Classical Variation
The Classical Variation with 4.Qc2 is the most popular and flexible approach to the Nimzo-Indian Defense. By developing the queen to c2, White supports the knight on c3 while maintaining all options for future development. This leads to rich strategic battles with excellent practical chances for both sides.

Why 4.Qc2?
The queen on c2 serves multiple purposes: it supports the knight on c3, allows for flexible development, and maintains pressure on the center. Unlike other moves, Qc2 doesn't commit White to any specific pawn structure, preserving maximum flexibility for the middlegame.
Black's Strategic Options
Main Defensive Ideas
- Exchange timing: Choose when to trade the bishop on c3
- Central breaks: ...c5 or ...d5 for active counterplay
- Piece activity: Develop pieces actively before committing to exchanges
- King safety: Castle early to secure the king position
- Queenside play: Create counterplay on the queenside
Typical Plans for White
Central Dominance
Establish a strong pawn center and use it as a foundation for attack.
Kingside Development
Complete development harmoniously and maintain piece coordination.
Positional Pressure
Build long-term positional advantages through superior piece coordination.
Key Strategic Points
For White: Don't rush to trade the knight. Maintain flexibility and look for the optimal moment to advance e4.
For Black: Time the bishop exchange carefully. Create counterplay before White establishes full central control.
Modern Theory
