Cho U Defends Gosei Title

Tuesday, July 21st, 2009
Cho U won the third game as well against challenger Yuki Satoshi and defended his Gosei title with straight wins, 3:0.
Gosei Title 2009, game 3
Yuki, playing white, started with an unusual opening again (his 4th move was on the 4X6 point!) but lost in the end by 1.5 points.

The game record is here.

Cho holds 5 of the 7 major Japanese title. I wonder if he will become Kisei challenger – he started the league well, 2:0, but it is way too early to know for now.

Hane captured this title from the same Takao last year, in a dramatic finale: Takao was leading the titile match 3:0 when Hane won the 4 remaining games.

Game of Go Mentioned in Investment Article

Monday, July 13th, 2009
I just found a mentioning of the game of Go in an investment article. Here is the relevant quotation from the article (it’s form the second page):
At a recent conference in south Florida economist Ed Yardeni opined: “America is trying to figure out how to provide free everything for its citizens, while China is trying to figure out how to get its next million barrels of oil!” Adding to that was Jeff Saut, another 40-year market veteran: “Indeed, while America is playing Texas Hold’em (aka, play one hand at a time), the Chinese are playing the game GO. In the strategic game of GO, a player sacrifices numerous “pieces” in the short-run to “win” in the long-run.” GO is a 2,500-year-old game where one of the most important skills required for strong play is the ability to read ahead. Some claimed that GO is the most complex game in the world due to its vast number of variations. Plays made early in the game can shape the nature of conflict a hundred moves later. GO sounds similar to investing to me.

Gosei Title: Cho U Won Game 2, Leads 2:0

Friday, July 10th, 2009

Cho U, title-holder, defeated Gosei challenger Yuki Satoshi by 13.5 points in the second game of the title match. Cho U won the first game as well, and since Gosei has a best-of-five system, he needs only one more win to keep the title.

Cho U, Gosei title 2009, game 2

Yuki Satoshi has a very interesting style: his openings are quite non-standard, which leads to interesting games with many fights – this one makes no exception.

The result, 13.5 points difference, is unusual: professional players usually resign when the difference is larger than 5 points, but there are some cases when games are played till the end for various reasons:

  1. When in time-trouble and with lots of exchanges happening late in the game, one may simply not be able to count accurately.
  2. When one doesn’t find “the proper time to resign”, games usually continue till the very end.
  3. When one doesn’t feel like resigning. :-)

Historically, Sakata Eio, one of the most famous professional players in Japan, was well-known for playing till the very end even in games where we lost by over 20 points difference.

The third game will be played on July 21st.

Kang Dongyun Defeats Lee Changho in Fujitsu Cup Final

Monday, July 6th, 2009

Kang Dongyun, playing white, won by 2.5p against Lee Changho, thus winning this year’s Fujitsu Cup, one of the top international tournaments.

This seems to be Kang Dongyun’s first international win.

You can read an older interview with him, translated from Korean by Alexander Dinerchtein, here.

Fujitsu Cup: All Korean Final

Saturday, July 4th, 2009

The international Fujitsu Cup semifinals took place in Tokyo, Japan, with three players from South Korea and one from China.

The last Japanese players were eliminated in the quarter-finals, when Kono Rin had lost to Park Yeonghun and Yamashita Keigo had lost to Lee Changho.

The last year winner, Gu Li of China, and the player with the best international results during the past year, was eliminated earlier by Kono Rin.

In one semifinal Lee Changho took revenge from Chang Hao, to whom he lost Chunlan Cup final by two straight losses, and won by 4.5 points.

Game record is here. Lee Changho made use of some very interesting ladder-break – see move 20. It looks like modern Go is more and more open, and there are less and less “sacred cows” as far as good-bad shapes go, or as far as “not supposed to play this way” situations go.


In the other semifinal, Kang Dongyun defeated Park Yeonghun by resignation.

Here is the game record.

The one-game final between the two South Korea finalists, Lee Changho and Kang Dongyun, will be played on July 6th in Tokyo, Japan since Fujistsu, the sponsor of this tournament, is a Japanese company.
