Oh, wow, it is right there in the pgn, but in the list of games its shown as undefined.
labeling "undefined" openings for games in the db
Sort:
OK, so I'm confused about this. As Fezzik points out, the opening is in the PGN-- often at least. But when you look at the list of games you see lot of A - 00 Undefined games, even though their pgn will have it in it.
for example:

But if you just opening the pgn you get ECO C47:
this seems fixable, and by this I mean the listing of the game as undefined on the games list.
I've been using the game explorer db here and notice that when a game's opening is listed as "undefined" it just means that no one labeled the opening. I looked today at a game between Jonny Hector and Evgenij Agrest, which is listed as undefined but is a Semi-Slav.
Is there a way we can label these games? It would take some time but eventually we could accurately label some chunk of these games. I think it would make the db a lot more useful.
here's the game, but I've seen a bunch of undefined games that are pretty easy to define:
