There are a few exception in the rules of chess; things like pawn promotion, castling, and en passant are exceptions to how the pieces move. Castling is very commonly seen in chess games, pawn promotion is a lot less common, and en passant is almost unseen. It is so rare that many casual player do not know the rule or are confused about it.By the way, En Passant means “in passing” in French.
Here’s what poppin:
En Passant can only happen the move after your opponent moves one of his or her pawns two squares up. If your pawn is to the side of your opponents (which just moved two squares) you can go diagonally to capture it. Here what it looks like:
Your pawn moves forward to c5.
You opponent moves from b7 to b5.
You then capture the pawn on b5 by moving to b6 with your pawn from c5.
