Nimzo-Indian Defense
Initial Moves: 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4
Strategic Summary & Main Idea
Developed by Aron Nimzowitsch, the Nimzo-Indian Defense (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4) pins the c3 knight and stops White from playing e4. Black seeks a firm positional grip on the central squares and often doubles White's pawns with ...Bxc3+.
Typical Plans for White
- The Rubinstein Variation with 4.e3, focused on solid development and the bishop pair
- The Classical Variation with 4.Qc2, avoiding doubled pawns on c3
- An attack with 4.f3 or 4.a3 to force the black bishop to decide
Typical Plans for Black
- Taking on c3 with ...Bxc3+ to double White's pawns, then hitting the weak c4 pawn with ...b6, ...Ba6 and ...Nc6
- Blocking the centre with ...d6 and ...e5, or counterattacking with ...c5
- Keeping absolute control of the e4 square
