1. d4 Nf6 2. c4 g6
The King’s Indian Defense is a hypermodern chess opening for Black against 1. d4, defined by 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6. Instead of occupying the center immediately with ...d5 like the Queen’s Gambit Declined, Black fianchettoes the bishop to g7, lets White build a broad pawn center, and then attacks that center with ...e5 or ...c5. The result is one of the most combative defenses in chess: unbalanced positions where Black plays for a win, not for equality.
The standard move order is 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6, after which Black castles short and the real fight begins. The setup is flexible, and Black can reach the same position through 1... g6 or 2... d6 move orders, because the defining features are the moves themselves: knight on f6, bishop on g7, pawn on d6, king castled. White’s fifth move sets the variation: 5. Nf3 with Be2 is the Classical, 5. f3 the Sämisch, 5. f4 the aggressive Four Pawns Attack, and 5. Be2 with Bg5 the Averbakh. Against each, Black answers the big center with a timed pawn break: ...e5 in the Classical, ...c5 against the Sämisch, Four Pawns, and Averbakh. The game sharpens immediately.
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O exd4 8. Nxd4 Re8
White develops naturally and Black strikes the center with ...e5. Taking on d4 and putting the rook on e8 puts immediate pressure on White’s e4-pawn instead of locking the center. Black follows with ...c6 and a well-timed ...d5 break, opening the position for the g7-bishop while White is still coordinating.

White trades queens hoping for a quiet, slightly better endgame. Black should not fear it: the d4-square becomes an outpost, the g7-bishop stays strong, and the greedy 9. Nxe5 runs into 9... Nxe4: now 10. Nxf7 loses a whole piece to the zwischenzug 10... Bxc3+ 11. bxc3 Kxf7, and even the better 10. Nxe4 Bxe5 only restores material equality with the more comfortable game for Black. Knowing this tactic turns White’s "safe" choice into a pleasant game for Black.

White’s 5. f3 builds a fortress around e4 and prepares Be3, Qd2 and a kingside pawn storm. The modern antidote is the immediate 6... c5 pawn sacrifice: if White grabs it and trades queens, Black’s lead in development, pressure down the d-file, and the raking g7-bishop give full compensation: ideas like ...Nd7, ...Bxc3 and ...Nde5 win the pawn back or worse. If White declines with 7. d5, Black gets a favorable Benoni-style game with ...e6.
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f4 O-O 6. Nf3 c5
White grabs maximum space with four center pawns, ambitious but loose. Black hits back at once with ...c5; after 7. d5 e6 the center comes under fire before White finishes developing, and breaks like ...exd5 and ...b5 rip open lines against the stretched pawn front. Black should welcome this variation: the more pawns White pushes, the more targets the g7-bishop and Black’s pieces get.
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Be2 O-O 6. Bg5 c5
The bishop on g5 discourages an immediate ...e5, so Black switches to the other break: 6... c5. After 7. d5 e6 Black challenges the center Benoni-style, and tricks against the loose g5-bishop and the b2-pawn (...exd5 followed by ...Qb6) force White to play precisely. The g5 pin looks annoying but rarely achieves anything concrete once Black’s counterplay starts.
Facing the King’s Indian with White, the first rule is psychological: Black chose this opening to attack, so do not drift into a passive setup and wait. Your space advantage is real. Use it. In the Classical lines with Nf3 and Be2, the principled approach is to meet ...e5 by keeping the tension or closing with d5, then race on the queenside with c5 and b4 while Black storms the kingside; tempo counts, so every queenside move matters. The Sämisch with f3, Be3 and Qd2 is the most direct attacking try (White castles long and throws kingside pawns), but be ready for Black’s ...c5 counter, including the pawn-sacrifice lines where grabbing material hands Black dangerous activity. The Four Pawns Attack wins space but stretches you thin; only play it if you know the ...c5 and ...e6 counters concretely. If you prefer quieter chess, the Exchange Variation (dxe5 and a queen trade) takes the sting out of Black’s attack, though it concedes any real ambition and still contains tactical tricks against careless play: after 9. Nxe5 Nxe4, the follow-up 10. Nxf7 loses a piece to 10... Bxc3+, and even the best 10. Nxe4 Bxe5 leaves Black comfortably equal. Whatever you choose, the worst results come from half-measures: pick a plan, know Black’s standard breaks against it, and execute on your side of the board faster than Black executes on theirs.
