Why play the Nimzo Indian?
1. Only need to learn system opening against 1.d4
Same opening strategy works against Catalan
If you instead play Queen’s Indian or Queen’s Gambit Declined ...
You need to study another line to play against Catalan
2. Nimzo Indian Can Be Incredibly Dangerous for White
Since it gives asymmetric position with edges
3. Don’t need to memorize opening, just understand concepts
