En Passant Advanced in Chess

En Passant Advanced is an advanced tactical use of the en passant rule: you capture a pawn as if it had moved only one square, but only immediately after it advances two squares. The defining feature is the opponent’s just-played two-square pawn move that lands adjacent to your pawn, creating a one-move capture window. In practice, this motif often appears after moves like ...d5 (or ...e5) meeting a pawn on c4 (or d4) where the timing is everything.
