## What is Go?

Go: One Move is a Go (Baduk / Weiqi) app where you play against KataGo AI.

■ An opponent at your level
Choose any rank you like, from 18 kyu to 9 dan, and play Go at that level.

■ Ranked matches
Sign in and get matched with an opponent that fits you. Your first match starts at 18 kyu, and as you win you'll face stronger opponents.

■ My Info: rank profile
Your nickname, rank and win–loss record are kept in your account, so you can pick up on any device.

■ Game records and review
Every game is saved to your account. Replay finished games move by move and check the AI's winrate graph and key moments.

■ AI coaching
At each key moment, see the moves the AI suggests with their winrates, along with a score estimate of the position.

■ AI hints while you play
Signed in, you can turn on AI hints and a score estimate during practice games.

■ Practice game
No sign-in needed. Play casually on 9x9, 13x13 or 19x19 boards.

■ Scoring and results
When the game ends, territory is counted under Korean rules (komi 6.5), with territory and dead stones marked on the board.

■ Placement helper
Two-step move confirmation helps you place stones precisely, even on a 19x19 board.

Signing in takes just an email code — no separate sign-up.
