[May 18, 2017] Updated Opening Line by Bojan Vučković:
Nimzo-Indian Defense, Rubinstein Variation (incl. Taimanov & Keres Variations)

[Line 186 : 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 without 4… c5, 4… O-O]

The most frequent choice of the players of Black against this classical setup is 4… O-O, and it is covered in our Lines 189-194, while the other popular option 4… c5 can be found in Lines 187-188.

Move 4… b6 is also seen quite often in grandmaster practice. If White opts for 5. Nge2 Black has Fischer (5… Ba6), Romanishin-Psakhis (5… c5) and American Variations (5… Ne4) at his disposal. In case of 5. Nf3 the game usually continues with 5… Bb7 6. Bd3 O-O 7. O-O, where apart from the transposition to our Line 191 with 7… d5, Black also has a perfectly fine alternative in the Keres Variation (7… c5).

Taimanov Variation (4… Nc6) is a less investigated possibility since White is here typically able to obtain a small advantage. For example 5. Bd3 e5 6. Nge2 d5 7. cxd5 Nxd5 8. e4 Nb6 9. d5, and White has more space for his pieces.
