Zwischenzug in chess
The expected recapture can wait. Insert a check or a bigger threat first, and the whole exchange changes value.
A zwischenzug (German for "in-between move", also called an intermezzo) is a move played instead of the expected recapture or reply. It creates a threat that the opponent has to answer first.
Why it works
Exchanges have a rhythm: one side captures, the other takes back. A zwischenzug breaks that rhythm. Instead of recapturing at once, you play a move with a bigger threat, such as a check, an attack on the queen or a mate threat. The opponent has to deal with it, and only then do you make the recapture you were "supposed" to make.
The result is a free tempo, and sometimes a whole piece. An exchange that looked even can become a winning one purely because of the move order.
Recapturing automatically is a common mistake in club chess. Before you take back, ask once: is there a check, a capture or a threat that is even bigger?
How to spot one
- Look at the position after the opponent's capture but before your recapture. What is suddenly loose or exposed on their side?
- Scan checks first. A check is the most forcing zwischenzug because it cannot be ignored.
- Watch for the enemy queen or king appearing on a line your pieces already control.
- In calculation, whenever a line ends in "and then I take back", test one alternative first.
Zwischenzug in defense
It works both ways. When you are the one about to lose material, an in-between check or counter-threat can save the position. Your opponent has to answer it first, and a move later the tactic they were counting on may no longer work.

Related tactics
Fork
One piece, two targets. On Lichess, more puzzles turn on the fork than on any other motif, over twice as many as on the pin. It is the first tactic worth mastering.
Discovered attack
Move one piece and a different piece behind it makes the threat. The piece that moved can make a threat of its own, so one move often creates two attacks.
Deflection
A piece is doing an important job. Give it something it cannot refuse, and the job goes undone.
Frequently asked questions
What is a zwischenzug?
An in-between move: instead of making the expected reply (usually a recapture), you play a move carrying a bigger threat. The opponent must respond to it, and you then make the original move under better circumstances.
What is the difference between zwischenzug and intermezzo?
None. They are two names for the same idea, one from German and one from Italian. English-language chess writing uses both interchangeably, along with "in-between move" and "intermediate move".
