NEW UPDATED OPENING LINE

[October 18, 2016] Updated Opening Line by GM Vadim Zvjaginsev:
Nimzo-Indian Defense, Classical Variation (Milner-Barry, Old Zuerich, Noa & San Remo Variations) 

[Line 175 : 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 without 4… c5, 4… O-O]

Move 4… O-O is covered in our Lines 180-185, while 4… c5 can be found in Lines 178-179.

The main topic of this opening line is the the Noa Variation (4… d5), where move 5. cxd5 is the subject of Lines 176-177. In the critical position, which occurs after 5. a3 Bxc3+ 6. Qxc3 dxc4 7. Qxc4 b6, Black should have a reasonably satisfactory play.

On the other hand, we consider the San Remo Variation (4… d5 5. a3 Bxc3+ 6. Qxc3 Ne4 7. Qc2 Nc6 8. e3) dangerous for Black, after 8… e5 9. f3!.

In the Milner-Barry Variation (4… Nc6 5. Nf3 d6) White should be able to secure a slight advantage after 6. Bd2 O-O 7. a3 Bxc3 8. Bxc3, thanks to his bishop pair.
