How do you do en passant on chess.com?
Imagine that pawns are soldiers on foot. They have to ride a jeepney in order for them to reach the second square fast. On their way, they are ambushed by other soldiers. En passant works the same way. "En passant" means "in passing". The rule of en passant says that when a pawn moves two squares on one turn, the very next move an adjacent pawn may capture that pawn as if it had only moved one square.
still not working for me can someone tell me how im on computer
You capture en passant exactly the same way as you capture anything else with a pawn with a one square diagonal move.
