Zwischenzug

The zwischenzug (German for "intermediate move", IPA: ) is a common chess tactic in which a player, instead of playing the expected move (commonly a recapture of a piece that the opponent has just captured) first interpolates another move, posing an immediate threat that the opponent must answer, then plays the expected move. Ideally, the zwischenzug changes the situation to the player's advantage. Such a move is also called an intermezzo, intermediate move, or in-between move.
