"description": "With everything that is going on in the world today, many people are stressed. I decided to try and make a stress free tournament. There are no time limits so if you need to something else, you don’t need to stress out about timing out of one of these games. I only ask that if you are on and you see one of these games, please actually play. If I suspect that you have stopped using this site, I will send you a PM before I call the games to the opponent. This is not a threat, just me making sure that the tournament actually goes on. Hopefully soon everything will be back to normal and no one will be as stressed. Well for now, Take it Easy😎",
