Vienna Game Fork Intermediate Puzzle (Rated 957): Win a Fork — Crushing Middlegame Tactic

This puzzle comes from the Vienna Game and shows a classic middlegame tactical shot based on a crushing fork. White’s active pieces coordinate against the black king and overloaded defenders, creating a position where one forcing move wins material and keeps the initiative. The key idea is to use a check to drag the king into a worse square, then exploit the exposed pieces and weak coordination. It is a strong example of how tactical pressure can outweigh a small material deficit.
