French Defense Advance Variation En Passant in Chess

In the French Defense Advance Variation, White plays e5 and builds a pawn chain with pawns on e5 and d4. The “en passant” motif appears when Black’s pawn advances two squares past White’s pawn on the adjacent file, allowing White to capture it immediately as if it had moved only one square. In this concept, the defining feature is the Advance pawn on e5 (or d5/d4 depending on the exact move order) creating an en-passant capture right after the two-square pawn push.
