Bu Xiangzhi (Black) Puzzle: Capture — Mate

A capturing-defender tactic works when a key guarding piece is removed with tempo, often by check. Here, White appears materially ahead and active, but the exposed king and overloaded defenders matter more than the material count. Black’s attacking pieces coordinate on open lines and vulnerable queenside squares. The first tactical blow removes a crucial defender while forcing the king into a restricted path, turning apparent defensive resources into liabilities.
