Title: Where Does Lichess Get Its Names for the Openings?

  (Asked by: username_0 on 2022-02-28)
  
  On lichess.org, when you turn the opening book on in an analysis board, you get names for the openings. For example, after 1.e4 d6 2.d4 Nf6 3.Nc3 c6, lichess says the opening is called "Czech Defense." Many openings have standard, accepted names, but sometimes there is disagreement, especially with deep variations. There is also sometimes disagreement between different playing platforms. For example, sometimes chess.com uses different names than lichess. What sources provide lichess all of the names?
