Queens Pawn Game Sacrifice Intermediate Puzzle (Rated 858): Find Mate in 2 — Queenside Attack

This middlegame puzzle is a classic queenside attack with a forcing mating net. White’s active rook on the seventh rank and the exposed black king create a tactical race where material concerns matter less than coordination and tempo. The key idea is to use a sacrifice to drag a defender away, then finish with a direct queen invasion. In classical chess, these patterns often appear when one side’s pieces are overloaded and the king has limited flight squares.
