"description": "Inspiration: Since our group is a Worldwide group, I'd like to dedicate some tournament themes to international holidays. May 8th is the World RCRC day! So I'm going to dedicate a tournament to it. \n\nTournament Info: This Tournament includes everyone from 25kyu-9Dan+. No handicaps are given! And since the RCRC organization is known for assisting people, this tournament will allow Conditional Moves and Analysis. Please be sure to use it wisely. Lastly, only 30 max can join, so hurry up and sign up!",
