Discovered Attack Puzzle (Rated 1399): Crush with a Passed Pawn — Endgame Tactic

This puzzle shows how a passed pawn can become the engine of a winning attack even in a material deficit. The key idea is to use the pawn as a forcing resource: it can open lines, create checks, and drag defenders away from the king. In practical classical chess, advanced pawns often work best when they also support a discovered attack or a direct strike on the enemy king. The position rewards calculation over material counting.
