Learn How to Win a Hanging Piece: Endgame Refutation
This chess endgame puzzle is about spotting a hanging piece and turning it into a tactical refutation. The key idea is that an active rook can often win material when an enemy knight is left undefended and the position is already simplified. Here, the side to move has a forcing way to remove the loose piece and then exploit the resulting weaknesses with a check that keeps the opponent under pressure. In classical chess, these small tactical details often decide the game.
