You are looking for the Board Games room. Chess games are hosted there frequently and also there is a discord link in there. Also for further PS relate questions you should rather ask hereConfused about the chess room,
I wanna find out where this chess room is because it seems fun, but literally NO ONE wants to tell me where this is, if it's on teh discord, the main site, something different, I don't know. Could you please clarify where the room is?
