Learn How to Skewer: Winning Material
This middlegame puzzle is built around a tactical refutation that turns an active queen into a winning material sequence. The key idea is a skewer: a valuable piece is forced to move, exposing a more valuable target behind it. In positions like this, the best move often comes from checking the king while also attacking a loose piece or rook. The result is not a mating attack, but a decisive material gain that simplifies into a clearly winning position.
