Notes on Studies
—————-
Summary: Lichess users have a hard time finding documentation on the details of using studies. Here is (yet another) attempt at writing such a document.

– The study chapter limit is 64 chapters. 3/13/2018
– Embedding Lichess

– Making links to study/chapter. You can even choose the move number!
In the study under “Share & export” you’ll find the URLs.

Study Spectators/Members/Contributors
————————————-
Assume that a study is created and the study is set to
– Visibility: “Public”,
– Chat: “Members” ,
– Enable sync: “Yes: keep everyone on the same position”.
Definitions:
REC is green, REC is red: the first means REC has a green check
mark to the left, the second means a red “x” is to the left.
SYNC is green, SYNC is red: similar to above.
Non members:
* Anyone can visit the URL of such a study and they are a “spectator”.
* They cannot chat, but they see the chat conversation.
* They cannot comment on moves. They cannot use annotation glyphs. They
cannot request a computer analysis.
* They can use the share button.
* They can turn on Stockfish, use the opening book/tablebase, practice
with computer, etc.
* They can draw arrows/circles associated with a move.
* They can make variations.
* They can visit other chapters in the study.
* Nothing of what they do is saved to the server since
they cannot make permanent changes to the study.
* As soon as they make a change to the move list, or visit another chapter,
they get a “SYNC” button. A number appears to the left of that indicating
how many moves have been made by contributors – an indication that they have
fallen behind the conversation. Pressing the SYNC button gets that back to
the position of the conversation, and the SYNC button goes away.
Members:
* Can do whatever a non member can do.
* Cannot comment on moves – despite the message to the contrary!
Contributors:
* Can do whatever a member can do, because they are members.
* New buttons: REC, and !?. Contributors can make new variations, comments,
annotation glyphs (the “!?” button), and new chapters. They can delete
chapters! To make comments or annotate with glyphs, the REC button must
be green.
* NOTE WELL: Variations, and arrow/circles can be made with the REC
button red, but all changes will be gone when it is made green!
* Making the REC green enables permanent editing. Pressing it to red saves
the changes to the study on the server.
* All contributors can simultaneously edit the study and make permanent changes!
* On first visiting the study the SYNC and REC are green. Anyone who moves
around in the score or makes changes causes all participants who have SYNC
green to immediately see the changes! This will be very confusing; like
having people all talking at the same time. Hence, some kind of protocol
has to be established. If a person sets their SYNC to red, it will just
turn green when they press it to get back in sync.
Hence, what is needed is some concept of a contributor “having the floor”.
Perhaps a form of Robert’s Rules of Order. At the very least one needs
a “chair”, and concept of “having the floor”. The study owner would
normally chair the meeting and set protocol for asking for the floor.
