En Passant & How To Play En Passant

The chess term en passant is French for "while passing", en passant is a chess move relevant only to pawns. En passant can only be played in certain chess positions, in this diagram the pawn's on c7 and g2 are in the starting position. If the player commanding the pawns in the starting position (g2 andc7) chooses to make a double jump, or move two squares in one turn (an option only allowed to the pawns first move) this is called "passing", now the pawns on f4 and b5 have the option to capture the enemy by using en passant and moving to c6 or g3. The attacking player's pawn ends up on c6 or g3, right behind where the other players pawn was. This is called en passant, or taking while passing. However en passant cannot be played if the pawns in the starting position only move one space at a time, taking two moves to pass the opposing pawn, if the opposing player (b5 and f4) tries to capture using en passant rule when you have not done a double jump that is an illegal move. En passant can be played using any of the pawn in similar positions on the ranks and files, such as, white can only capture en passant while on the 5th rank and black can only capture while on the 4th rank, and you can only be captured using the double jump to pass them.
