Coercion Puzzle (Rated 600): Win Material — Chess Endgame
This chess endgame centers on coercion: one side uses active rook play to force a favorable exchange and win material. The key idea is to recognize when an undefended piece sits on a vulnerable square and can be removed with tempo. In simplified positions, activity often matters more than raw material count, and a single tactical shot can transform an equal-looking board into a decisive advantage. Look for loose pieces, overloaded defenders, and lines where one capture creates a lasting material edge.
