Openings Against D4 Puzzle (Rated 1173): Win — Hanging Piece
A hanging piece can completely change the evaluation of a middlegame. In this Queen's Gambit Declined position, Black must recognize that White's active pieces have created tactical pressure, but one white bishop is insufficiently protected. The key idea is to calculate forcing captures before responding to the apparent threats. By exploiting the loose piece and the exposed white king, Black converts a material deficit into a decisive advantage while preserving dangerous attacking potential.
