Borg Defense Intermediate Puzzle (Rated 1482): Win Material — Fork & Capture Defender

This middlegame puzzle shows a classic tactical refutation where one active piece can force a sequence of exchanges that wins material. The key idea is to combine a capture on a defended piece with a fork against the king and a loose minor piece. In positions like this, king safety, piece activity, and hanging pieces matter more than static material. The side to move can turn pressure on the center and kingside into a decisive advantage by exploiting tactical geometry.
