Learn How to Win with an Intermezzo: Endgame Tactics
This puzzle is a classic example of an intermezzo in a winning endgame-like middlegame: instead of recapturing immediately, the stronger side uses a forcing check to improve the position and keep the opponent under pressure. The key idea is that active pieces can outweigh raw material when the enemy king is exposed and key defenders are loose. In classical chess, these tactical pauses often decide whether a large advantage becomes decisive or slips away.
