For quite some years now the Following Iyama Yuta thread and its predecessor have served as effectively a "Japanese title match news" thread. But with Iyama losing a few (Gosei to Kyo Kagen, Meijin to Cho U, Judan to Murukawa Dasiuke) I thought I'd make this one for following the others.

A few weeks ago Iyama lost to Ichiriki Ryo in the semi-finals of the Gosei challenger decision tournament, and Ichiriki yesterday lost to Hane Naoki (below), so Kyo will play the first game of the final on 30th June against 21-years-his-senior Hane. Hane won 8 big tiles in the years 2001-2011 (most recent was the Gosei) and was last in a final in 2012 so this is something of a comeback for him. Can he do a Cho U and win a title some years after his peak?

White E6 and E13 are interesting. Kyo seems to be experimenting?

I think E6 is normal when one approach stone is pincered along its side ( C10 ) and the other has support along its side (N3).
It is white's move 20 at D3 instead of B5 that looks experimental to me.

e6 rather than one of the attaches isn't a move unseen before AI (e.g. Bao Yun likes it after double low approach to 2-space high pincer and I tried it in one of my British title matches), but it is a move I've noticed AI sometimes has a marked preference for over the traditional attaches, so that's probably behind Kyo using it.

Game 3 was a few days ago, Kyo won to stay in the match at 1-2 now (first to 3 wins). Next game is 9th August.

Kyo Kagen won the 4th game too to set up a deciding 5th game on 23rd August.



Following along with LZ, one moment I found particularly interesting was move 27, where LZ thought Kyo's haengma was poor and there was a much better way (FineArt in the Fox commentarary agrees). Instead of h6 attach, which simply gets black out to the centre (with some shape problems) and doesn't capture the cutting stones (though Hane gave them up later, he shouldn't have), he should have leaned/offered a sacrifice at k4. This attempts to build a clearer miai of doing one job or another well intead of a bit of either poorly: either get the bottom group out with style by aiming at the k3 push and 2 cuts weaknesses, or get some forcing/inducing moves out of it and net the centre cutting stones. For example if white pushes through:
