Hello how may I help you? Hi! I need help with a game. Ok, what game do you need help with? I need to know how to use an en passant in chess. An en passant is a special pawn capture that you can only do after a pawn moves two ranks forward and an enemy pawn that could've captured it moved forward only one square Okay. Can I use it more than once? No this move can only be performed once per game. Okay Thanks. Is there anything else I can help with? I think that's all. Thanks! Your welcome. Have a good day.
