Four Knights Game Fork Intermediate Puzzle (Rated 890): Win with a Fork — Decisive Material Gain

This middlegame puzzle shows how a single active knight can create a decisive tactical swing. The key idea is a fork that hits multiple high-value targets at once, forcing the opponent into a narrow defensive path. In positions like this, material balance can hide the real danger: one piece becomes overloaded, king safety is reduced, and the opponent’s queen and bishop coordination starts to collapse. The winning side uses forcing play to convert activity into a large material gain.
