The Go to Everyone! section has eleven editions, up to this year, of what it calls the Shiduan.
I've ascertained that the early results are the same as those in this Youshi Shiduan.
What is the relationship between this tournament and the one called the Shiduan here, with editions in 2007 and 2008? Should one article be merged into the other, and the Youshi Shiduan considered a revival of the older Shiduan?
