how do en passants work?!

If a pawn moves 2 squares forward and is horizontal with your pawn, you can take diagonally. I think they made this rule so you couldn't just move past another pawn that easily, but I agree it is strange.

It was an adjustment made after the rule for pawns to move two spaces on their first move. The initial two space movement was used to speed up the game. Without the rule it makes creating passed pawns more likely without your opponent being able to stop you.

An En Passant is the act of a pawn to a space horizontally above a pawn that had just made their initial 2-space leap. This was created mainly to make the game seem harder, and more playable.

Its a rule of capture in chess, one of the rarest moves to ever pull off. as both pawns must move 2 spaces forwards (the initial leap, not just going say, e3 then e4, that wont allow it to happen) and then you only have that one turn to En Passant, if you don't do it within that turn, you lose the chance. Noahfavelo and LovelyJericho give a better explanation than me, if you need more knowledge.
