Capturing en passant
Back
can exercise when any of his Pawns has reached a certain point.
This is possible only if all of the following conditions are present:
- The Pawn that will do the capturing must be on its fifth rank.
- The Pawns involved must be on adjacent files.
- The Pawn that will ultimately be captured must still be on its
second (original) rank (see diagram 1). - Tha Pawn that is to be captured advances two squares (see diagram 2).
- In reply, the opposing Pawn captures the first Pawn as if it had advanced
only one square (see diagram 3).

Usually capturing en passant is optional, but if a player does not
capture in passing immediately (right after the opponent moves a Pawn
two squares on its initial move), than he loses his option.
There is one instance when capturing en passant is compulsory.
the capture must be made.
There is also one instance when capturing en passant is not allowed.
