English Opening The Whale Puzzle (Rated 969): Win Material — Fork Tactic
This middlegame puzzle is a classic example of a tactical fork creating a decisive material swing. White’s knight jumps into an active square with check, forcing the king to respond while also attacking a major piece. That kind of double attack is especially powerful when the opponent’s pieces are overloaded or poorly coordinated. Even though Black has extra material, the active white pieces and exposed targets make the tactic work.
