David Navara (White) Puzzle: Fork — Win the Rook

A fork is a powerful tactical idea in which one piece attacks two or more valuable targets at once. In this chess endgame, an active knight can check the exposed king while simultaneously attacking a rook. The king must respond to the check, allowing the rook to be collected afterward. This winning combination shows why piece activity, king exposure, and loose material often matter more than static material counts.
