The opening pattern up to white 8 has become very popular quite recently and appeared in several SportAccord games.
Up through black 71 (the marked stone in diagram 1) the position is about even. White appears to have more territory, but the white position on the lower side is thin and can easily be invaded, so black is not behind. In fact, if black had played 71 at 1 in diagram 2, black might well have been ahead. White cannot cut black apart. Given the continuation through black 9, black is solidly linked up and the white group cannot make two eyes on the right side, so black will be able to attack it in the center.
The move that Ida Atsushi chose for black 71 was readily answered by white 72, and black 73 let white break up black’s right side territory in sente with 74 and 76. Aside from losing territory, black was placed on the defensive, and would be hampered in going deeper into the white territory at the bottom.
From this point on, the fighting in the center became quite confused. White’s top group seemed to be in trouble, but it could never be killed unconditionally, except at the sacrifice of an even larger black group. When white 168 connected the ko in the top left, white had a clear territorial lead.
By white 186 black’s position had become untenable and the Japanese pair resigned.
