Biggest WAGC-2011 sensation: Norway beat Japan!
The biggest sensation so far: Morten Ofstad, 4-dan from Norway beat Hirata Hironori (Japan).
I decided to post the game in WBaduk section, because I got the kifu (or gibo, as they say in Korea) on WBaduk server.
This game is similar to Geert Groenen (5-6d from Holland) vs Hiraoka Satoshi happening (WAGC 2008 or 2009). That time Hiraoka was ahead, but he was not careful enough in late yose. He played sente move, but instead of defending Geert played big sente move too. Hiraoka thought that his opponent answered, so he played another yose in different part of the board. After that Geert killed some stones and Hiraoka immediately resigned.
Morten played well, but of course it's hard for regular 4d to beat Japanese champion. He was very lucky at the end - he killed big group, because of Hirata's mistake in late yose.
White was 5-6 points ahead, in case of the normal endgame (if he saves the group and sacrifice 1 stone)
