[Retros] En passant chess : self-defense

[Pascal Wassong]

Hello,

with the rules I have seen on the ep chess, it is not made clear to me
that a piece being captured cannot take en passant the piece that
wants to capture it.

For example : wQe1, bRe8 : can Re8xe1 be stopped by Qe1xRe2 ?

In some metaphors given on this list, that should be possible.

If this is possible, is mate possible ?  I think so : the King must be
threatened by a Knight, or by a piece being in contact with the King.


Having fun,
Pascal
