Passed Pawn Puzzle (Rated 1091): Skewer — Win Material

A skewer is a powerful tactical pattern in which a valuable piece is attacked first, forcing it to move and exposing a less valuable piece behind it. In this middlegame position, Black can exploit an aligned queen and rook on an open file. The key idea is to recognize that the attacked queen is not simply retreating: its movement uncovers a direct attack on the rook behind it. This tactical refutation overturns White’s material advantage and leads to a clearly winning position.
