What makes our matches unique?

\n\n
    \n
  1. The matches are true fast correspondence, — more than 2 moves per clock day.
    2. \n
  2. We have a Rank Difference Compensation policy which makes matches close, and lower-kyu players have more opportunities to get a good place.
    3. \n
  3. We use 'type rank' (such as 9x9 cor. rank) rather than the overall rank.
    4. \n
\n\n
\n

Additional rules

\n\n
    \n
  1. Pause or Vacation mode is not allowed
    2. \n
  2. The participants whose ratings are far higher/lower than the average ratkings of opponents will get adjusted points; for instance, 2 kyus higher or lower will be plus or minus 0.5 result points.
    3. \n\n
\n\n

Attention

\n\n

Speed and Time-out

\n\nKeep in mind that the avg speed of one game is about 3 moves per calendar day (or 12 hrs of your clock time) per player. Since the Round Robin will activate several games simultaneously, for a match with five players, the avg speed times 4. To respect your opponents and the match organizer, please try to avoid time out as far as possible.. \n\nLoss by time out will be labeled as \"disqualified\" on the table by OGS' program automatically.\n\nLoss by time out will affect your reputation in this Match system.\n\n
