David And Goliath Mate Puzzle (Rated 1500): Spot David-and-Goliath Mate — Mate in 1

This puzzle is a classic David-and-Goliath mate: a small, advanced pawn delivers the final blow while the heavier pieces on the board are helpless to stop it. The key idea is that king safety matters more than material count when the enemy king has no escape squares and your pieces already control the surrounding lines. Even in a middlegame, a single forcing move can end the game immediately if the king is boxed in.
