controls the long diagonal a1-h8 and supports the ...e5 and ...f5 breaks. This bishop often becomes Black's most important piece, especially in the middlegame when lines open up after the central pawn pushes.

The ...f5 Pawn Break

Black's signature attack. After ...Nbd7, ...e5, and preparation, Black launches ...f5 to blow open the kingside. If f5 is achieved successfully, the g7 bishop comes alive and Black often gets a crushing attack.

Dueling Attacks

The King's Indian creates the ultimate strategic battle: White expands on the queenside with c5-d5, while Black attacks on the kingside with ...f5-f4. Both sides must be relentless — the first to break through wins.

Why Play the King's Indian Defense?

勝利への意志

単に引き分けを狙うのではなく、黒番で積極的に勝利を目指すプレイヤーにとって最高の選択肢の一つです。

Common Traps

Watch out for these dangerous tactical pitfalls

Fajarowicz Trap

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.dxe5 dxe5 8.Qxd8 Rxd8 9.Bg5 Re8? 10.Nxe5!

白がe5のブレイクに対して不用意にポーンを取ると、黒のピースが突然活性化し、白の中央が崩壊します。

Saemisch Knight Trap

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 O-O 6.Be3 e5 7.Nge2 c6 8.Qd2 Nbd7 9.Nc1? exd4 10.Bxd4 Ne5!

黒がクイーンサイドの防衛を完全に無視してキングサイドの攻撃に集中しすぎると、白に致命的なクイーンサイドの突破を許します。

Four Pawns Blunder

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? Bg4!

白が黒のf5ブレイクを過小評価すると、強力なポーンの嵐が白のキングを容赦なく追い詰めます。

Classical Queen Trap

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.O-O Nc6 8.d5 Ne7 9.b4? Nh5! 10.Re1 Nf4 11.Bf1 f5!

White's premature queenside expansion allows Black to launch a devastating kingside attack. The knight on f4 is secure, and ...f5 breaks open White's position. If White takes on f4, ...Rxf4 gives Black tremendous compensation. White should play 9.Ne1 or 9.Nd2 instead.

Frequently Asked Questions

Common questions about King's Indian Defense analysis

The King's Indian Defense begins with 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6. Black allows White to build a massive pawn center (e4 and d4) and then counterattacks it. The fianchettoed bishop on g7 — the cornerstone of the defense — controls the long diagonal and supports Black's kingside counterplay. After 5. Nf3 O-O 6. Be2 e5, the Classical position is reached: Black challenges the center with ...e5 and prepares the thematic ...f5 break.
The Classical Variation (1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O) is the main line. After 7...Nc6 8. d5 Ne7, the position splits: White typically chooses the Mar del Plata system (9. Ne1, preparing f3 and queenside expansion) or the Petrosian system (9. b4, restraining Black). The middlegame features a classic race: White attacks queenside with a4-b5, while Black storms the kingside with ...f5, ...f4, and ...g5.
The Saemisch Variation (4. e4 d6 5. f3) is one of the most aggressive systems. White plays f3 before developing the kingside knight, building a massive center and preparing Be3, Qd2, and often O-O-O followed by a kingside pawn storm. Black must react sharply — the typical response is 5...O-O 6. Be3 e5, accepting the centre challenge. Black often sacrifices pieces for a devastating attack. The Saemisch is theoretically demanding but extremely double-edged.
The Four Pawns Attack (4. e4 d6 5. f4 O-O 6. Nf3) is White's most ambitious try — establishing four pawns across the centre (c4, d4, e4, f4) and grabbing maximum space. Black must counterattack immediately with 6...c5! 7. d5 e6, undermining the centre. The Four Pawns Attack requires precise knowledge from both sides.
The Four Pawns Blunder occurs after 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? Bg4!. White's incorrect recapture 9. cxd5 allows the pin 9...Bg4!, and after 10. O-O Nxe4!, Black wins a centre pawn. White must play 9. e5! or 9. Nxd5 instead.
The Classical Queen Trap occurs after 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O Nc6 8. d5 Ne7 9. b4? Nh5! 10. Re1 Nf4 11. Bf1 f5!. White's premature b4 allows Black to plant the knight on f4 and launch a devastating kingside pawn storm. White should play 9. Ne1 (Mar del Plata) or 9. Nd2 before queenside expansion.
Garry Kasparov used the King's Indian throughout his career, most famously in his 1978 USSR Championship victory over Korchnoi where a piece sacrifice on f3 opened White's kingside catastrophically. The King's Indian is not just an opening — it is a statement of psychological intent. By allowing White to build a centre and demolishing it, Kasparov turned defensive positions into devastating counterattacks.
