How to play
- Chinese area scoring: living stones plus surrounded empty points; Black gives 7.5 komi (0.5 with handicap 2+).
- Captures remove groups with no liberties; suicide and repeating the whole-board position are forbidden.
- Two consecutive passes start scoring: tap a stone to mark its whole group dead or alive again; the game is scored once both accept, and either player may resume.
- Byoyomi timeout loses; only online 9×9 games count for Elo. AI is weak on 19×19—practice on 9/13.
