Learn How to Refute a Hanging Piece: Qb4+
This puzzle is a classic middlegame tactical refutation from the Queen’s Gambit Declined. Black’s active queen and knight coordinate against White’s exposed king and loose pieces, turning a material edge into a direct attack. The key idea is that forcing moves can override static material: a check, a capture, and a follow-up tactic can collapse White’s position before development or king safety matters. In classical chess, these short combinations often decide the game immediately.
