You play Black · play the main line move for move.
The Queen's Indian is the classical partner of the Nimzo: when White avoids Nc3 with 3.Nf3, Black controls e4 with pieces instead of pawns by fianchettoing the bishop to b7. For decades it was the elite's favourite equalizer (Karpov made a career of it), and its core lesson transfers to every opening you play: a square can be dominated without ever putting a pawn on it.
The idea in one line
Fianchetto with ...b6 and ...Bb7 to control e4 with pieces, develop calmly, castle, and choose the ...c5 or ...d5 break once White's setup shows its hand.
Key ideas
Everything is about e4: the b7-bishop and the f6-knight together stop White's e-pawn from advancing, and if White ever forces e4 through at a cost, Black strikes back in the centre.
4.g3 is White's main answer for the same reason: the g2-bishop opposes b7 on the long diagonal, and the fight over e4 and d5 defines the middlegame.
Black's position has no weaknesses; the price is patience. Stay flexible, keep the breaks in reserve, and strike with ...c5 or ...d5 exactly when White commits.
The modern 4...Ba6, hitting c4, is today's top-level main line; the classical 4...Bb7 shown here is simpler and teaches the opening's core idea first.
Plans for each side
White: Meet the fianchetto with g3 and Bg2, castle, then fight for e4 with Nc3 and Qc2; if Black ever relaxes, the space-gaining d5 or e4 advances give White a lasting pull.
Black: Put the bishop on b7, complete development with ...Be7 and ...O-O, keep e4 under piece control, and equalize with a timely ...c5 or ...d5; Black often welcomes simplification into a comfortable, level middlegame.
Common mistakes to avoid
Don't let e4 through for free: the opening's whole point is piece control of that square; if White achieves e4 without concessions, the b7-bishop bites on granite.
Don't fall asleep as Black: the setup is solid, but without a prepared ...c5 or ...d5 break White slowly squeezes with the extra space.
As White, don't swap the light-squared bishops carelessly: that trade usually eases Black's game, so keep the tension unless the exchange wins something concrete.
The main line, explained
3. Nf33.Nf3 sidesteps the Nimzo-Indian pin; the Queen's Indian is Black's matching reply.
3… b6...b6 announces the plan: the bishop will control the centre from b7 rather than occupy it with pawns.
4. g3g3 is White's main line: the bishop goes to g2 to neutralize b7 on the long diagonal.
4… Bb7...Bb7 completes the idea: together with the f6-knight, Black now controls e4 twice.
5… Be7...Be7 develops modestly; in this opening the dark-squared bishop plays a supporting role.
6… O-OBoth kings are safe. The middlegame revolves around whether White can achieve e4 or d5, and when Black frees the position with ...c5.
Frequently asked
What is the difference between the Queen's Indian and the Nimzo-Indian?
They are a repertoire pair: 3.Nc3 Bb4 is the Nimzo, 3.Nf3 b6 the Queen's Indian. The Nimzo fights for e4 with the pin, the QID with the b7-bishop; both are built on controlling e4 with pieces.
Should I play 4...Bb7 or 4...Ba6?
4...Ba6 is the modern main line, hitting c4 and forcing concessions, but it needs more theory. 4...Bb7 is the classical move and the best way to absorb the opening's core idea first.
Is the Queen's Indian too drawish?
It earned that reputation because elite players used it to neutralize 1.d4. At club level the positions are rich: whoever understands the e4 and d5 squares and times the pawn breaks better wins the game.
