Modern Defense Pseudo Austrian Attack Puzzle (Rated 866): Fork — Decisive Material Gain

This Modern Defense middlegame shows a classic tactical fork built around piece activity and king safety. Black’s knight jumps into the heart of the position with check, forcing the white king to move and exposing loose pieces. The key idea is that a forcing move can create a decisive material gain even when the position looks balanced on the surface. In practical classical chess, these motifs often appear when the opponent’s king is slightly exposed and several white pieces are overloaded.
