Endgame Puzzle (Rated 1566): Calculate — Intermezzo
An intermezzo is a forcing move played before an expected recapture or routine response. In this rook endgame, the key idea is to recognize that an attacked rook can create a stronger tactical opportunity elsewhere. White combines active rook placement with pressure on an undefended queenside pawn, transforming a material deficit into a decisive advantage. This is a classic chess endgame lesson: activity, forcing moves, and tactical priorities can matter more than the immediate material count.
