Bu Xiangzhi (Black) Puzzle: Spot Lolli's Mate — Net

Lolli's Mate is a classic mating pattern in which heavy pieces exploit a king trapped along the edge of the board. The attacking queen delivers forcing checks while a rook controls escape squares and supports the final net. Here, Black's active queen and rook coordinate against White's exposed queenside king, whose weakened pawn cover and limited flight squares make king safety the decisive imbalance.
