While updating http://senseis.xmp.net/?LeeSedolGuLiRivalry I came across their 31th game, the final of the "Gui Lin cup". Gui Lin appears to be a city in China but otherwise I only have this name at go4go.net, which is the major source for the SL page.

Does anybody know more about this cup? Does it have an alternative name? Must be, because there is nothing to be googled with Gui Lin cup, except the SL and go4go pages.

This is just a small invitational tournament held in Guilin city in 2012. Gu Li, Lee Sedol and Yoda Norimoto were invited. The tournament was not very well publicized, although there were plenty Chinese references to it. The full name of the tournament in Chinese is either 桂林中日韩职业围棋世界冠军争霸赛 or 桂林杯世界冠军争霸赛.

Thanks! I have added this information to Sensei's Library.
