This is today's game in Korean Kuksu tournament: http://www.go4go.net/go/games/sgfview/43596

Lee Sedol 9p (Black) vs. Park Yeonghun 9p (White)

While fighting the ko at 'a', black :b1: appears to be a loss-making threat. But I did not realise at the time that black can not only create many ko threats but also form an 'under the stones' later. Can you see it?
