French Defense Marshall Gambit Fork Puzzle (Rated 1134): Win a Fork — French Defense Tactic

This French Defense puzzle is a classic opening tactic where activity and piece coordination outweigh raw material. Black’s queen can jump into the attack with check, forcing White to react while the bishop on b5 and the knight on c6 are tied up by tactical pressure. The key idea is that a forcing move creates a fork-like threat against multiple targets, turning a seemingly equal middlegame into a winning material sequence.
