"description": "You are expected to comment your moves in your Malkovich log. You are also expected to play reasonably fast so that the tournament ends within a couple of weeks and everyone can discuss the games together.\n\nWhile we don’t want to make any strict rules about no holidays at all or how much you need to write in your log players can and will be disqualified if they still neglect these things after a warning.\n\nYou are also encouraged to comment on other players’ games. You have three games of your own and three games of other people to comment upon.\n\nPlease sign up only if you are interested in an active and interactive learning tournament.\n\nIf you want to get notifications of Malko tournaments sign up to the group https://online-go.com/group/794\n\nIf you want other rank restrictions or settings contact me or simply start another tournament from my Malkovich group.\n\nAt the start of your game, copy and paste the following text into your game chat:\n\n*\n---------------------\nMALKOVICH GAME\nRecord your thoughts and possible plays/outcomes in your Malkovich log as you play to help you during the game and others when they review it. \n---------------------",
