Learn suggestions
Two dials steer what Hard Lines offers next: how to order moves inside a course, and how fairly to share turns across your library.
1 · Within each course
Breadth vs depth
Breadth studies every reply before going deeper; depth unlocks the move that opens the most lines.
Breadth 75%
BreadthRecommended
Early moves first, with a little weight for busy lines.
2 · Across courses
Course balance
Large repertoires pack more early moves. Balance catches up on courses where you know fewer moves until totals match, then shares evenly; Priority ignores course size and only uses breadth/depth.
Balance 100%
BalanceRecommended
Catch up on courses with fewer learned moves until totals match, then share evenly.
Breadth/depth also applies to Map priority gaps. Course balance only affects Learn-all suggestions.
