About the Nimzowitsch Defense
Black answers 1.e4 with 1...Nc6, an offbeat move that blocks the c-pawn. Black hopes to reach a French- or e5-type game on their own terms.
After 2.d4, Black often plays ...d5 or ...e5 to hit the centre.
The c6 knight blocks ...c5, so Black uses piece pressure on d4 instead.
White can simply grab space with d4 and d5; Black must play actively.
