New joseki analysis

Saturday, February 16th, 2008
I wrote a brief analysis on this new move:

New joseki

(Link to the article) I saw this move for the first time in the Takemiya Masaki – Yamada Takuji game that I already wrote a blog entry about.

Two unusual moves

Wednesday, February 13th, 2008
I followed a live game on Cyberoro: Takemiya Masaki 9p against Yamada Takuji 7p. Yamada was an A-class insei when I became insei in Japan, then he soon won the pro qualification. We both lived in the “Igo Kenshu Center” (Go study center) for a while (so did Kato Keiko who is currently defending her Meijin title against Xie Yimin).

Yamda Takuji

Yamada played 2 unusual moves against Takemiya in the beginning of the game. First White 8 is unusual (normally White plays hane below Black 7):

Then look at White 38: tsuke against the hoshi stone!

I guess somebody was in a quite inspired mood :-) It payed off for Yamada, since he won the game by 2.5 points. Link to complete game record.

Teaching game with Kato Masao

Sunday, February 10th, 2008

I wrote a new article: Teaching game with Kato Masao. It is based on a 3-stones handicap teaching game I received from Kato Masao 9p back in 1990 when I was 3 dan and I represented Romania at the WAGC.

What motivated me to write the article at this point was the godiscussions.com thread “Asking professionals for serious games” – in particular Tommie’s request there.

I hope you enjoy it!

The 10 rules of territory in Go

Friday, February 8th, 2008
Here’s how to think about territory in Go:
  1. If I like it, it’s mine.
  2. If it’s in my hand, it’s mine.
  3. If I can take it from you, it’s mine.
  4. If I had it a little while ago, it’s mine.
  5. If it’s mine, it must NEVER appear to be yours in anyway.
  6. If I’m doing or building something, all the pieces are mine.
  7. If it looks just like mine, it is mine.
  8. If I saw it first, it’s mine.
  9. If you are playing with something and you put it down, it automatically becomes mine.
  10. If it’s broken, it’s yours.
(Strangely similar to the Toddler’s Rules of Possession)

Kisei game 3: Yamashita forces Cho to resign

Friday, February 8th, 2008
Yamashita takes the lead again (2-1) after game 3: he forced Cho to resign.

Yamashita Keigo - 2008

The game started strangely, with a big fight on the left half of the board, while the right half was almost empty (the forth corner was occupied only on move 70!). Apparently Yamashita had the upper hand when the dust settled on the left side, which prompted Cho to try his last chance by building a huge moyo in the upper right and then threatening to kill Yamashita’s invasion – but that didn’t work.

Added handicap to the computer-go interface

Thursday, February 7th, 2008

I added the possibility to play with handicap against the GnuGo computer-Go program, online. This should make games more interesting. Link to computer-Go page here.

Also, I owe an apology: I have introduced a bug that resulted in the board not to be displayed at all for the InternetExplorer users for the last few days. Fixed now. (By the way, why not use Firefox instead of InternetExplorer?)

This is a high-tech variation of the previous “No goban? No problem!” blog entry.

Lee Changho Returns

Saturday, February 2nd, 2008
After a period when we didn’t hear much about him, Lee Changho seems to be coming back in top form: he won the Korean Siptan (10 dan) title against Mok Jinseok 2-0. (Games here and here.)

Lee also has a 13-0 score in 2008 so far (February 2nd, 2008), according to Go Topics!
