What is zwischenzug in chess?

In the world of chess, there is a vast array of tactics and maneuvers that players employ to gain an advantage over their opponents. One such tactic that often leaves opponents perplexed is the “zwischenzug.”

In this article, we will explore what zwischenzug is in chess, its tactical significance, and how mastering this in-between move can make you a more formidable chess player.

Definition of Zwischenzug

The term “zwischenzug” has its origins in the German language, where “zwischen” means “in between,” and “zug” translates to “move.” Hence, “zwischenzug” quite literally means an “in-between move” in chess. It’s a move that disrupts the expected sequence of moves in a chess game.

  • The Concept of an In-Between Move

Imagine a typical chess position where you and your opponent are taking turns making moves. A zwischenzug is a surprise move inserted in the middle of this sequence, breaking the anticipated flow. This unanticipated move can catch your opponent off guard and disrupt their plans, as they must now respond to this unexpected in-between move.

Examples of Zwischenzug

To understand the concept better, let’s delve into some examples of real-game situations where zwischenzug plays a crucial role:

  • Interfering with Castling: A classic zwischenzug involves an unexpected check or threat in the middle of an opponent’s castling maneuver. This forces the opponent to address the immediate threat rather than continuing with their castling plans.
  • Interrupting a Threat: If your opponent has a piece threatening one of your valuable pieces, you can employ a zwischenzug to interpose an in-between move. This could be a counter-attack or a piece exchange, forcing your opponent to reconsider their strategy.
  • Material Gain: Sometimes, an in-between move can lead to material gains. For instance, an unexpected zwischenzug can put your opponent’s pieces in vulnerable positions, allowing you to capture a piece with a tactical advantage.

Mastering Zwischenzug

To become proficient at using zwischenzug in your chess games, consider the following strategies:

  1. Anticipate Opponent’s Moves: Try to predict your opponent’s plans and identify moments where zwischenzug can be most effective.
  2. Practice, Practice, Practice: Regularly solve chess puzzles and practice situations involving zwischenzug to improve your ability to spot these tactical opportunities.
  3. Study Grandmaster Games: Learning from the experts is an excellent way to master zwischenzug. Analyze grandmaster games to see how they effectively use in-between moves to outmaneuver their opponents.
  4. Use Chess Software: Utilize chess software and engines to analyze your games. These tools can help identify tactical opportunities, including zwischenzug, that you might have missed during your games.


Zwischenzug, the in-between move in chess, is a potent tactical weapon in the hands of a skilled player. It disrupts your opponent’s plans, creates new tactical opportunities, and can lead to material gains. By mastering zwischenzug, you can become a more formidable chess player and surprise your opponents with your tactical prowess.

Remember, practice and study are key to improving your zwischenzug skills, and they can make you a force to be reckoned with in the world of chess. So, the next time you’re on the chessboard, don’t hesitate to seize the moment with a well-executed zwischenzug.
