I switched to the larger setting. It looks lots better than the smaller one. The colors are kind of bright on my screen, but I can see the game well enough. IYT uses purple for Keryo Pente also, but theirs is muted a little and seems easier to view on my screen. On this site the Keryo Pente graphics almost have an over saturated appearance on my screen.
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
