About this variation

White plays 4. e3, developing calmly and preparing Bd3 and Nge2. It is one of the main lines of the Nimzo-Indian.

The Rubinstein System is 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3. Named after Akiba Rubinstein, it is one of White's most solid answers to the Nimzo-Indian. White develops calmly with Bd3 and Nf3 or Nge2, castles and keeps the option of a3 to ask the bishop on b4 to decide whether to take on c3.

Black has several main systems. The line with ...O-O, ...d5 and ...c5 leads to positions with an isolated queen's pawn or hanging pawns after exchanges in the center. The Hübner Variation with ...c5, ...Bxc3+ and ...d6 sets up a dark-square pawn chain that blunts White's bishop pair. Lines with ...b6 and ...Bb7 combine the Nimzo-Indian with Queen's Indian ideas.

White's plans depend on the structure. With an isolated queen's pawn, White aims for active pieces and a kingside attack. With doubled c-pawns after ...Bxc3, White wants to open the position for the bishop pair, often with e4 or f3 and e4. With Nge2, White avoids doubled pawns by recapturing on c3 with the knight.

Black's typical ideas include trading the bishop for the c3 knight to inflict doubled pawns, blocking the center with dark-square pawns, and using the light squares. Black should be careful not to give up the bishop without a clear reason, since White's bishop pair can become strong in an open position.

The Rubinstein System suits White players who want a reliable, flexible system with many middlegame plans. It is a good choice for learning classical pawn structures such as the isolated queen's pawn and hanging pawns, which appear across many other openings.

Black players should prepare at least two of these systems, since White's choice between Bd3 and Nge2 changes the character of the game a lot.

It is one of the main lines of the Nimzo-Indian Defense.
