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''.

The diagram shows an example. It is Black's turn to move and Black moves
: '1. ... Rxh4'
expecting White to play 2. Qxh4, when Black retains a material advantage. However, White has a zwischenzug:
: '2. Qd8+'
which is followed by
: '2. ... Kh7'
: '3. Qxh4+ Kg8'
: '4. Qxg3'
and White has won a rook, leaving him with a winning position.
Another example occurred in Tartakower-Capablanca, New York 1924,[1] which Irving Chernev christened "the Immortal Zwischenzug Game." In the position at right, Tartakower (White) has just played 9. Bxb8, thinking he has caught Capablanca in a trap: if 9...Rxb8, 10.Qa4+ and 11.Qxb4 wins a bishop. However, Capablanca sprang the zwischenzug 9...Nd5!, protecting his bishop and also threatening 10...Ne3+, forking White's king and queen. After Tartakower's 10.Kf2 Rxb8, Capablanca had regained his piece and went on to win in 20 more moves. Note that after 10.Bf4 (instead of 10.Kf2), Black would not play 10...Nxf4??, which would still allow 11.Qa4+, winning a piece. Instead, after 10.Bf4 Black would play a second zwischenzug, 10...Qf6!, attacking the bishop again, and also renewing the threat of 11...Ne3+. After a move like 11.Qc1, Black could then either take the bishop or consider still a further zwischenzug with 11...Bd6 or 11...g5.
