Some Go Softwares

These are some go softwares that I have tried:

I think MultiGo is one of the best go software. It is light (1.6Mb) and can open all (so far as I know) go format. It can open the usual .sgf and game format from IGS and CyberOro (which is not .SGF) and more formats.

Drago is a very good software. It has database function where you can put many games and then using kombilo to find pattern that you want. Very good for reviewing your games

TurboGo is a go software with joseki database which I find very handy to used for either begginner and advance players. It also has a screen saver function. The only problem that I know is that it's a trial program. You can use it whenever the trial has end, but you will need to wait several minutes, before it starts.

WinHonte is a software that I used very much when I started playing go. It is also featured by 6 level AI (Artificial Intelligent). But since it's a trial version, level 2 and above only featured in the first 100 moves, and then it'll change to level 1 after that.

Damezumari Trouble.

Do you know what a ダメ詰まり ( damezumari ) is? Damezumari (also known as 수부족,subujok) is an igo term, means shortage of liberty.

An example of damezumari

Sometimes, damezumari can be really tricky. When someone think that one group is alive, be aware of damezumari.

Here's some example of damezumari mistake:
A mistake of damezumari by Yashiro Kumiko.
A mistake by Nakano Yasuhiro.

I remember that in Hikaru no Go, Tsutsui won from Kaio player, due to a misread of damezumari by the Kaio player, but I ndon't know the game record.

Umezawa Yukari Defend Female Kisei

After lost the second game, Umezawa Yukari, Female Kisei, won the third game along with the title.

The third game is fiercer than the second game. In the early stage, Umezawa's weak group was attacked. Umezawa Yukari made an eye shape with sacrificing three stones at move 77. But the group wasn't yet alive. The battle continued with a ko fight started at move 110. This ko fight was very important for Umezawa. She must won this ko, or she'll lost two groups of stones.
At move 120, Umezawa finally can save one of her group. winning the ko by capturing 2 stones with J19. But one of her cluster is not yet alive. At the same time, the game was not easy for Kato Keiko. Letting Umezawa to save one group, she chased the big cluster by putting her group into danger and fight for the second ko at L19. A kill or killed ko.

board position up to move 105

Fifty two moves later, Umezawa won the ko and killed Kato's group. Kato Keiko resigned at move 286. White's leading was obvious. Umezawa Yukari was leading about 10 points on he board.

With this victory, Umezawa Yukari already hold the title for the last 3 years. She took the title 3 years ago from Mannami Kana. Female Kisei is the only title Umezawa Yukari ever has and the only big title where she was ever become the challenger.

Kato Keiko Closed the Gap

Kato Keiko, the challenger of the 12th Female Kisei sen, won the second match by the same margin as her lost in first match. Kato won by 2.5 points.
The game was quite well spirited. A fight started in early stage. Kato Keiko chose to attack Umezawa's weak group in the right. Umezawa's cut at move 32 was brave, since her attacked group was not yet settle. The fight spreaded to center.

Umezawa Yukari (W) vs. Kato Keiko (B), game up to move 70

I think the outcome of the battle was favourable for black, since she gained sente at the beginning of the yose stage.
