"description": "Господа, проводим быстрый турнир со стартом в 20:00. Если вы записываетесь не забудьте быть онлайн в это время, а лучше даже заранее. Именно в это момент пойдет отчет времени в вашей первой партии. Длительность турнира зависти от количества участников. Но будьте готовы к 30 - 50 минутам. Постарайтесь не пропустить свою игру.\n\nВыбывание идет после 2-х поражений, так что не уходите после проигрыша. Новый тур начинается когда будут сыграны все партии текущего, будьте терпеливы. Это будет недолго, плюс ко всему можно понаблюдать за чужими партиями.\n\nЧто бы попасть в свою партию вам будет необходимо: найти себя в «сетке» (она будет либо справа либо снизу от чата), слева от своей аватарки найти маленькую иконку с двумя камнями и нажать на нее.",
