Van Geet Opening Grunfeld Defense Puzzle (Rated 1359): Win Material — Tactical Refutation

This opening puzzle shows how a single active piece can create a decisive tactical refutation. White’s advanced knight and bishop coordinate against Black’s king-side structure, while the black queen and knight become overloaded by the pressure on key central squares. In classical chess, these positions often reward forcing play over slow development, because one accurate capture can collapse the opponent’s coordination and win material immediately.
