Sure thing. This is my own alternate version of the file eco.pgn, which comes with the pgn-extract software. The original is used as a template to fill in opening tags. It's essentially a list of named openings, but it doesn't pay much attention to capitalization or consistency. So I've always intended on making a new version.

Yesterday I discovered this GitHub page: https://github.com/lichess-org/chess-openings This is where Lichess keeps a list of every named opening in its explorer.

Here is a formatted version of that list:
https://chessnerd.net/lichess-named-openings.txt

And here is that list turned into a new version of the eco.pgn file:
https://chessnerd.net/eco.pgn

Hope all are well.

And for those members like me who have the original eco.pgn all over the place you could use this Windows terminal command to replace with the new FritzUser version .. the quotation marks are needed ..


replace "C:\Your\ecopgn\Location\eco.pgn" "C:\Your\Destination\Folders\" /s

replace "C:\Your\ecopgn\Location\eco.pgn" "D:\" /s
