By goratings elo, Ichikiri Ryo had a 39% chance to beat Fan Yunruo. Not a huge upset, but he wasn't favored.

He has 51% against Min Sangyoun; they are 9 elo apart. If he does win 3 in a row it will be the best result by a Japanese pro in the Nongshim cup since Yoda Norimoto won 3 games way back in 2006 (I think).

And with that, they've matched last year's win count without yet losing a single player.

I like Ichiriki's style, lots of intricate close fighting and interesting shapes.

From today's game: white 1 has to give up killing the dragon. Can you see why?

Mimura Tomoyasu from Japan said this in his twitter which I found interesting.

"一力七段の碁を見ると強気に仕掛けて戦い抜いて勝っている。このスタイルは特に団体勝ち抜き戦ではプラスに働くと思う。"
He's commenting that Ichiriki's style of Go is winning with strong fighting skills. This style is especially useful in a win through group style tournament.

I don't know exactly why he thinks that way, but I thought it was interesting anyway.

Through Google translate for fun
"If you look at the go of Ichi-ryoku seven stages are won by fought by bullish gimmick. I think this style work plus, especially in group tournament."

However, maybe white doesn't need to cut (and the consequent liberty problems that creates) but can let black connect and try to kill the whole thing. Harder to read what will happen as black searches for an eye or some capture in the centre, but there's probably enough aji to do something

This makes me wonder though about white's reasoning when he played the hane on the left. Was this a serious attempt to kill and he hadn't seen black's escape? Because in terms of points he lost a lot here and surely there was some better way of playing some move in the sente like L8 that white would have to ignore or answer passively to avoid dying and then once black makes his gote second eye white gets 2 moves in the centre.

He's commenting that Ichiriki's style of Go is winning with strong fighting skills. This style is especially useful in a win through group style tournament.
Thanks for spotting that comment.

Incidentally, is this 'win through' an Americanism I haven't come across yet, or is it your own rendering? I would call it a "win & continue2 team tournament. That was my own rendering, but it seems to have acquired a fair degree of acceptance.

But back to the very interesting comment. I would have thought that the bullish challenges followed by all-out fighting that Mimura describes would be useful in all international events, not just team ones, so I'm a little surprised he didn't go that far. At the same time, there seems to be a hint that it's maybe not so useful back in Japan. Which may be the case, but I suppose we could also argue that Mimura (approaching 60) is one of the old guard that haven't quite got the feel of this new style.

We have to be careful of how much, and what, we read into such comments. The main differences that I see between the Nongshim Cup and, say, the knockout preliminaries to every Japanese tournament that Mimura's readers would be more familiar with, are that: 1. only one game is played at a time so the spotlight is very much on the players of that game (expect lots of kiai) and 2. you do not know who your opponent will be until the day before (and they are unfamiliar even then) so you have limited ability to prepare based on past experience with that opponent.

Also of course, Mimura is writing to make sense out of Ichiriki's success. If Ichikiki gets trounced next time, let's see whether Mimura writes about how he failed to stay true to his 'successful' approach in games 1-3. :)

Ichiriki Ryo's good fortune came to a very abrupt end. By that I mean he appeared to be doing fine but all of a sudden resigned. It took me about 20 minutes to understand why he had to resign.
