Nimzo-Indian Defense
The Nimzo-Indian is one of the most respected defenses to 1.d4. Black pins the knight, fights for e4, and often hands White doubled pawns to argue about for forty moves.

Give White the center, then blow it up. It is one of the sharpest ways to meet 1.d4.
Queen's Gambit
One of the oldest openings in chess, mentioned in the Göttingen manuscript of 1490 and still played at the top level today. The Slav and the Semi-Slav both grow out of its first moves.

Think of it as the Queen's Gambit Declined without the bad bishop. It is one of the most solid answers to 1.d4.
Why the pin matters
White's knight on c3 is the main defender of the e4 square. By pinning it with ...Bb4, Black stops e2-e4 in its tracks and fights for the center with pieces rather than pawns. That is the core hypermodern idea, and Nimzowitsch built a system around it.
If White breaks the pin with a3, Black takes on c3 and White recaptures with the b-pawn. The resulting doubled c-pawns shape many Nimzo-Indian middlegames: White has the bishop pair and a big center, Black has the better structure and a plan (blockade c4, put a knight on a5 or e4, and target the doubled pawns).
What each White fourth move is trying to do
- 4.e3 (Rubinstein): a flexible main line. White develops with Bd3 and Nf3 or Ne2, and leaves it to Black whether to take on c3 and double the pawns.
- 4.Qc2 (Classical): White prepares to recapture on c3 with the queen and avoid doubled pawns entirely, at the cost of time. It is now as popular as 4.e3, and on Lichess it is the most played fourth move above 2000.
- 4.a3 (Samisch): White forces the trade at once and plays for the bishop pair and a big center with f3 and e4.
- 4.Nf3: White waits to see Black's reply. 4...d5 transposes to the Ragozin, and 4...b6 leads to positions close to the Queen's Indian.
The whole opening is one long argument: are the two bishops and the big center worth more than the doubled pawns? Much depends on whether White can play e4 and open the position. While the center stays blocked, the doubled pawns are a lasting weakness; once it opens, the bishops come into their own.
Typical Black plans
- Blockade c4 with a knight on a5 or with ...b6 and ...Ba6, hitting the pawn directly.
- Plant a knight on e4, backed by ...d5 and ...f5 in a Dutch-style setup.
- Play ...c5, then ...d6 and ...e5 as in the Hübner Variation, to blockade the center and keep the doubled pawns as long-term targets.
Frequently asked questions
Why is the Nimzo-Indian so highly regarded?
It is theoretically sound, and the positions reward understanding more than memorization. On Lichess, Black scores about 50% with 3...Bb4 at every rating level, slightly more than with 3...d5. Every world champion since Capablanca has played it, and 3.Nf3 is popular for White largely as a way to avoid it.
What happens if White avoids the Nimzo with 3.Nf3?
Then ...Bb4 is not available with the same effect, so Nimzo players need a second defense: usually the Queen's Indian (3...b6), the Bogo-Indian (3...Bb4+) or the Ragozin/QGD (3...d5). Prepare the two together, because you will meet 3.Nf3 often. On Lichess it follows 2...e6 in over a third of games at 2200+, and in under a fifth below 2000.
