Queens Gambit Accepted Showalter Variation Puzzle (Rated 1429): Win with a Quiet Move — Endgame Skewer

This chess endgame is a classic example of using rook activity to create a decisive tactical gain. White’s pieces are far more active, with the rook invading the seventh rank and the bishop supporting key squares. The key idea is not a flashy sacrifice, but a quiet move that improves coordination and sets up a skewer against the enemy king and rook. In classical chess, these small tempi often decide the game when one side’s pieces are tied down.
