Learn How to Win with an Intermezzo: Hanging Piece
This puzzle is a classic example of a forcing intermezzo in a sharp middlegame-to-endgame transition. Instead of recapturing immediately, the stronger side uses a checking move to create a new threat and exploit loose pieces. The key idea is that hanging pieces and king safety can outweigh raw material, especially when the enemy king is exposed and coordination is poor. In practical chess endgame play, forcing moves often decide everything before the position can simplify.
