Queens Gambit Accepted Saduleto Variation Mate In 1 Beginner Puzzle (Rated 886): Spot Mate in 1 — Rook Tactics

This middlegame puzzle is a classic example of a forcing tactical finish built around an active rook and a vulnerable back rank. White’s pieces are coordinated well enough to create a direct mating net, and the key idea is that a seemingly ordinary rook move can become decisive when the enemy king has no safe squares and no useful interposition. The position also shows how a hanging piece can be ignored when the attack is immediate.
