Van Geet Opening Dunst Perrenet Gambit Puzzle (Rated 1002): Win Material — Discovered Attack

This middlegame puzzle shows how a well-timed sacrifice can open lines against the enemy king and create a decisive material gain. White’s active bishop and queen coordinate to exploit weak dark squares around the kingside, while Black’s pieces are awkwardly placed and the king’s shelter is vulnerable. The key idea is to force the defender away, then use the resulting discovered attack to win major material with tempo and initiative.
