Nimzo-Indian Attack Defender Chess Puzzles

The Nimzo-Indian Attack Defender is a defensive motif in the Nimzo-Indian family that helps Black meet White’s early pressure after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4. Its defining feature is the bishop pin on c3, often combined with ...d5 or ...c5 to challenge White’s center before the attack gains momentum.
