ghost achievements?

Which achievements are you seeing notifications for?

me too I see achievements like "sicilian", or "scandinavian" and so on and so forth . it s basically a notification in which appears a small chessboard with that word on top, but I can t spot them in my achievements list or the list of achievements still to be reached. so what s the deal?

The ones with opening names show up in a different section.
- Achievements: regular Achievements
- Medals: for placing in events
- Badges: given by other members based on a game you've played with them
- Cheers: fun trophies
- Books: for playing certain book openings
