Clemenz Opening Other Variations Puzzle (Rated 969): Win with a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of tactical punishment against an exposed king and loose pieces. Black uses a forcing queen check to drag the white king into a vulnerable square, then wins material by targeting an undefended bishop and the pawn behind it. The key idea is not a flashy mate, but a decisive material gain created by king safety problems, a trapped piece, and a skewer-like alignment that leaves White unable to coordinate defense.
