Learn How to Win with an Intermezzo: Endgame Tactics
This puzzle is a classic chess endgame tactic built around an intermezzo: a forcing check that changes the move order and wins material. Instead of grabbing the obvious target immediately, White first uses the rook to create a decisive tempo, forcing the king to respond. That small pause is enough to expose the defender and make the final capture work cleanly. In practical classical chess, these in-between moves often decide otherwise balanced positions.
