NEW UPDATED OPENING LINE

[May 27, 2016] Updated Opening Line by GM Aleksandar Kovačević:
Nimzo-Indian Defense, Classical Variation with 4… O-O

[Line 180 : 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 O-O without 5. a3]

Line 180 deals with White’s various choices on the fifth move, except for 5. a3, which is covered in Lines 181-185.

After the fairly popular 5. Nf35… c5 is an independent line for Black, whereas most other moves transpose to some other lines.

6. dxc5 Na6 7. g3 Nxc5 8. Bg2 has become a modern tabiya and many theoretical discussions take place in this line. Black has two interesting choices that should be sufficient for equalization: 8… b6 and 8… Nce4.

Line 5. e4 is the most straightforward approach for the players of White, with lots of forced lines, like in the main 5… d5 6. e5 Ne4 7. Bd3 c5 8. Nge2.

[Diagram: White to Move] The diagrammed position is theoretically important for this line: White can get a long-term initiative, but great accuracy is needed!
