Hans Niemann (Black) Puzzle: Outflank — Pawn Endgame

This chess endgame is a pure king-and-pawn battle where timing matters more than material. Both kings are active, and each side has dangerous passed pawns supported by a flexible pawn structure. The key strategic idea is to create a pawn breakthrough while forcing the opposing king into an unfavorable response. Once the kings become tied to opposing pawns, a single tempo can determine whether a passer advances, gets exchanged, or reaches promotion.
