Именно в это момент пойдет отчет времени в вашей первой партии. Длительность турнира зависит 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.",

Please make sure at the beginning of the game that the handicap is somewhat appropriate (I think it only takes correspondence rank into account). If it is not, the advantaged player is invited to pass as many times as necessary to establish balance. \n\nSince this is a learning group, reviews are encouraged.\n\nHave fun!",
