Endgame Puzzle (Rated 1678): Win — Rook Endgame
This chess endgame is decided by active piece coordination and the exposed king. White’s rook and bishop work together to give forcing checks, restrict the opposing king, and create a tactical attack on a vulnerable rook. Although the material is equal, king safety and piece activity give White a decisive advantage. The key strategic idea is to use tempo-gaining checks before the opponent’s outside passed pawn or passive pieces can generate counterplay.
