DAE HYUK KO 7D WINS ’10 COTSEN

Monday September 20, 2010

Dae Hyuk Ko 7d (l) won the Cotsen Open last weekend in Los Angeles, California, besting a very tough Open section in which a lot of hard-fought games were played over the course of the two-day tournament. More than 150 players turned out for the 20th annual competition, one of the biggest and richest on the annual American Go Association tournament calendar. The popular event, founded and run by longtime local go fan and entrepreneur Eric Cotsen, is also a unique tournament, the only one to feature free shoulder massages from roaming masseuses, a free catered lunch on both days, a club competition with a $1,500 prize pool and full refund of registration fees to players who attend both days of the tournament. Another highlight was the online pro-pro game Sunday morning between Yilun Yang 7P and Yigang Hua 8P in China, which Yang then commented on afterward. In addition to being available to review player games, Yang ran a competition to correctly solve life and death problems that had players clustered over boards throughout the playing area working on the problems. This year’s tournament also hosted a planning meeting for the 2011 U.S. Go Congress, which will be held July 30-August 6 in nearby Santa Barbara, California and already has close to 100 pre-registered. The American Go E-Journal once again broadcast top-board games on KGS, some of which were commented by Jennie Shen 2P; EuroGoTV also hosted a live video feed of Board 1.
