Opening Puzzle (Rated 1263): Win Material — Skewer
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, the key idea is a tactical refutation: an apparently aggressive queen placement creates a direct opportunity to win material. The position rewards careful calculation because the attacking piece is itself vulnerable, and the correct sequence transforms the opponent’s threat into a decisive material advantage.
