The Power Report: Fujisawa makes good start in Women’s Honinbo; Iyama close to goal in Meijin title match, but Cho picks up second win; Honinbo League

Sunday October 21, 2018

Fujisawa makes good start in Women’s Honinbo: For the fourth year in a row, we have the same pairing in the Women’s Honinbo title match, that is, Xie Yimin v. Fujisawa Rina, but alternating the roles of defender and challenger. Fujisawa first won the title in the 33rd term (2014), when she beat the defending champion Mukai Chiaki 3-0. The following term, Xie, who had already won this title six times (in a row before losing to Mukai), challenged and regained the title with a 3-2 score. In the 35th term, Fujisawa took the title back, winning 3-1, but lost it to Xie 2-3 the next year. So it was no surprise when Fujisawa became the challenger again this year for the 37th term. At present, this is the only title Xie has, so she will be reluctant to hand it over. If Fujisawa wins, she will become a triple title-holder again, as she also has the Hollyhock Cup and the Women’s Meijin. Incidentally, this is the third time that a women’s title match has featured the same card four years in a row; it has not yet happened in open tournaments.
The first game was held at the Kashoen inn in Hanamaki City, Iwate Prefecture, on October 10. Taking black, Fujisawa won by resignation after 145 moves. Xie is known for her aggressive style, but in the early middle game she played a move focused more on defending one of her weak groups instead of attacking, and this seems to have made the game tough for her. Later, she played another overly defensive move, letting her opponent occupy the last remaining big point from the opening. Xie staked her chances of pulling off an upset on setting up a center moyo, but Fujisawa was able to whittle it down enough to keep her lead. There is a long gap before the second game, scheduled for November 9. Incidentally, Fujisawa has been on a winning streak since August 30, and this was her ninth successive win.2018.10.21_43meijin4 Iyama R

Iyama close to goal in Meijin title match, but Cho picks up second win: After Cho U scored a good win in the third game of the 43rd Meijin title match, it looked as if the contest was going to heat up. Ishida Yoshio, 24th Honinbo, often comments that the fourth game in a best-of-seven is crucial, as there’s a big difference between 2-2 and 3-1. The all-important fourth game was played at the Takarazuka Hotel in Takarazuka City, Hyogo Prefecture, on October 10 and 11. The first day’s play, which showed strong AI influence in the josekis, was quite promising for Cho, who had black. However, he went wrong on the second day when he made a strategic decision that took territory but gave Iyama too much central moyo potential. The defending champion took the initiative. Cho had to invade Iyama’s moyo, but was unable to live with all of his stones. Iyama cut off what in the end was nearly half of the invading force, and this was enough to win. Cho resigned after 188 moves. That took Iyama’s lead to 3-1, so he is very close to defending his title.
The fifth game at the Tokiwa Hotel in Kofu City, Yamanashi Prefecture, on October 15 and 16. Playing white, Cho won by 9.5 points after 284 moves. This keeps his challenge alive, though Iyama still has an edge. The sixth game will be played on October 22 and 23. (I will give more details about the game in my next report.)2018.10.21_Honinbo

Honinbo League: Two games have been played in the new Honinbo League, the 74th. On October 4, league veteran Hane Naoki 9P (W) beat league debutant Anzai Nobuaki 7P by resignation. The second game was played on the 11th, with Yo Seiki (Yu Zhengqi) 7P (W) beating Yamashita Keigo 9P by half a point.

Promotion: To 9-dan: Kim Sujun (200 wins, as of October 12)

Mark Lee 7d sweeps to win 4th Cotsen Open title

Sunday October 14, 2018

As expected, the key game determining the 2018 Cotsen Open winner was Round 4 on Sunday morning, when defending 2018.10.14_lee-sweeps-cotsenchampion Mark Lee 7d faced Andy Liu 1P, both 3-0. The two players wasted no time getting down to business, beginning playing while the room was still bustling with noisy players finding their seats. The opening played out very quickly, with Liu taking cash and 2018.10.14_liu-leeLee sketching out a large moyo. Liu’s AlphaGo-like move 45, adjacent to the center star point on the very edge of Lee’s right-side moyo, set the tone for the rest of the game, as Lee fiercely attacked Liu’s eyeless dragon and the fighting got ever more complicated as ladders and nets spiraled out across the board (see game record, below). As more than 130 viewers on KGS hotly debated whether Liu’s group would survive, the players moved into an extended and complex endgame battle for sente and the handful of points that would secure a victory, and the championship. In the end, Lee’s endgame tesujis prevailed and Liu resigned, a few points behind on the board, plus komi. “Andy’s very strong,” Lee said, “it was a tough game.” Liu returned the compliment, saying that Lee “played well; it was really a great game.” Lee went on to win the final round against Luan Bo 6d to complete his 5-0 sweep and collect his fourth consecutive Cotsen Open championship. “We may need to re-name this the Mark Lee title,” joked Eric Cotsen, who thanked all the players for turning out for the 29th annual tournament. “You’re what makes this event so special.”

Seattle 23rd Anniversary Tournament

Sunday October 14, 2018

To celebrate its 23rd anniversary, the Seattle Go Center held a 3-round tournament on Sunday, October 7. Notably, among the2018.10.13-Seattle-Anniversary-Tournament-2018-smaller 32 players in attendance, “a quarter have AGA youth memberships,” reports Seattle Go Center Programs Manager Mike Malveaux. Tournament Director Bill Chiles “handled clock malfunctions and consequent pairing delays with aplomb,” Malveaux adds, “and Daniel Top stepped in smoothly to render assistance.” Thanks to the generous assistance of the Seattle AGA Chapter and the AGA Chapter Rewards program, Malveaux reports that six large pizzas were demolished between the first and second rounds.

The “Open” section was limited to eight players vying for the top prize of $150 cash, won by Alex Xinlei Liu 7d with a 3-0 record.  Liu has been a strong contender at Seattle tournaments, winning the Seattle Go Center Spring Tournament Open in 2017. 

The twenty-four players in the “Handicap” section all had games with handicaps of three stones or fewer, and all but two games were at two stones or less.  “Handicap” players who won all three of their games were awarded prizes of go books and equipment.  In addition, there was a cash prize for the under-18 youth player with the best win-loss record, which was divided among three young players who went undefeated.

Open Section 3-game winner: Alex Xinlei Liu (7 dan)
Handicap Section 3-game winners: Yao Zhihong (2 dan), Chen Xiangnan (3 kyu), Frank Brown (6 kyu), Lucas Wu Lu (9 kyu), George Schmitten (9 kyu), Yulissa Wu Lu (10 kyu), Amy Ling (15 kyu)
