Interesting opinion of O Rissei

Post by macelee »

O Rissei 9-dan is a Nihon Kiin player with Taiwan origin. He was recently interviewed by a Taiwan media, in which he said:

目前日本、中國和韓國頂尖棋手實力差不多,若番棋較量還是看好井山裕太

My translation:

Nowadays the strength of top Japanese, Chinese and Korean players are about the same. In multiple-game matches, I have faith in Iyama Yuta.

I am wondering if this is just his personal opinion or might this be a representative view among Japanese players.

BTW, O Rissei was there commenting a game from Taiwan Qiwang tournament. The game has a hoshi + 3-3 + tengen opening at the beginning and an interesting L&D problem in the end.

How do we know that he was not being anything but diplomatic? :)

It's hard to agree with that opinion when the Top 100 in the world consist mostly of Chinese and Korean players.

Converted to histogram format, goratings' list sorted by country looks a bit like this:

Can Iyama Yuta, Yamashita Keigo, Kono Rin, Yuki Satoshi, Ichiriki Ryo and Takao Shinji compete with the best of the others?
If only they played more international games,...

The problem with Japanese go isn't the top (i.e. Iyama). It's the fact that Iyama is literally alone at the top; there is a huge disparity in skill level between him and every other Japanese player. His record against title challengers makes his dominance clear. I think Iyama could compete with anyone in the world in a multi-game match, though I'd give a slight edge to some of the other top players. No one else in Japan can even get decent results in a multiple game match with Iyama.

Has everyone seen the games between Iyama Yuta and Park Jeong-hwan in the final of the 25th Asia Cup final?

A thrilling game. There are subtitles for the commentary, though it looks like machine translation.

This year, yes, but last year he lost a title match to Murukawa and Takao.

It is a bit tricky for us but pros have no difficult to read through.

First, note that black cannot lose any of the two marked stone.

If white plays :w1:, :b2: is sente. Then Black can get either 'a' or 'b' to capture some stones to create his second eye.

So :w1: is a must. Black :b2: and :b4: are good, reducing white's liberty. Then black can separate white's group at :b6:.:b8: is also an important move to reduce one liberty further. Now it is a good exercise that white cannot capture the two marked stones. In fact if white tries, he will be short of one liberty.

that position, isn't the white center group dead? i see no way for white to capture anything, and it only has 5 liberties, where as black has more than 5.

Exactly, that's why white resigned.
