Zwischenzug (Intermezzo): The Surprise Weapon in Your Chess Arsenal

"When you see a good move, look for a better one." - Emanuel Lasker

 
Zwischenzug Chess Resources

Have you ever been outmaneuvered in chess, feeling like your opponent pulled a rabbit out of a hat?

That surprise move might have been a Zwischenzug (pronounced "tvee-SHEN-tsoog"), also known as intermezzo, a powerful chess tactic that throws a curveball into your opponent's plans.

  Instead of making the expected move, like capturing a piece, a Zwischenzug inserts an unexpected move that creates a new threat or disrupts your strategy. Mastering this tactic will transform you from a predictable player to a cunning strategist, allowing you to exploit unexpected opportunities and gain a significant advantage.

 With explanations and examples

German "in-between move". An unexpected move tossed into an expected series of moves.
