En Passant Puzzle (Rated 1338): Win with en Passant — Quiet Move

This chess endgame is a classic example of how a quiet move can decide everything. Even when material is down, the side to move can use king activity, pawn timing, and the threat of promotion to create a winning race. The key idea is not to rush into a direct capture, but to improve the position first and force the opponent into a losing pawn endgame. Patterns like en passant, zugzwang, and passed pawn races often decide these positions.
