Nimzo-Indian Intermediate Move Chess Puzzles

A Nimzo-Indian Intermediate Move is a forcing in-between move inserted during a Nimzo-Indian Defense sequence, usually before recapturing or completing development. In this opening, it often appears after White plays 4.Nf3 or 4.e3 and Black has already pinned the knight with ...Bb4, using a check, threat, or tactical shot to change the move order. For an intermediate player, the key idea is that the extra move is not random: it exploits the pin on the c3-knight or the tension around the center to gain a tempo.
