"description": "Welcome to the Nottingham Go Club October Online Tournament. We are still experimenting with the best time limits in order to create something that is fun and fair and doesn't take all day! However, we think that there is a bug in the software that stops the handicaps from working and so you might have some uneven games. We don't mind this as we think all Go games are fun and so we hope you do too!",
