Learn How to Win Material: Zwischenzug Tactic
This middlegame puzzle is a classic intermezzo idea: instead of recapturing or simplifying immediately, one side inserts a forcing check that changes the order of moves. The key is that the checked king must respond first, and only then can the tactical follow-up win material cleanly. These positions often arise when a piece is hanging, a knight is overloaded, or a rook can exploit a loose target on an open file.
