I'd love to hear if anyone else has more
How many opening book achievements do you have here?

I have 32.
I only have 16 but I wasn't really trying to collect them. Does anyone know if the games have to be rated, or does unrated count? If unrated counts, then a bunch of us could play unrated chess and agree to use openings listed, so we all can get 32 or more

I'm trying to get all of them
Gotta catch 'em all?
