En passant - Simple English Wikipedia, the free encyclopedia

In chess, en passant (in passing in French) is a special move for pawns to capture. First, if the pawn moves 2 squares from their starting square and stands next to an opponent pawn, the opponent's pawn can take the pawn 1 square diagonally in front of the pawn away from their square.

En passant move (If the white pawn lands on X the black pawn will be captured)

If there is no en passant rule, the game will be slower leading to blocking pieces and etc.^[1]

The en passant rule was invented to prevent pawns being stuck with the opponent's pawn on the same file.^[1]

It is also not a bug, a glitch, a hack or an illegal move, it is actually a real move, because it is a special move for pawns to capture.^[2]

If the white pawn moves 2 squares from their starting square and stands next to a black pawn, the black pawn can capture the white pawn 1 square diagonally away from their square in front of the white pawn by using en passant. Or, if the black pawn moves 2 squares from their starting square and stands next to a white pawn, the white pawn can capture the black pawn 1 square diagonally from their square in front of the black pawn by using en passant like the black pawn.

• It has to be a pawn that moves 2 squares forward from their starting square and it stands next to an opponent pawn and the opponent pawn will capture it.^[3]
• It cannot be used for later turns.^[3]
• The pawn can capture 1 square diagonally away from their square beside the opponent's pawn and the opponent's pawn will be taken behind.^[3]
