Subject: Something cool about ExChess's log file

Author: Pete Galati

Date: 15:23:35 04/09/00


What Exchess does in it's log file it to generate an epd postion for each move,
I wish more programs did this, some might and I just don't know about it.

Here's a game where Exchess beat me, displaying the epd positions with [D] after
the opening.  I cut the game way short, no need to show the whole thing.
Hopefully I did this right.
