Russian Game Fork Beginner Puzzle (Rated 1185): Crush with a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of a crushing fork that turns active piece placement into a decisive material gain. White’s pieces are coordinated around the enemy king, and the key idea is to use a forcing check to drag the king into a worse square before a knight jump creates a double attack. The position also shows how a pinned pawn and a weakened king shelter can make a seemingly solid defense collapse quickly.
