Richard Rapport (Black) Puzzle: Win Material — Overload

An overloaded defender is a tactical piece forced to protect more than one important target. When its duties cannot be maintained, a lower-value attacker may create a decisive material gain. In this position, Black’s kingside coordination is strained: one piece is tied to defensive responsibilities while White’s active queen, rook, and advanced pawns increase the pressure. The key idea is to recognize that the apparent defensive setup is unstable and use a precise, forcing sequence to preserve the advantage.
