D4 Openings For Black Puzzle (Rated 1586): Skewer — Exposed King
A skewer is a tactical attack on a valuable piece that forces it to move, exposing a less valuable piece behind it. In this middlegame puzzle, Black exploits the alignment of White’s bishop, pawn, and rook to create a decisive material gain. The exposed king and active rook make the tactic especially powerful: once the first target is displaced, the second target becomes vulnerable along the opened file.
