The Queen's Indian Defense begins with one quiet pawn move that gives the c8-bishop two very different jobs. Learn when ...Bb7 should contest the center, when ...Ba6 should pressure c4, how ...Ne4 becomes an outpost, and which White setups remove Black's favorite pin before it appears.
Work through four Black blueprints and four White systems across the 4.g3 main line, ...Ba6, Kasparov, Petrosian, Miles, central d5, and the kingside pawn chase.

Verified source trail: every route is drawn from the Queen's Indian guide and its position bank. The five fixed tests produce e4 (+0.00), Bd2 (+0.38), ...Nxc3 (-0.16), ...Qg5 (-2.83), and Qxc3 (+4.40).
The 16 boards cover both bishop diagonals, the e4 outpost, Petrosian prevention, Miles development, d5 expansion, the Kasparov pawn chase, structural exchanges, and the tactical queen recovery. Every Learn route is tested twice.
