The Nimzo-Indian Defense

The Nimzo-Indian Defense is an opening in chess that begins with the moves 1.d4 Nf6 2.c4 e6. Black allows White to establish an apparently strong center with pawns on c4 and d4 but then undermines it immediately with ...e6 and ...c5. Black's light-squared bishop develops actively on b7, eyeing the long diagonal. The Nimzo-Indian Defense leads to complex positions with chances for both sides to attack. White must find ways to defend the center and counterattack against Black's aggressive setup. Although Black concedes space in the center, active piece play provides good chances to generate counterplay. The Nimzo-Indian Defense is a dynamic and popular opening at all levels of chess.
