Van Geet Opening Novosibirsk Variation Puzzle (Rated 1577): Win Material — Trapped Piece

This middlegame puzzle is about turning active piece placement into a decisive material win. White’s queen and rook coordination create a powerful tactical net, while Black’s king remains exposed in the center. The key idea is a classic skewer: once the heavy piece lands on the open file, the queen is forced into a vulnerable line and the follow-up wins material. In classical chess, these patterns often decide master vs master games because one loose piece can collapse the whole position.
