Pseudo Queen's Indian Defense

The full Queen's Indian setup (knight to f6, pawn to b6, bishop bound for b7) offered to a White player who has not yet said c4.

The pseudo in the name is a librarian's word, not a criticism. In the true Queen's Indian White has committed a pawn to c4; here White chose 2. Nf3, so Black's 2...b6 is both a standing invitation to transpose. One c4 and you are in the real thing. It is also a complete system if White declines. The bishop's job on b7 does not change either way: watch the long diagonal, restrain e4, and turn White's central expansion into a negotiation instead of a right.

The ...b6 fianchetto against the queen's pawn is Aron Nimzowitsch's legacy: control the center with pieces first, occupy it later, and let an overextended opponent walk into the pressure. What this move order concedes is that White picks the battlefield, and most club players pick their pet system. The London bishop to f4, the Torre pin with Bg5, a kingside fianchetto, or plain e3 development. None of these refutes anything. The real contest is whose setup knowledge runs deeper, which is why scheme-based players live here happily from both sides.

One structural note is worth carrying into every game: the g3 plans, where White fights for the very diagonal Black just claimed, are the most principled test. When both light-squared bishops aim at the center, the fight turns on the d5 and e4 squares, and the timing of ...c5 or ...d5 decides whether Black frees the position or just creates targets. Meet the system moves with development and a plan of your own, and this opening will never ambush you.
