Question can any other piece apart from a pawn(example a knight) capture an enemy pawn en passant?
Answer Hello Cany, thank you for your interesting question. The short answer to this is no, en passant captures can only be made by pawns. Now the long answer. In the very early rules of chess, pawns could only ever move one square at a time. To speed up the game it was decided that on a pawn's first move it could move one or two squares, whichever the player chose. Now this brought the two armies in to contact quicker and speeded up the game, but it also meant the possibliity that a pawn could move past an enemy pawn and avoid the risk of capture. This was seen as an unfair advantage. So imagine white moved his pawn from the start square, say e4, three squares up the board, to e6. This would take two moves to do this. The black player has a pawn on d7, the start square and now moves it two squares on its first move. Well it would end up on d5 and would have moved past the white pawn on e6. So to cancel out the advantage the en passant rule was introduced - big fanfare for the en passant rule - whereby the pawn on e6 gets to capture the pawn passing it on the square d6. Now note the en passant rule only relates to the pawn moving on its first move and choosing to move two squares. So there you have it, en passant is a rule only for the pawns and there are no captures by the other pieces as they move past each other. I hope that this helps and that you enjoy your chess, Very Best Regards Peter.
