French Defense Sacrifice Intermediate Chess Puzzles

In the French Defense, a sacrifice at the intermediate level usually appears after the defining pawn chain forms with White pawns on e4 and d4 facing Black's e6 and d5. The idea is to give material to break the center, open lines against the king, or exploit the tension around c3, e4, or d4 in structures like the Advance, Winawer, or Classical French.
