The Power Report: Ida takes lead in Judan; Ko Iso leads Meijin League; Quadruple ko; LG Challengers Cup

Monday April 13, 2015

Ida takes lead in Judan: The second game of the 53rd Judan title match was held at the Kuroyon Royal Hotel in the city of Omachi in Nagano Prefecture on April 9. Omachi has become closely linked with the Judan tournament: this is the 22nd year in a row that a game from the title match game has been staged here. Omachi is a gateway to the Northern Alps and it has sought to establish itself as “the Alps go village.” Four years ago, Ida Atsushi was the game recorder for the Judan game held here and now he was playing in the title match, challenging Takao Shinji (right). 
        The game started with fierce fighting, and the first notable move was a move by Ida, playing black, that defied a go proverb by letting the opponent drive a wedge through some neighbouring stones (the proverb is, “don’t let yourself be split into two”). Despite this, Ida got off to a reasonable start. In the middle-game fighting, Ida took a small lead and managed to hold on to it to the end. He won by 2.5 points after 277 moves. After making a bad start in the title match, he has won two games in a row and now needs just one more win to  take the title.

Ko Iso leads Meijin League: Two games were played in the 40th Meijin League last week. On April 6, Ko Iso 8P (B) beat Murakawa Daisuke by 3.5 points. On April 9, So Yokoku 9P (B) Cho U 9P by half a point. There are four players with only one loss in the league, but Ko holds the provisional lead by virtue of having completed five rounds. His score is 4-1; the other players are Rin Kono 9P on 3-1 and Yamashita 2015.04.13_Kono-RinKeigo 9P and Takao Shinji 9P, both on 2-1.

Quadruple ko: A game between Kono Rin 9P (left) and Mitani Tetsuya 7P (black) played in the main section of the Gosei tournament on April 6 was declared no-contest (by agreement between the players) because of a quadruple ko. There were two double kos in Black’s position, one in the top right, the other in the bottom left. So long as these kos continued, the game could not end, but it was so close that Black could not afford to add a stone inside his territory to finish off either ko.
        This was the 24th no-contest in an official tournament at the Nihon Ki-in. Eleven of them were from quadruple kos, ten from triple kos, and one from a quintuple ko. The other two were from “chosei” or “eternal (or long) life” (an example is given on page 185 of The Go Players Almanac). Chosei is a hypothetical position that first occurred in a professional game in 1993 and then again in 2009. According to Wikipedia, it also appeared in a Korean game in 2013. Incidentally,  a chosei is embedded in the floor of the concourse of Ichigaya Station (the closest station to the Nihon Ki-in), just before the ticket gates.

LG Challengers Cup: To commemorate the 20th anniversary of the LG Cup, an international tournament for players 18 and under was held at the Korean Kiwon (Ki-in) in Seoul on April 10 and 11. At stake was a seat in the main LG tournament, which starts on June 8. There were eight players from Korea, including inseis, and four each from Japan and China. Representing Japan were Ichiriki Ryo 7P, Kyo Kagen 3P, Fujisawa Rina 2P, and Mutsuura Yuta 1P. Three of these players were eliminated in the first round, but Kyo Kagen made it to the second day; he lost to the eventual winner of the tournament, Byan Sang-il 3P of Korea, in the semifinals.

Seattle Report: Playing Go Is Like Making Kimchi

Saturday April 11, 2015

Sakura Con 2015 overall shotThe Seattle Go Center had their own room at Sakura-Con, Seattle’s big festival of Japanese anime, manga and games, which was held last weekend, April 3-5, in the Washington State Convention Center.  One volunteer, John Richards, put in 32 hours of teaching, and several volunteers provided more than 20 hours of instruction.  At peak times, more than 10 volunteers were teaching at once.  The students ranged from complete beginners to single digit kyu players who come by each year to get more instruction.

I enjoyed the observation that Solomon Choe 6d made while playing one of the students on a 19×19: “You know, playing go is like making kimchi.  That group is kind of dead. [And I don't want to add more stones to it right now.] But I want to preserve it. I want to put it in a pot underground and see if something magical happens.”  Report/photo by Brian Allen
