Krishnan Sasikiran (Black) Puzzle: Pin — Win Material
This chess endgame demonstrates how active pieces can overcome a material deficit. White’s rook and bishop coordinate against a king-protected bishop, creating a pin and skewer at the same time. The key idea is not an immediate checkmate, but a forcing sequence that restricts the defender and wins material. When a piece is pinned to its king and has no useful escape squares, checks can make the tactical pressure decisive.
