Center Game En Passant in Chess

Center Game En Passant is the tactical motif where a pawn captures an enemy pawn “as if” it had moved only one square, immediately after that pawn advances two squares from its starting rank. In Center Game positions, this often happens when White plays a central pawn move like e4 (or d4) and Black responds with a matching two-square pawn advance, creating an en-passant capture right away. The defining feature is the temporary en-passant vulnerability on the adjacent file.
