Nimzo-Indian Defence
MICOS Opening Group E12.NI – Nimzo-Indian Defence begins with 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4. Black develops the bishop actively to b4, pinning White’s knight and increasing pressure on the centre without immediately committing to a fixed central pawn structure. This flexible approach gives Black several ways to respond to White’s development while maintaining active piece play.
The Nimzo-Indian Defence can produce strategically rich positions where pawn structure, control of key central squares and piece activity strongly influence the plans for both sides. Black can choose between solid positional play and more dynamic counterplay, making flexibility one of the opening’s defining characteristics.
