Pawn Promotion Puzzle (Rated 1564): Spot Pawn Promotion — Mate in 2

This puzzle is a classic example of how a far-advanced passed pawn can override material. Even when one side appears to be winning, a single tactical resource on the queenside can force the king into a mating net. The key idea is that promotion threats are not always about winning a queen outright; sometimes the new queen is only a temporary piece that supports a forced finish. In chess endgame positions like this, calculation matters more than static evaluation.
