why en passant?
Regarding the quation: Why en passant?
I have read somewhere that there was once a time when pawns could only move one step. Then when the possibility to move a double-step was introduced in the 15th century the en passant rule was included in order to prevent a pawn to move two steps without the risk of being captured.
The rule gives a nice spice to the game in my opinion.

Yeah! And while we're at it, why castling? Stupid cowardly king running away into the corner while simultaneously bringing out the rook. The king should stay in the middle and fight like a man.
And what about that stupid pawn promotion rule. A passed pawn should get to the eight rank and just sit there and gum up the works. Just when I think I'm winning, the stupid pawn promotes to a queen and I lose.
Come to think of it, why have the rules at all? The pieces are attractive and fun to handle, so I think we should just move them around any way we feel like it until, maybe, checkmate happens purely by accident. That's how my 3 year old grandson plays, and it's a lot of fun. Food for thought.
I hate en passant. There should be better solution.
