Chess Opening Theory/1. d4/1...Nf6/2. b4

The Neo-Polish Variation is an variation of the Indian Defense in which White commits to a push of a flank pawn instead of a center pawn. This move is not seen much in the top level because it does not benefit White in most ways. As, Black will try to play e6 and attack the pawn or play g6 into a King's Indian type of setup, it is recommended that White plays very carefully and tries to play moves like Bb2 and a3, just like if they had played b4 on the first move.
