Bu Xiangzhi (Black) Puzzle: Fork — Bishop Tactics

A bishop fork is especially powerful when it lands on a protected or untouchable square and attacks two valuable targets at once. In this middlegame position, Black’s bishop can exploit weak light squares created by White’s isolated pawns and exposed back-rank pieces. The key tactical point is not a direct attack on the king, but a forcing double attack that leaves White unable to preserve both threatened pieces. Such combinations often turn a small structural edge into decisive material gain.