Occupy the center with pawns on d4, e4 and c4, develop behind it, and use the extra space to attack where Black is weakest: usually the queenside with c5, b4 and a file-opening break, or the kingside directly in Sämisch setups with Be3, Qd2 and h4. Keep the center stable: if it collapses, the g7-bishop and Black’s pieces flood through. Speed matters more than safety in the race positions.
Castle quickly, then strike the center with the right break for the variation: ...e5 against Classical setups, ...c5 against the Sämisch, Four Pawns and Averbakh. Open lines for the g7-bishop, meet wing attacks with central counterplay, and look for the standard tactics against e4, d4 and b2. The King’s Indian rewards the player who attacks first with the better-prepared break.
The King’s Indian belongs to the hypermodern school that emerged in the early twentieth century, which argued that the center could be controlled by pieces from a distance and attacked later, rather than occupied immediately with pawns. For a long time the defense was viewed with suspicion for exactly that reason: conceding the center looked like a concession. The generation after World War II proved otherwise, and the opening became a main-line battlefield at the highest level. Its reputation rests on the players who trusted it for entire careers: Bobby Fischer used the King’s Indian as a career-long weapon, and it was Garry Kasparov’s main defense to 1. d4 for over a decade, producing some of the most famous attacking games ever played. It remains a favorite of ambitious players at every level who want winning chances with Black.
More than an opening: a complete system against 1.d4 for players brave enough to head into the complications.
Welcome to this course on the King’s Indian Defense, one of the most dynamic and complex openings in chess. The essence of the KID lies in completing development quickly and then striking at White’s center. We should begin by developing the knight to f6, taking control of the important central squares e4 and d5.
As we have already discussed, White aims to occupy the center with his pawns. In response, we should push our pawn to g6, preparing to develop the dark-squared bishop along the powerful a1–h8 diagonal.
The most popular move for White, preparing pawn to e4. As we will later see, White has many different ways to develop and attempt to gain an advantage, but we should be able to secure an active position with counterplay. We continue our setup by developing the bishop to g7.
White has conquered the center, at least for the moment, and is currently threatening to chase away the knight on f6. To counter this, we should place our pawn on d6, which marks the characteristic King’s Indian setup.
White develops the light-squared bishop before deciding how to bring out the other pieces.
White develops the other bishop to e3. We continue with knight to c6, applying pressure on the d4 pawn.
White plays the most principled move, as we were ready to strike with the pawn to e5. Our knight now jumps to b4.
White will play this move sooner or later. Our knight retreats to a6.
White decides to take control of the c5 square, aiming to restrict our queenside play. However, this doesn’t aid White’s development, so we should react with the pawn to c5.
White plays the strongest move, keeping the tension. We now counter in the center with pawn to e6.
The final position is now very unclear. We'll play in the center with exd5 and Re8, with good counterplay.
This variation is known as the Sämisch Variation. White strengthens his center with the pawn, but this also makes kingside development more difficult. We simply castle.
Now we start our active counterplay against White's center with pawn to c5, offering a pawn sacrifice.
White decides to remain flexible for now and develops his kingside knight. We respond by placing our queen on a5, pinning the knight on c5 and keeping pressure on the queenside.
The knight is headed to b3, attacking our queen. We respond by capturing on d4.
We return our queen to b6, forcing White to take on d4 with the bishop, which gives us a tempo for developing the queenside knight.
Our queen returns to d8.
We develop the knight to c6, attacking White’s important dark-squared bishop.
We continue our queenside development with the bishop to e6.
