After the success of the pilot event, the inaugural UK Open was held on June 26th 2010. Supported by official recognition from the EMA, with MERS ranking points at stake, and with the assistance of publicity via Mahjong News a significantly wider participation was achieved. It was particularly pleasing that Martin Rep, editor of Mahjong News, was able to take part this time, and both surprising and gratifying that the President of the Korean Mahjong Association, Jaewon Yu, who chanced to be on holiday in Europe at the time, was available to compete.
Some very capable players from the Cambridge University Riichi Mahjong Club featured prominently, taking inter alia, second and third places, but on this occasion the clear winner was Ans Hoogland from the Netherlands.
