Zugzwang Puzzle (Rated 1103): Win a Chess Endgame — Pawn Promotion

This chess endgame is a classic example of converting a small edge with precision. The key idea is to use king activity, create a passed pawn, and force the defender into a losing pawn structure. In positions like this, the strongest move is often not a direct check or capture, but a quiet move that improves the king’s placement and sets up a promotion race. The side to move must calculate far ahead because one tempo can decide everything.
