"description": "Halloween tournament! If you don't celebrate Halloween in your country - it's a holiday where we celebrate things that are scary and pass out candy. So let's make this a scary tournament! 5 day time limit. No pause on weekends. Slaughter pairing. No rank restrictions. No handicap. No analysis. Chinese scoring (not sure why that would be scary...). At Halloween you also give out candy. So just remember - don't eat your go stones! They are not candy!",
