Zwischenzug is german for intermediate move. It's one of those super useful techniques to have in one's chess arsenal. In a sequence of moves, instead of playing the expected move, a player will first play another (unexpected) move or moves and only then play the expected move. This will benefit the player who does the zwischenzug. The most common type of zwischenzug, or intermediate move, comes in the form of an intermediate check (zwischenschach), but not necessarily so. This might all seem very complicated, so let's look at some concrete and very instructive examples here below.
