Rook And Three Pawns Vs Two Knights Puzzle (Rated 1205): Fork — Endgame Tactics
A knight fork is especially powerful in a chess endgame because every exchange and tempo matters. Here, Black uses a forcing check to attack the centralized king while simultaneously targeting an active rook. The material balance initially favors White, but the rook’s limited escape squares create a tactical vulnerability. This is a classic example of how piece activity can conceal danger: an advanced rook may look dominant while actually being susceptible to a well-timed fork.
