Do I need to know my chess rating to start?

What chess training tools are included?
A daily puzzle with streaks, themed puzzle practice and puzzle rush modes, an opening repertoire builder with spaced repetition, an endgame trainer covering essential technique, and sparring games against an engine tuned to your rating.
Is this suitable for chess beginners?
Yes. Puzzles and sparring difficulty automatically adapt to your calibrated rating, so complete beginners and experienced club players both get an appropriately challenging experience.
How is the e-Trainer connected to Chess Global League?
The e-Trainer shares your account with Chess Global League, the monthly online and local chess league. Training here builds the same skills and the same Elo rating you use to compete in league rounds.
