Personal study set · Drill the whole list or pick a single line
Star any opening line in the trainer to add it to your Favorites. Use this list as a curated practice set — the lines you actually play in your own games, separated from the broader 885-line catalogue.
Drill the entire list in one sitting to refresh your repertoire before a tournament, or jump into a single line for focused work. Combined with Spaced Review, your Favorites become a reliable source of practice material that always reflects what you actually need to know.
