Blackmar Diemer Gambit Middlegame Puzzle (Rated 1302): Spot It — Hanging Piece

A hanging piece is an undefended or insufficiently protected unit that can be captured without adequate compensation. In this middlegame, material is temporarily imbalanced, but White’s active rook and pressure against the centralized king create a tactical opportunity. The key idea is to recognize that a loose knight is more important than the immediate attack on White’s queen. A precise tactical refutation changes the material balance and leaves White with a decisive advantage.
