[Retros] More than 100 positions leading to the foolish mate. Yefim 10/09/2004

[Francois Labelle]

Win/XBoard aren't broken, they report Forsyth-Edwards Notation (FEN),
which isn't an exact match for the concept of "chess position".

Starting from the initial position and playing "1. e4" gives the en
passant target square e3. Nothing is wrong, the FEN specifications say:

"An en passant target square is given if and only if the last move was a
pawn advance of two squares."

So, ok, FEN lists some rights that you cannot possibly exercise. This is
not a problem because sometimes it doesn't matter, and when it matters it
can be figured out.

FEN is good because it gets the job done and is easy to specify and to
program. Think of the programmers!
