Capturing a Pawn “en Passant” or “in Passing”

A Pawn that is on the fifth Row can capture a rival pawn which, from its initial position, has just moved two squares on an adjacent file.
This move is called Capturing en Passant and can only be made by the Pawn on the fifth Row and right after the turn of the Pawn that has moved two squares

White tries to advance his Pawn “c” by means of “double step”

White moved 1. c2-c4

Black can answer:

1. ... dxc3 in this turn.

If this opportunity is not taken now, this Pawn can’t be taken “en Passant” later.
