Opera Game Puzzle (Rated 884): Win with a Fork — Philidor Defense

This Philidor Defense puzzle shows a classic tactical idea: a forcing check that creates a fork and wins material. In the middlegame, active pieces and king safety often matter more than raw material, and here the defender’s king is too exposed to coordinate. The key lesson is that a checking move can be more than a king attack—it can also redirect the king and open the path for a decisive fork on a valuable piece.
