Rengo rules at Seattle Go Center

Tuesday June 12, 2018

Rengo/Pair Go events are consistently popular at the Seattle Go Center, and last Saturday was no exception. Twenty-eight2018.06.12_seattle-pairgo-round-one-600x450 players — fourteen teams of two — competed in the “Rengo with Pie and Coffee” tournament on June 9, organized by Pair Go stalwart Bill Thompson, who brought the fancy pies (strawberry-rhubarb, coconut, wild cherry, and apple), directed the tournament, and even played in it.

The event was run with the International Pair Go Association rules, but with no restrictions to team composition. Thompson used a spreadsheet from longtime Pair Go tournament director Todd Heidenreich to calculate the teams’ handicaps and komi, averaging the individual ratings of the team members.

Time limits were 45 minutes absolute (no byo-yomi). The players at Table 1 had competitive spirt — one of their games finished with 9 seconds on 2018.06.12_seattle-pairgo-table-winners-600x451the clock for Black, and 6 seconds left for White; and another of their games ended in a tie.

Undefeated after two rounds:
Table 1: Lusha Zhou (9k) and Tzu-Jen Chan (3d) (in back).
Table 2: Yulissa Wu Lu (10k) and Lucas Wu Lu (9k) (front center).
Table 3: Hotaka Ozaki (3k) (at far left) and Abigail Chen (20k) (front far right).
Table 4: Joshua Yang (11k) and Shirley Yang (30k) (not pictured).

More pictures will be posted soon on the SeattleGo website.

Reflections on Pair Go

Wednesday February 22, 2017

by Eric Lui 1P2017.02.22_A Simple Guide to Pair Go

Editor’s note: Lui, who’s now a regular game commentator for the E-Journal, wrote this after attending the second Pair Go World Cup in July 2016 and recently shared it with us. Coincidentally, Hajin Lee recently made a short Pair Go introduction video, saying she hopes “to see more pair go events in the US and Europe in the future.” We hope you enjoy both.

Reflecting upon his legendary career, the great Sakata Eio opined that a necessary prerequisite for go mastery is self-2017.02.22_pair-go-world-cup-411_sreliance, which can only be developed once one fully accepts the game’s solitary nature, specifically the completely isolated state that all players find themselves in during the process of a game.

As far as I can tell, there are two types of people in this world: Pair Go enthusiasts and those who can do without. Takemiya Masaki gushes that Pair Go is “playing catch with the emotions…the instant that love is born.” Ishida Yoshio, on the other hand, says that in Pair Go you have three opponents.

The most anticipated match in the first round of the main knockout tournament saw the departure of powerhouse 2017.02.22_pair-go-world-cupChinese pair Shi Yue and Wang Chenxing, who succumbed to the charming synergy of Choi Cheolhan and Oh Yujin. Our first-round victory against the Thai pair was defined more by relief than pleasure, since it ensured that we would get to play at least one more game. In the second round against Taiwanese superstars Chen Shiyuan and Joanne Missingham, the game became difficult right from the start when a mistake in judgment set the tone for the rest of the way. My partner Sarah Yu fought gamely during many continuous kos and we maintained our chances for a while but were unable to cause an upset.

Our conquerors would go on to score an excellent victory in the semifinal against the Choi-Oh pair, earning themselves a 2017.02.22_lui-pair-gofinal showdown with the Chinese pair of Ke Jie and Yu Zhiying, the male and female world No. 1 respectively.
During the last round of the Shuffle Pair Go friendship match, I was paired with the Thai female player, Pattraporn Aroonphaichitra. As we waited at the board for our opponents, Amy Song, the Australian female player took the seat across from Pattraporn. But who was her partner? I took a quick glance around – there were still a few empty seats and just a couple minutes until game time. I couldn’t help but smile when I noticed Sarah, looking ever so serene, sitting next to Iyama Yuta. My new partner was completely absorbed in her phone, and I opened my mouth to say something when, sensing a disturbance in the Force, we both looked up. Making his way through the large crowd that had gathered around the closed-off playing area with ruthless efficiency was “One Dragon Per Game” Shi Yue, one of the strongest and most universally feared Chinese pros for his aggressive playing style.

