Delaying tactics are not allowed.\n\n2. AI/robot is not allowed.\n\n3. The Rank Restriction based on the Correspondence 9x9 rank rather than the overall rank. And 4 kyu and below means not higher than 3.1 kyu.\n<h2>Attention</h2>\n<h3>Speed and Time-out</h3>\nKeep in mind that the avg speed of one game is 2.5 moves per 24 hrs.\nSince the Round Robin will activate several matches at the same time, for a match with five players, the avg speed is 10 moves per 24hrs.\nTo avoid losing by time-out, the safe way is to play fast than the avg speed (and consider the time zone issue).\nLoss by time out will affect your valuation in this Match system -such as disqualification and/or demotion to a lower level.\n<h2>Tips</h2>\n<ul>\n<li>If you are not familiar with Absolute time control, you may do some practice in a friendship game (ranked or unranked). </li>\n<li>Use <strong>Plan Conditional Moves</strong> to speed up</li>\n<li>Communicate with
