Praggnanandhaa (White) Puzzle: Use a Pin — Win Material

A pin becomes powerful when the pinned piece is both valuable and unable to escape. In this chess endgame, a bishop attacks a rook that is aligned with the king, creating an absolute pin. The defender cannot move freely without exposing the king, so White can exploit the restriction and regain material. The position also features a passed pawn, making the tactical idea stronger: the pin removes a key defender while the pawn creates an urgent promotion threat.
