Learn How to Win with a Skewer: Middlegame Tactics
This puzzle is a classic middlegame tactics lesson built around a skewer on an open file, with extra pressure from overloaded defenders and a forcing sequence that wins material. The key idea is that one tactical shot can expose several loose pieces at once: a pinned rook, a vulnerable queen, and a king that cannot comfortably step away. In practical classical chess, these patterns often decide the game before any endgame technique is needed.
