Owen Defense Guatemala Defense Puzzle (Rated 1043): Fork — Chess Endgame Tactics
This chess endgame puzzle shows how a single active knight can create a decisive material swing by attacking two targets at once. The key idea is a fork: one piece jumps to a square where it hits multiple valuable pieces, forcing the opponent into a losing sequence. In classical chess, these tactical shots often appear when rooks and bishops are slightly loose and king safety is not enough to compensate for material imbalance.
