Frequently Asked Questions

What chess openings are included?

Our database includes 150+ openings covering all major ECO categories: Flank Openings (A00-A39), Queen's Pawn (A40-A99), Semi-Open Games like the Sicilian and French (B00-B99), Open Games like the Italian and Ruy Lopez (C00-C99), Closed Games like the Queen's Gambit (D00-D99), and Indian Defenses (E00-E99).

How does practice mode work?

In practice mode, you play through an opening line on an interactive board. The opponent's moves are played automatically. If you deviate from the book move, you'll be shown the correct move and can try again.

How does quiz mode work?

Quiz mode presents you with a position from a random opening and asks you to find the book move. Your score tracks correct answers, incorrect answers, and your current streak.
