Field notes
The training cards are described as covering more than tactics: opening lines can be imported from a Lichess study, while missed Lichess puzzles return after enough time has passed to require recalling the idea again. The site also proposes a coin-flip drill that mixes tactical puzzles with quiet positions, so players have to decide whether a tactic is present before moving.
