International Master Bryan Smith explains Nimzo Indian Defense strategies with real games. This hypermodern opening was developed by Grandmaster Aron Nimzowitsch who introduced it to master-level chess in the early 20th century. Unlike most Indian openings the NimzoIndian does not involve an immediate fianchetto, although Black often follows up with ...b6 and ...Bb7. By pinning White's knight Black prevents the threatened 4.e4 and seeks to inflict doubled pawns on White. White will attempt to create a pawn centre and develop his pieces to prepare for an assault on the Black position.
