Van Geet Opening Tubingen Gambit Puzzle (Rated 1638): Win Material — Hanging Piece Tactic

This Van Geet Opening puzzle is a classic middlegame example of tactical punishment for loose pieces. White has active pieces, strong central control, and a bishop that creates pressure along the kingside, while Black’s knight is overextended and vulnerable. The key idea is to notice when a defended-looking piece is actually hanging because of a pin, a discovered attack, or a forced exchange. In positions like this, the best move often wins material immediately and leaves the opponent’s king with lingering weaknesses.
