Ruy Lopez Exchange Puzzle (Rated 1101): Pin — Win Material
An intermezzo is a forcing move played before an obvious recapture or exchange. In this middlegame puzzle, White is materially behind but can exploit the alignment of the kings, queens, and rooks. A checking move changes the position’s geometry, forcing the king to respond while a pinned bishop remains vulnerable. The key idea is to prioritize checks and tactical threats over immediately recovering material, turning a defensive-looking position into a decisive material gain.
