Yugen Cup is a Japanese professional tournament begun in 2007. Fifty players, comprising forty-five professionals and five insei, compete in 6 rounds. There is a ¥500,000 grand prize (roughly $4,600 USD).
Tapir: Can someone explain sth. about this tournament. There are several players with perfect 6:0 score in 2007. They're competing but who won? How they decide who has won? Does .sgf-kifu exist?
valerio: Yigo.org ( http://www.yigo.org/modules/news/article.php?storyid=2124) says that Ko Iso 7 dan was the winner of the first edition (2007-2008; view also Ko profile at Nihon Kiin: http://www.nihonkiin.or.jp/player/htm/ki000384.htm).
Second edition started on 2008-04-28 and each player will play 12 games, instead of six. The winner was Iyama Yuta of a perfect score of 12 wins.

tapir: SOS 3? - after playing eight matches? can it be the messed up with the tiebreakers somewhat? ah they are seeding top players against insei and new pros so they end up with a lot of 8-0, 7-1 and 0-8, 1-7 final scores.
