  • This app hasn’t received enough ratings or reviews to display an overview.

Train now opens with openings picked for your rating, so you always know what to study next. Build a personal repertoire, then drill it with spaced repetition that brings each line back right before you would forget it. New reminders nudge you when reviews are due or an opening line is left unfinished. Plus performance and stability improvements. Thanks for playing, and see you on the board.
