The registration deadline for the World Pair Go Tournament has been extended to this Thursday at midnight. Recognizing the World Pair Go Tournament as a special one-time celebration of the 20th anniversary of the creation of Pair Go, the AGA Board Sunday night voted to waive both the one-year continuous membership requirement and the 10-game minimum requirement for the qualification tournament, as it had waived some requirements for the World Mind Sports Games last year under similar circumstances. U.S. citizenship and U.S. residency for at least six of the past twelve months still are required. Interested pros and amateurs must contact President@usgo.org with names and AGA ID’s by the deadline

Gu Li Winningest Pro In ’09
Monday February 1, 2010
An important indication of superiority among go professionals is their winning percentage, especially among the most active players. Here is a rundown for 2009. Gu Li 9P of China was the player with the most wins in international events, winning eighteen and losing seven for a winning rate of 72%. Second in number of wins was fellow Chinese Qiu Jun 9P with 17-8 for a 68% rate. Third was Heo Yeongho 6P of Korea whose 16-4 record gave him an amazing 80% win rate. Not surprisingly, the top twenty international event winners are all either Chinese (9) or Korean (12): nine Chinese and twelve Koreans (a six-way tie for 16th makes the total twenty-one).
In 2008, Gu Li was third behind Lee Sedol 9P and Lee Changho 9P of Korea, but Gu’s winning percentage was higher: 82% vs. 75% and 74%.
In Japan in 2009 Iyama Yuta 9P was dominant, not only winning the most games (43-14) but also having the highest winning percentage among the top winners: 75%.
Yuki Satoshi 9P was second in wins, 40-15.
Top title holder Cho U 9P fell to fifth place, winning 35 while losing 19 for a 65% rate. Cho was the top winner in 2008 in Japan.
In Korea, Kim Jisuk 6P, who turned twenty during 2009, was the top winner at 71-20 for a 78% rate. His 78% winning percentage was also top among the thirty players with the most wins.
Choi Cheolhan 9p was second on the winning list with 56-18 for a 76% rate, and Lee Changho 9P was third with 50 wins and a 66% rate.
Lee Changho was second in 2008 behind Lee Sedol 9P (who is currently not playing in professional events).
Kong Jie 9P is the top winner for 2009 in China: 47-20 for a 70% rate.
Only one player among the top thirty winners in China has a higher rate: Tan Xiao 5P in fifteenth place with a 74% rate for 33-12.
The precocious teen Chen Yaoye 9P – who turned twenty at the end of 2009 — was second in China with 46-20, which also gives him a 70% win rate.

Monday January 25, 2010
JAPANESE SURGE IN THE NONGSHIM CUP: The Japanese, who in recent years haven’t survived past the second round of the Nongshim Cup have made it through to the third round this year.

The Koreans started out strong as usual, when Kim Jiseok 6P won the first three games, defeating two Japanese: Yamashita Keigo 9P and Takao Shinji 9P. Then Xie He 7P of China took over, winning five games before being stopped by Hane. The Koreans are also down to a single player, Lee Changho 9P, while the Chinese still have three. Hane’s next game will be against Liu Xing 7P of China in early March. The other Chinese players are Chang Hao9P and Gu Li 9P. Sources: Go News, GoGameWorld, Sensei’s Library, JustPlayGo
WORLD GO NEWS: Korean Teen Park Junghwan Wins Third Title Match; Iyama Yuta Takes Clear Lead In Honinbo League
Monday January 11, 2010
KOREAN TEEN PARK JUNGHWAN WINS THIRD TITLE MATCH: Park Junghwan 5P (l) won’t be twenty until 2013, but he is already becoming a major player. Last year he won two Korean titles, the Siptan (Judan) Cup and the Chunwon (Tengen), and he has just successfully defended the Sibdang against challenger Lee Changho 9P with a score of 2-1. Lee won the first game of the match, but Park took the other two on January 9th and 10th. In the unusual structure of the Siptan, as last year’s winner, Park was seeded into the third round, so he had to win two games just to get into the title match.
IYAMA YUTA TAKES CLEAR LEAD IN HONINBO LEAGUE: In the eight-player round robin league to decide the next challenger for the Honinbo title in Japan, Meijin Iyama Yuta 9P has a 4-0 record with three games to go. Everyone else has at least one defeat. The closest competitor at this point is Yamashita Keigo 9P with a 3-1 record. He and Iyama have not yet met in the league. Yamashita currently holds both the Kisei and the Tengen titles. Iyama is Meijin and also won the Ryusei last year.

CHINA WINS 7TH JAPAN-CHINA AGON CUP: Sun Tengyu 4P of China defeated Japan’s Hane Haoki 9P by 3.5 points on December 9th to win this year’s Japan-China Agon Cup. The match between the winners of the Japanese and the Chinese Agon Cup tournaments has been a painful experience for the Japanese lately, as the Chinese Cup holders have now won seven straight matches. Sun is a teen whose only title before winning the Chinese version of the Agon Cup (Ahan Tongshan Cup) this year was the National Individual championship in 2008. Hane is in his thirties and has been a major player on the Japanese pro scene. He is the current Honinbo and held the number one Japanese title, the Kisei, in both 2004 and 2005. In the Chinese event, Sun defeated both Gu Li, China’s current top title holder, and Piao Wenyao 5P, another of the strong young Chinese pros. – Bill Cobb, from Go News, GoGameWorld

DAVIS WINS 2ND IRISH CHAMPIONSHIP: Ian Davis beat Claas Roever 2-1 (date) to take the 2009 Irish Championship title. The championship came down to a final, tense game, “As usual between these two it was a game that could have gone either way,” reported Stephen (last name) on the Irish Go Association website. “After repeating the opening of the second game, Claas took an early lead by switching to a Gibson style strategy using some risky opening plays. However somewhere in the middlegame he lost his way, and Ian forced resignation after a devious invasion.” This was Davis’ second Irish title; he has another 14 wins to pass all time Irish title record holder Noel Mitchell. Davis, President of the Irish Go Association and Irish Correspondent for the E-Journal, credited altitude training in County Donegal for his win. Click here for the record of the final game.
