Italian Game Blackburne Kostic Gambit Puzzle (Rated 828): Win Material — Fork Tactic
This middlegame puzzle is all about forcing moves against an exposed king. White’s bishop creates a checking idea that drags the black queen onto a vulnerable square, where it becomes tied to the king’s defense. The follow-up uses a knight to capture with tempo and win material. The key lesson is that a check can be more than an attack on the king — it can also set up a fork, overload a defender, and simplify into a winning material edge.
