What Nimzo-Indian Defense puts on the board
Material is level, with white to move.
White has central pawns on d4.
White can still castle either side; Black can still castle either side.
What White is trying to build
Use the bishop pair when it is gained and decide how to manage doubled c-pawns.
Develop quickly enough that the centre cannot be attacked before it is supported.
How Black challenges it
Pressure e4 and control the centre with pieces.
Choose whether to damage White’s structure with …Bxc3 or preserve the bishop.
The tactical pattern to recognise
A pin on c3 can make e4 difficult to establish.
Doubled c-pawns can control central squares while leaving fixed targets.
What to check before committing
Treating doubled pawns as automatically bad instead of using their central control.
Giving up the dark-squared bishop without gaining structure or time.
