The Nimzo-Indian Defence: 1.d4 Nf6 2.c4... 4.Qc2 arises after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 and falls under ECO code E32. The Classical Variation, 4.Qc2, aims to address two main problems posed by the Nimzo-Indian defence. On c2 the white queen protects the knight on c3, meaning that Black will no longer be able to double White's pawns by exchanging bishop for knight. At the same time, the queen hits the important e4 square. A note on strategy and rules of thumb: Beginning chess players are often told not to move the queen too early in the opening. While as a general rule this advice is valuable, it is not sacrosanct. The Classical Nimzo provides an excellent opportunity to examine this rule, and its limitations, more closely. The admonition against early queen moves stems partly from the fact that the opposing player may be able to harass the queen simply by making useful developing moves. While one player is struggling to return his queen to safety, the second is gaining a decisive lead in development. In the Classical Variation, however, the queen's deployment to c2 is hardly a brazen sortie into enemy territory. It is unlikely that Black will be able to easily attack the queen anytime soon, so White's move is not considered risky. A second reason to delay the queen's development is that the queen does not work well without the assistance of the minor pieces, and it is not clear until the knights and bishops are deployed where the queen will be most useful. With 4.Qc2, it is true that White neglects to develop a kingside piece or even to open lines for development, but it is clear that the queen will perform a useful function on c2. The fight for the e4 square is always a significant theme in Nimzo-Indian games, and the queen contributes to this fight. She also bolsters White's position on the queenside by protecting the pawn structure, and at the same time she takes aim at Black's kingside. White should not have a problem deploying the queen from c2 to whatever theater of battle requires her services. With 28,005 games in the master database, it is a well-established opening choice.

Common Mistakes to Avoid
- Neglecting development: In the Nimzo-Indian Defence: 1.d4 Nf6 2.c4... 4.Qc2, it can be tempting to make extra pawn moves early on. However, falling behind in development can be punished quickly, especially in open positions where opponent pieces can find active squares.
- Allowing White to build an overwhelming center: Hypermodern openings allow White space in the center, but you need to strike back at the right moment. Delaying the counterattack too long can leave you without active play.
- Playing without a plan: Each position in the Nimzo-Indian Defence: 1.d4 Nf6 2.c4... 4.Qc2 demands a specific approach. Understand whether you should be attacking, defending, or maneuvering before making your move. Random moves lead to random results.
- Forgetting about piece coordination: Chess pieces are strongest when they work together. A single piece attacking alone is easy to defend against, but coordinated pieces can create unstoppable threats.
