Learn How to Crush with Promotion: Decisive Material Gain
This puzzle is a classic example of how an advanced pawn can transform a position even when the board still looks like a middlegame. The key idea is that a passed pawn becomes a tactical weapon when it creates forcing threats, especially promotion threats that demand immediate attention. Here, the side to move uses a forcing check to drag the king and pieces into awkward squares, then converts the pressure into a decisive material gain. The combination relies on timing, not just raw material.
