Correspondence games: opening books vs. lichess studies • page 1/1 • General Chess Discussion • lichess.org

Lichess rules for correspondence games allows the use of opening books. My intuitive understanding of "opening book" is:

they are something like this or this; and
Lichess studies don't count (i.e., Lichess studies are not allowed to be consulted during correspondence games).

Is this understanding (especially the second item) correct?

You will be much safer if you use the opening explorer that Lichess offers (book icon).

See Chess Opening Book. They usually include diagrams and tree structures - just like your examples. When you play a Correspondence game here and click on "Analyze" (the little microscope), you'll see a little book icon. Behind it lies—well—a sort of opening book with a sort of tree view.
