Nimzo-Indian Defense


Supposedly, the Nimzo-Indian Defense is best for black when white opens d4.  What is the winning percentage of Nimzo-Indian?  Is there a statisically better defense against d4?


Statistics are interesting, but a poor way to choose an opening.  The first consideration is whether the defense suits your personal style.  Some players are most at home in a Nimzoindian, while others prefer the King's Indian.  They are completely different, but each is good for the players whose styles match up.

You should first have a grounding in the Queen's Gambit - Accepted, Declined Orthodox, Slav Defense, and perhaps even the Tarrasch (a chess education in itself) before venturing into the Indian Defenses.
