January and February are traditionally the least busy time for professional Go players and there are fewer major tournaments. It is probably for this reason that back in January 2012 a special tournament was arranged between China and Korea. This is repeated in 2013. The tournament is rather informal and has no sponsor. Korean players have to pay their own expenses travelling to Beijing. Nevertheless many top Korean players do choose to participate, including Park Jungwhan, Cho Hanseung, Kang Dongyun and some of the best new stars like Shin Jinseo and Shin Minjun. The host of course also sends its best players to compete.
