Count the points! Japanese rules, no komi, no prisoners. For example, if black wins by 5 points you'd click "B+5". Note - "Jigo" means "Drawn game". To clarify, this position is still in the main phase of the game - no passes have been made. (If anyone can comment on how passes affect the position, please do!)
