Post Mortem Puzzle (Rated 1577): Win with a Skewer — Decisive Chess Puzzle with Theory & Hints

This puzzle is a classic middlegame tactical win built around a skewer on the seventh rank. White’s active rook and knight coordination create immediate pressure against the black king and loose pieces, while Black’s king shelter is weakened and several pawns are vulnerable. The key idea is to force the defender into awkward squares, then use checks and discovered threats to overload the position. Once the defensive pieces are displaced, the attack becomes decisive.
