Pawn Promotion Puzzle (Rated 505): Promote a Passed Pawn — Endgame

This chess endgame is all about converting an advanced pawn into a promotion threat before the opponent can organize counterplay. The key idea is that passed pawns become dramatically stronger when the king is active and the enemy king is too far away to stop them. In simplified positions, even a single tempo can decide whether the pawn queens or gets eliminated. Strong calculation and accurate king placement are essential in classical chess endgames like this.
