What is typical of this opening, whether the move chosen by White is the marked one or one of the variants, is that the upper left corner is occupied by Black and the lower right by White. And if this opening occurs as the first skirmish, which is typically the case, the top right corner will also have a black stone.
This whole-board configuration is nearly always implicit in choosing the nadare in the first place, but in this particular line it is has been so close to a 100% rule that any game that differed would scream out "amateur!" This wouldn't be a variation as much as a contravention of go theory, a revolution not a new move.
Well, we have a revolution on our hands. In the Korean Baduk League on 30 October 2004, Heo Yeong-ho 3-dan, one of the brighter stars, played this way but with a shared corner in the lower right and a White position in the upper left. That is, he initiated the nadare, playing Black, and allowed the marked stone to be played against him. He lost.
But that did not stop Sakai Hideyuki 6-dan trying it on 31 January 2005 in the NHK Cup. In his case the contrast was starker - the lower-right corner was not shared in this case but occupied solely by the "wrong" colour - Black. He lost as well.
From Korea to Japan then China. The latest recruit to the revolution was Zhu Yuanhao 2-dan, who has only just become a teenager. He very impressively made it to the final of the 4th King of the South-west where he cheekily tried this against no less than Wang Lei 8-dan. He lost, too, but at least Wang's choice of opening was criticised by Luo Xihe.
The losses cannot hide the fact that three young and upcoming pros, supported at least to some extent by a 9-dan commentary, think they have seen something that allows them to challenge standard fuseki theory. It will be fascinating to see whether their revolution can gather any momentum.
