Great Snake Variation Puzzle (Rated 942): Spot a Fork — Modern Defense Tactic

This puzzle is a classic middlegame tactic from the Modern Defense where White uses a forcing knight jump to create a fork against the king and queen-side pieces. The position shows why king safety and piece coordination matter more than raw material count. Even when Black appears ahead materially, a single tactical weakness around the king can overturn the evaluation. In practical classical chess, these motifs often decide the game before the endgame ever begins.
