Pick lines from the opening book, then play every book move for both sides. The board is the same trainer used on the opening pages. The schedule lives only in this browser.

Questions
Where are my lines stored?
In this browser, under the key pp-repertoire. There is no account, and the list does not follow you to another device.
How does the schedule work?
A finished line with no wrong moves is due again in 1 day the first time, 3 days the second time, and then the previous gap times 2.5, rounded to a whole day. A miss sets the line due today and clears the gap.
