The most popular master moves:
- 4. e3 Normal line
- 4. Qc2 Classical variation
Let's play a Nimzo Indian
Sort:
Ok, e3 played, black to move.
Well, I'd suggest to make the most popular moves when they are confirmed by engine evaluations. 
It's 4...O-O here.
In a position like this, I always feel castling is too early. What about d5?

All right. If U don't wanna castle, there are 3 good options:
- 4...c5 Huebner variation (6745 master games, ev=+0.2, sev=+0.30, sh2=0.63)
- 4...b6 St. Petersburg variation (4107 master games, ev=+0.1, sev=+0.20, sh2=0.82)
- 4...d5 (962 master games, ev=+0.1, sev=+0.32, sh2=0.65)
N.B. sev = statistical evaluation (chesstempo, 2200+ vs 2200+); sh2 = statistical black sharpness.
According to these data 
, I'd suggest St. Petersburg 4...b6 having good evaluations and the good sharpness too.

One of my old OTB tournament games:
I can't find any vote chess or themed tournaments to join, so here's a Nimzo Indian to get things started.
Black to move.
