1.d4 Nf6 2.c4 e6 3.Nc3 Bb4
What is the Defensa Nimzo-India?
La Nimzo-India (1.d4 Cf6 2.c4 e6 3.Cc3 Ab4) clava inmediatamente el caballo de c3 y amenaza desequilibrios estructurales precisos (Axc3 crea peones doblados en c3 para las blancas). Inventada por Aron Nimzowitsch, es la defensa favorita de la élite desde hace un siglo: Botvinnik, Karpov, Kasparov, Caruana. Planes ricos, teoría profunda pero prioridad a la comprensión: las negras cambian su alfil de casillas negras por el caballo de c3 para romper el centro blanco y usan la actividad de las piezas para compensar.

Frequently asked questions
Why is the Nimzo-Indian so respected?
It directly addresses 1.d4's strategic goals. By pinning the c3 knight, Black prevents e4 and hypermodern-izes the position. Whether Black keeps the bishop pair or trades it for doubled pawns, the strategic battle favors Black's long-term chances.
Should Black play Bxc3 or keep the bishop?
Depends on the line. In 4.a3, Black has no choice, 4...Bxc3+ is forced. In 4.Qc2 or 4.e3, Black can keep the bishop and develop normally. Modern theory often favors Bxc3 only when it doubles White's pawns.
Is the Nimzo good for beginners?
No, the theoretical complexity is high and the strategic nuances (when to give up the bishop pair, when to challenge the center with ...c5 or ...d5) require experience. Beginners should play the QGD or Slav first.
Who plays the Nimzo-Indian at the top level?
Almost every elite player, Karpov, Kasparov, Kramnik, Anand, Carlsen, Caruana. The Nimzo is considered one of Black's most theoretically sound defenses against 1.d4. A lifetime choice for many world champions.
How does the Nimzo compare to the King's Indian?
The Nimzo is more strategic and positional; the King's Indian is sharper and more tactical. Nimzo = piece play and doubled-pawn strategy. KID = opposite-wing attacks and kingside storms. Both are top-tier elite defenses.
