Nimzo-Indian Defense: Pin the Knight
The Nimzo-Indian Defense starts with 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4. Black's bishop move immediately pins your knight to your king, forcing you to respond carefully. This opening teaches you how to contest the center while your pieces develop.
The Opening Setup
d4 and c4 occupy and control the center, while Nf6 develops Black's knight and controls key central squares (e4 and d5). When you play Nc3, your knight also controls e4 and d5, adding pressure to Black's position. Then Black strikes with Bb4, pinning your knight against your king. This pin is Black's main idea: it restricts your pieces and makes you plan carefully.
Black's Strategic Goal
Black's plan is to contest the center before you occupy it completely. The bishop on b4 isn't just pinning—it's also developed to an active square. While Black develops with tempo (forcing you to respond to the pin), Black is fighting for control of the key central squares: d5 and e4. Your knight on c3 controls both, but Black's move on e6 also pressures d5, so the center remains contested and tense.
White's Plan
Your goal is to occupy the center, develop quickly, castle to safety, then pick a wing to attack. The pin on c3 slows your coordination, but once you develop your other pieces and castle, you can execute your plan. The key is not to panic: you have plenty of central control between d4, c4, and your knights on c3 and (soon) f3. Stay calm, develop, castle, and you'll have good play.
