Intermezzo Advanced Puzzle (Rated 1817): Intermezzo — Check

An intermezzo is a forcing in-between move played before carrying out an obvious capture or defensive action. In this chess endgame, the key idea is to use check to disrupt the opponent’s coordination, gain time, and exploit an exposed or undefended piece. The tactic works because the checked king must respond immediately, allowing the attacking rook to improve its position while preserving the threat of a decisive material gain.
