Learn How to Win Material: Intermezzo Tactic
This puzzle is a classic example of a tactical intermezzo in a simplified middlegame/endgame setting. One side appears to be under pressure, but the real story is that a key defender is overloaded and the active pieces are lined up on the same file and diagonal. Instead of recapturing immediately or defending passively, the best move creates a forcing sequence that wins material by exploiting a skewer-like idea and a loose back-rank style alignment.
