I have been studying chess using Anki, which is a great libre flashcard program (ankisrs.net), mainly using screenshots of positions and the correct lines or a screenshot of the solution on the back of the card.
Someone developed an interactive chess Anki system that allows you to import PGN or FEN positions, for example, from studies or puzzles. Check out his video:
