Hanging Piece Puzzle (Rated 1418): Win a Chess Endgame — Pawn Promotion

This puzzle is a classic chess endgame and middlegame transition where material, activity, and promotion threats collide. White must balance a hanging piece against a dangerous passed pawn race, and the key idea is that tactical gains can outweigh static material deficits. In positions like this, the side with the more advanced passer often gets the initiative, especially when the enemy queen or rook is overloaded and cannot defend everything at once.
