How do I browse for and learn/review a certain variation?

In Chessable, you can skip ahead to your favorite opening variations or exercises. From your dashboard, click on the course you want to browse. > Go to the appropriate chapter. > Find the variation or exercise you want to train and click "Learn" or "Review."

If you want to view the line/exercise's read-only version instead of training it, then click on the variation name.

If you do not want to skip to a variation and want to learn/review in a continuous manner, click on the "Learn Next / Review" button on the top right.  At the end of each exercise, you will have the option to move to the next one.
