It also uses random pairing in all steps so that you get to play not in slaughter mode (against the strongest/weakest), but someone you would not normally play with.\n\nThe previous tournament (https://online-go.com/tournament/128245) uses double elimination, which seems to be waiting for everyone to finish - not in this one!\n\nMore to read for those who are interested:\n\nhttps://en.wikipedia.org/wiki/McMahon_system_tournament\n\nhttps://senseis.xmp.net/?McMahonPairing",
