Again 19 new games, even though this time it was only 2.5 month ago that I updated this site.

Is Cho performing a come back? He was certainly doing well in the Kisei, with winning the B group he is only one win away from playing in the final match! However his opponent in that game between the winners of the A and B group is the formidable Cho U, and Cho Chikun has not won a single game against him in the last four years. So we will see -- the game is not yet scheduled but should be played soon.

Another success is that Cho Chikun entered the Meijin League again.


Cho Chikun

The major part of this site is a collection of games by Cho Chikun. Cho, Korean by birth, became one of the greatest go players of Japan in the 20th century. Even though he won his 68th title in 2005, his performance the last couple of years has been a bit of a disappointement for his fans.

I have over 1750 records of professional games that he played, but this site does not just give you the games. It also gives a comprehensive biography, nearly 300 pages of indexes per opponent, tournament, year and other related information. It is probably the largest (freely available) collection of games of a single professional go player on the web. There are two ways to start your discovery tour through this collection:


Korean TV games

Since my trip to Korea in 2003 I have gotten much more interested in Baduk (the Korean name for go). After I discovered that I could see the broadcasts of KBS Satellite TV and of Baduk TV (바둑 TV) I went through many game records from recent Korean tournaments. A new addiction? Well not that much, because this part has not been updated for several years :-(


Hikaru no Go

Hikaru no Go was a very popular manga (Japanese comic) that ended in the middle of 2003. In the series the boy Hikaru learns how to play go from a ghost (Sai). It is a very interesting story about loyalty (to Sai), rivalry and growing up. In the end of the series Hikaru is a young professional go player.

Almost all the games that appear in the manga are real professional games. It was great fun trying to find them. And even though this part of the site is almost "dead", it is still the most popular part with visitors.

Umezawa Yukari was the advisor to Hikaru no Go. I met her in September 1999. Maybe that was why I might appear in Hikaru no Go as Mr Ooijer?

About this site

This site is about go (Japanese: 囲碁 ), a board game of oriental origin. Over the years I collected many games of professional go players that you can find here. It is still maintained regularly (on Friday nights), although not as frequent as in the past. You can download everything for free for your own use from here, but please read the copyright statement at the bottom of this page if you want to distribute anything further.


The site has been redesigned. All the links must work, although some of the older stuff is not (yet) converted. For some of the frustrations getting this right, see the about page.  [2004-08-13]
