Opening Trainers & Repertoire
Build, memorise, and drill an opening repertoire. Modern trainers use spaced repetition and, increasingly, AI to quiz you on positions you actually reach in your own games.
An opening repertoire is only useful if you can remember it under pressure. The tools here combine a repertoire editor, spaced repetition scheduling, and — in the best cases — feedback on whether your lines match what strong engines actually prefer.
