Queen's Indian Defense Intermezzo in Chess

In the Queen’s Indian Defense Intermezzo, one side inserts a forcing “in-between” move before resolving the main tension of the opening. A typical defining feature is that the intermezzo is played at a moment when the opponent would otherwise get to capture, recapture, or complete a key setup (often involving …c5, …Nf6, or …Bb7). The point is to change the move order so the opponent’s intended sequence becomes less effective.