The pawn structure resembles a typical Maróczy Bind structure. We should play on the queenside with rook to c8, pawn to a6, and knight to e5, targeting the c4 pawn.
White stabilizes the central situation, which gives us the chance to strike on the queenside with the typical pawn push to b5.
After White takes the pawn, we continue with pawn to a6, opening the a-file for our rook.
We obtain very good compensation for the pawn, as can be seen from the exemplary games. Socko, B. - Kempinski, R., 0-1, Bundesliga 2014-15, 2015, lichess.org/gQUWg9GE Bogdanovski, Vlatko - Kempinski, Robert, 0-1, EU-Cup 18th, 2002, lichess.org/9tLdvifw
White refuses the pawn sacrifice and opts for a Benoni‑type structure. We play pawn to e6, opening the e‑file.
We take on d5 with the pawn.
Queenside counterplay is essential for us in the Benoni, so we begin with pawn to a6, taking control of b5 and preparing pawn to b5 ourselves.
White naturally prevents our pawn push to b5. We continue by bringing the rook to e8, placing it on an active square. It’s also very important to keep an eye on the h3 square, preventing White from comfortably developing the kingside knight to f2 via h3.
Now that White has committed his knight to e2, we block our light‑squared bishop and develop the knight to d7.
We continue with pawn to h5, a typical advance in these positions, harassing White’s knight.
The position is very complicated. Generally, our idea is to first chase White’s knight with pawn to h4, and then continue with knight to h7 and pawn to f5, striking at White’s center. Here is an exemplary game. Wang, Yue - Shchekachev, Andrei, 1/2-1/2, Bad Zwesten op 7th, 2003, lichess.org/3ZzpB20o
White decides to win a pawn, which will also lead to a queen exchange. Although this may look strange at first glance, we keep good compensation for the pawn thanks to White’s lag in development and the weakness of the d4 square.
We recapture the queen.
We develop the knight to c6, defending the e7 pawn and eyeing the important squares d4 and b4.
This is the most direct move for White. We should play knight to d7, attacking the bishop on c5 and hitting the b2 pawn with our powerful dark‑squared bishop. Now White has to decide with which piece to capture the pawn on e7.
We capture the knight.
We take the pawn on b2, attacking White’s rook on a1.
Finally, we remove the rook from the attack with rook to e8.
In this position, we have good compensation since we will be able to quickly develop our pieces to good squares, which cannot be said for White’s pieces. Also, White’s c4 pawn may become a target in the near future. Here are some exemplary games.

Yes, with one caveat. The setup is easy to learn (knight to f6, bishop to g7, pawns to g6 and d6, castle), and it works against almost everything. The caveat is that you must learn the pawn breaks (...e5 and ...c5) and actually play them; the setup alone is not the opening.
Yes. It has been played at world championship level for decades and was a career-long weapon for Bobby Fischer and Garry Kasparov’s main defense to 1. d4 for over a decade. White gets space and Black gets dynamic counterplay; engines rate the resulting positions close to balanced, and in practical play Black’s winning chances are excellent.
White’s main tries are the Classical (Nf3 and Be2, racing on the queenside while Black attacks the kingside), the Sämisch (f3, Be3 and Qd2 with a direct attack), the Four Pawns Attack (maximum space), and the quieter Exchange Variation with an early dxe5 and queen trade. Each demands that White know Black’s standard counters concretely.
The King’s Indian Defense is a Black opening against 1. d4, built around ...Nf6, ...g6, ...Bg7 and ...d6. The King’s Indian Attack is White playing a mirror of the same setup (Nf3, g3, Bg2, d3) against various Black defenses. Same structure, opposite color and very different theory.
Because it refuses to trade activity for safety. Black invites White to build a big center, then attacks it with pawn breaks, and in the main lines both sides attack on opposite wings; games are decided by who breaks through first, not by who shuffles more accurately. It is one of the few defenses where Black regularly checkmates the white king.
