Kings Indian Defense Exchange Variation Puzzle (Rated 1027): Fork — Crushing Middlegame Tactics
This middlegame puzzle is a classic example of a crushing fork based on piece activity and king safety. White’s bishop becomes an active tactical piece, hitting two valuable targets at once and forcing Black into a defensive response. The key idea is that an undefended rook and knight can be overloaded when one move creates multiple threats. In classical chess, these tactical shots often decide the game even when material is otherwise equal.