2017.02.21_pair-go-eric-luiPattraporn played beautifully and we enjoyed a lead for most of the game. It was a singular experience to watch as Shi Yue struggled to contain his frustration with the position as his plans to deal us pain were disrupted again and again. When the game was over, Shi Yue transitioned seamlessly from executioner to teacher, pointing out missed opportunities and explaining his thought processes at key points while the rest of us sat transfixed by the clarity of his analysis. A while later, only dimly aware that the postmortem had concluded and that the others had started putting the stones away, I slowly and reluctantly joined in.

Later that night, long after Yu Zhiying and Ke Jie had collected their 10 million yen 1st place prize, I would find myself tuning in to the Wimbledon final from my hotel room. During one of Andy Murray’s signature tirades, I realized that Ishida was wrong. Whether you are playing Pair Go, individual go, or tennis, the number of opponents remains the same. One, and it’s not the one on the other side. As Murray sealed the first set with a thunderous forehand and an emphatic fist pump, his fierce visage betraying equal parts triumph and anguish, I was reminded of a timeless image of Sakata, in the midst of his prime, staring at the go board with an expression of utmost intensity and exquisite pain. A formidable, yet lone individual.

Pair Go was invented to popularize the game of go by emphasizing the social aspects of the game. But no matter how many players there are, the game itself remains the same mysterious, fascinating challenge it has been for thousands of years.

Kim Sooyoung and Park Jongwook of Korea Win Amateur Pair Go Championship

Sunday December 4, 2016

A Korean pair won this year’s 27th International Amateur Pair Go Championship in Tokyo, besting a Taiwanese team in the 2016.12.04_us-pairfinals.  Kim Sooyoung and Park Jongwook of Korea beat Pai Shin-Hui and Huang Wei of Taiwan.  Pai and Huang had paved the way, however, by beating a strong Chinese pair in round one of the 32-pair five round event.  The US team of Jeremy Chiu and Gabriella Su (right) ended with a solid 3-2 record, losing in rounds one and three to a Japanese pair and the team from China, but beating Germany and Austria before facing a strong Russian pair, Grigorii Fionin and Elvina Kalsberg, also 2-2, in the final round.  In the 3rd edition of the World Students Pair Go Championship, North American pair Amira Song of Canada and Andrew Zalesak of North Carolina went 1-3, beating the Mexican pair but failing to beat the percentages in their other games against a Japanese pair and not one, but two, Korean university pairs.  A Japanese pair took first.

Chen and Cao Top Youth Adult Pair Go

Thursday August 4, 2016

IMG_20160802_132911Michael Chen 8d and Melissa Cao 4d won the top table at Youth Adult Pair Go on Tuesday at the Go Congress.  The event was a big hit with both young and old, drawing 56 players to the Youth Room. Seven tables competed, with first and second place at each table winning prizes, including go books donated by several publishers, Hikaru no Go manga, and several new sets of various anime series donated by Winston Jen. Devin Fraze has taken over in the Youth Room this year,  allowing longtime organizer Paul Barchilon to actually play in the event,  pictured below with his partner, 5 year old Tselmuun Ganbaatar (who was violating all known standards of Pair Go rules and etiquette by telling her partner how it important it was for him to play where she told him). Every table saw exciting games, many with giggling kids – and astonished adults as the kids outplayed everyone nonetheless. Other events in the Youth Room included lightning go on Sunday, 9×9 and 13×13 tourneys on Monday, and relay go on Thursday.  One youngster said he enjoyed relay go the most, because he “really likes to run.” Fraze, whose day job is teaching fifth grade, was clearly up to the challenge of managing so many kids at once.

IMG_20160802_132501Winners Report: Table one: 1st place: Michael Chen 8d and Melissa Cao 4d,  2nd place: Daniel Liu 6d and Jinli Wang 6d; Table two: 1st place: Frederick Bao 3d and Sai Sun 5d, 2nd place: Kelly Liu 2d and Yunbo Yi 6d; Table three: 1st place: Yungyan Wu 1k and Tao Wu 1d; Table four: 1st place: Owen Sedgwick 12k and Irene Sha 6d; Table five: 1st place: Liya Luk 9k and Allen Noe 1k; Table six 1st place: Sarah Crites 10k and Bob Crites 7k; Table seven: 1st place Zoey Zhang 30k and Yunzhe Zhang 6d.
