This was the third iteration of this invitational match and Choi Cheolhan won by 1.5 points.

The first of these matches was played in 2012 and the players were Ma Xiaochun 9p and Liu Xiaoguang 9p. Ma won the game.

In 2013, Lee Sedol 9p and Gu Li 9p were invited to play in Jingdezhen, and Lee emerged victorious.

An interesting opening

Chen held black and the opening of the game was interesting.

Chen Yaoye 9 dan.

Chen started the game with a variant of the Micro Chinese opening, and established some territory at the top.

Choi responded by attacking Black’s left side group, with alternating jumps in the center and at the bottom, up to 40.

Black dies, but maintains balance

The middle game started with move 41. Black built a large territory at the top up to 73, while White continued attacking Black’s left side group.

After White cut at 78, Black’s left side group was captured. However, Black 93, 99 and 101 were a good combination, and the game was still well balanced up to 109.

Black started a leaning attack against White’s center group with 111 and 113, but the result up to 134 wasn’t particularly successful, so the game was still even.

Both players falter

White 142 was a mistake, and Black punished White with the powerful combination of 149 and 151. As a result, Black captured some of White’s stones and took the lead.

Black 169 was a mistake, and Choi didn’t miss his chance.

White 170 and 172 were good endgame tesuji, and the game became very close.

Black 181 was another questionable move and the game was reversed when White played at 182.

After that, both players’ endgame was perfect, and Chen didn’t get any more chances to reverse the game.

Choi Cheolhan conquers his demons

Before this game. Choi’s head to head record against Chen was 4-10 in Chen’s favor. We’ve talked about how Chen seems to be Choi’s Go nemesis on several occasions.

In particular, Chen defeated Choi in eight consecutive games, from 2007 to 2012.

However, Choi defeated Chen once again in Jingdezhen and their head to head record since 2013 is actually 3-1 in Choi’s favor now.

About the Jingdezhen matches

Last year, this exhibition match was called the Tianxin Pharmaceutical Cup, but it’s also sponsored by the city of Jingdezhen itself.

At the 2013 match between Gu Li and Lee Sedol, there was also a meeting to finalize details about the MLily Gu vs Lee Jubango.

After that meeting, the jubango was realized.

The winner’s prize is 150,000 RMB (approx $24,500 USD at the time of writing) and the runner up receives 100,000 RMB (approx $16,000 USD).

The time limit for the game was 2 hours and 30 minutes with 5 x 60 seconds byo-yomi for each player.

The game was played under the Chinese rules, with komi of 7.5 points.

Jingdezhen City

Jingdezhen City (景德鎭) is located in Jiangxi province, China, and is very famous for its China (porcelain). It’s also the hometown of Chen Yaoye’s father.

The popular blue and white porcelain which originated in China is made in Jingdezhen – even the trophy for this match was made in that style. Ceramic Go stones are also made in Jingdezhen and an annual ceramics expo is held there.

Podpera Takes Top Prize at European Youth Go Championships

Lukas Podpera 6d (left) of the Czech Republic won the Under-20 division of the 19th European Youth Go Championship (EYGC) held in Bognor Regis, England Feb 28 – Mar 3, thereby securing himself a place in the GLOBIS Cup World Youth Go Championship to be held in Japan on 8 – 11 May 2014 (see Nihon Ki-in Announces New Under-20 World Tourney, EJ 11/30). Jonas Welticke 4d of Germany was runner-up and Frenchman Tanguy LeCalve 5d took third place. In the Under-16s, the top three places went to Alexandru-Petre Pitrop 2d of Romania and Russians Grigorij Fiorin 4d and Viacheslav Kaymin 3d, in that order, and the Under-12 category was won by the only dan player in his age group, Spaniard Oscar Vazquez 2d, with Denis Dobranis 2k of Romania runner-up. 89 took part in all. Click here for full results. Click here also for the results of the pair-go and doubles, held on the Sunday evening, March 2.

The events were organised on behalf of the British Go Association (BGA) by – mainly – Toby Manning, Tony Atkins and Sue Paterson,  and ran alongside the British Go Congress (see Double Victory for Cornel Burzo at British Go Congress, 3/3 EJ) at the Butlins Holiday Park, where competitors had full access to the many facilities and entertainments available for youngsters there. Japanese professionals Minematsu Masaki 6P and Kobayashi Chizu 5P (right) were in residence throughout, teaching and reviewing games. Kobayashi told the EJ she was impressed by the talent of the young Europeans, but stressed that to reach the highest levels it will be important for them to get good professional tuition, the earlier the better.

Bitcoin.io: A New Server With Unique Prizes

What do you get when you cross the world’s oldest game with the newest form of currency? A bitcoin go tournament, such as the ones being organized online every week at Bitcoingo.io. “Bitcoins are an ideal currency for an international game like go,” founder Steven Pine told the EJ.  “It allows students and teachers to connect and transact without concern for currency exchanges or waiting on a check or wire transfer to clear. The same is true for tournaments. I think the currency has lots of potential to transform the go community in many positive ways.”

Anyone can sign up, enter a tournament and begin playing on Bitcoin’s own Python/mySQL-based server. Komi is 6.5 points, and each player starts with 15 minutes; there are five 30-second overtime periods. Territory counting is used but no full rule set has been formally adopted. A tournament win earns the victor at least one point, depending on how many points their opponent has. A new tournaments starts, and the old one finishes, at midnight each Saturday. The self-paired “most points” format favors active competitors, so if you plan to play to win, you may need a comfy chair. The winner of the February 10 tournament had 78 points.

Bitcoins are notoriously unstable – last week it was discovered that as much as 5% of the total bitcoin money supply had been stolen from a prominent exchange without detection several years ago; the exchange declared bankruptcy. (NY Times 2/25/14) If you plan to convert your winnings to real-world money you may face a challenge. The weekly pot has been 6,000,000 “satoshis” but before you start planning your retirement, you should know that it breaks down to about $40 depending on the bitcoin’s daily value relative to the USD. (On 3/1/14 one bitcoin was valued at $556.85 on Coindesk, which monitors exchanges, down more than ten percent from just ten days before.) “Although the ‘satoshi’ – the smallest fraction of a bitcoin that can be transacted, currently .00000001th of a bit coin —  is not well-known, we decided to use it as a base unit to drive home the point that bitcoins are easily divisible and can facilitate micro payments,” Pine said. “Some services talk about ‘millibits,’ but we thought it would be more fun for people to win like 1,000,000 satoshis.” Pine and cofounder Jonathan Hales are underwriting the prizes themselves, hoping that tournament and teaching fees will make the site revenue positive.

If you check it out, bear in mind that it’s a work in progress.  Traffic is very low; a private room on an established server would probably bring in more users. But if you enjoy checking out new servers, Steven and Jonathan will appreciate your visit!

Go Game Guru Publishes MLily Gu vs Lee Jubango Game Commentary

Go Game Guru has just published an excellent detailed game commentary by Younggil An 8P on the second game of the MLily Gu vs Lee Jubango, which was played on February 23 on the outskirts of Shanghai. “Many people expected that Gu Li (right) would have something of an advantage in this match,” says An, “because most of the games will be played in China. However, it doesn’t seem like Lee Sedol is affected by that so far…Actually, it looks like Gu Li is under quite a bit of pressure from his fans and the Chinese media.”
