Learn How to Use an Intermezzo: Crushing Tactical Refutation
This puzzle is a classic middlegame tactical refutation from the Catalan Opening. White’s active queen and rook coordination create a forcing sequence that wins material by exploiting a pinned queen and an overloaded defender. The key idea is an intermezzo: instead of recapturing immediately, White inserts a forcing check that changes the order of operations and leaves Black unable to keep everything defended. These are the kinds of positions where activity matters more than static material.
