Fork Puzzle (Rated 2275): Skewer — Rook Tactic
A skewer attacks a valuable piece in front of a second target, forcing the first target to move and exposing the piece behind it. In this middlegame, the king and rook are aligned so a forcing rook check creates a double threat. Black’s rook near the white king also pins and traps a bishop, making the position tactically urgent. The key idea is to use checks to reverse the pressure and exploit the overloaded defensive setup.
