“The Chess Life article (Your Move/Readers Write: ‘Catching Chess Cheaters’ 6/23 EJ) says that ‘One interesting statistic is that players make 60 percent to 90 percent more errors when half a pawn ahead or behind compared to when the game is even,’” writes Michael Redmond 9P.
“How would you compare half a pawn in chess to a point advantage in go? I don’t know how big an advantage that is for chess masters, but I think that Regan’s observation that the players’ assessment of a game position — and the assumed emotional value — is affecting their ability to think is also true of go players, but to a lesser extent, depending on how big a half pawn is.”
“The article seems to imply that while the player at a disadvantage might have reason to play a high-risk/high-reward move, the winning player must try to play the correct move always. He uses this reasoning to conclude that the players are actually making errors. I suppose that chess, being a race to kill, does not allow for calculated mistakes, but this seems to be less true of go, and could indicate a difference in the endgame stage of the two games.”
“In go, there can be calculated ‘errors’ by the player with an advantage. As a go game nears its end, the leading player can often calculate a win without playing the optimum moves. My opinion is that top go players will sometimes choose technically incorrect moves when 2.5 points ahead, a calculated choice to simplify the game. Such calculated ’mistakes’ by the winning player are usually minor, and two to three mistakes can add up to a one point loss in actual play when compared to the correct endgame sequence. Anything more than that is probably a ‘real’ mistake.”

“I read about the Go Camp in Japan (Nihon Kiin Organizing Special Go Camp to Celebrate 90th Birthday 3/22 EJ) this summer,” writes Bob Barber. “I will be in Japan for a wedding, so I couldn’t actually join the Camp, but if I can fit it into my schedule, it would be interesting to hang on the sidelines and at least see some of my buddies whom I no longer see at Congress.” Anyone planning to attend can reach Barber at email@example.com. The EJ is also interested in reports from the Camp; email firstname.lastname@example.org

With the start of the 35th World Amateur Go Championship now less than two weeks away, it is time to take a look at the field. Fifty-seven players from a like number of countries and territories are scheduled to make the trip to Gyeongiu, Korea to compete in the four-day, eight-round Swiss system. Many will be veterans of previous tournaments held in Japan and China, some drawn back to WAGC competition after a long absence, perhaps by the chance to be part of the first WAGC held in Korea. As usual, the largest contingent will come from Europe (30 players) and the youngest from the Far East (15 players, including an 11-year-old from Indonesia).
China, whose players have won this championship seven times so far during the current century, will be represented by Wang Ruorang, a 16-year-old from Nanjing who took third place in the Chinese Evening News Cup in January. Normally the winner of the Evening News Cup represents China at the WAGC, but the winner also has the option of turning pro any time during the ensuing year, and this year’s winner, 13-year-old Yi Lingtao, took that option immediately. In the meantime, Mr Wang has been doing famously, beating a pro opponent right after the Evening News Cup, beating last year’s WAGC runner-up in March, and leading an eight-man Chinese amateur team to victory over a Korean team in April. One recalls that Qiao Zhijian, the Chinese player who won the WAGC two years ago (and then turned pro) was also 16.
Korea, which has won the WAGC four times this century, will be represented by Tae-woong Wi. Mr Wi (age 20) qualified by winning the Korean amateur Guksu title last December, beating the 2010 world amateur champion in the final match. That feat, added to second-place finishes in the Lee Changho Cup and the Nosacho Cup and a 9-3 performance in National League competition, boosted him to second place in the U40 division of the Korean amateur rating system. The Wang-Wi game should be a highlight of the tournament.
Japan, which won the WAGC in 2000 and 2004, will send in Kiko Emura, who represented Japan at the WAGC and the Korea Prime Minister Cup in 2013. Last February Mr Emura also represented all human go players when he trounced Zen, Japan’s and perhaps the world’s strongest go-playing computer program, in consecutive games on 13 x 13 boards.
Other players to watch include Naisan Chan (Hong Kong), who took 3rd place in the 2009 WAGC; Yongfei Ge (Canada), who defeated a professional opponent at the SportAccord World Mind Games in Beijing last December; 16-year-old Yi-Tien Chan, youngest of the 22 amateur 7-dans in Chinese Taipei; Sang-Dae Hahn (Australia) and Liang Jie (USA), who also have 7-dan ranks; Czech champion Lukas Podpera; Dutch champion Merlijn Kuin; Finnish champion Juuso Nyyssönen; Hungarian champion Pál Balogh; and Serbian champion Nikola Mitic. Competition for the top ten places should be fierce.
For those who miss out, there will also be two prizes awarded for fair play and fighting spirit. And for everyone there will be a warm week of Korean hospitality. A particular attraction will be the Gyeongju Baduk Festival, July 5, 10:00-12:30 at the tournament hotel (the Hyundai Hotel), where local players will play friendship games with the contestants, Korean pros Lee Hyunwook and Bae Yunjin will play simultaneous games, and former pro world champion Cho Hunhyun will give autographs.

Israeli go champion Ali Jabarin 6d (right) has won the final knockout rounds of the European Pro Qualification Tournament at Vienna in Austria to become the second pro qualifying under the new European Go Federation (EGF) /CEGO pro system (see Pavol Lisy First European Pro – EJ, 6/1). He beat Mateusz Surma 6d of Poland then Lukáš Podpera 6d of Czechia in the two closely-fought knockout rounds comprising this third and final stage of the competition to select two pros from sixteen of Europe’s strongest amateur players. Israel, though not geographically part of Europe, is usually treated as European in international sporting contests and is an EGF member-state. The games were played at the Freie Waldorfschule Wien West on Friday June 20 as a preliminary to the Vienna International Go Tournament, which Jabarin also won, in a field of almost 100. The pro qualification tournament was overseen by Wang Runan, the President of the Chinese Weiqi Association.
The two new pros, Pavol Lisy and Ali Jabarin, will receive their certificates – at which point they officially gain professional status – at the upcoming 58th MLily-WeiqiTV European Go Congress in Sibiu, Romania next month (July 26 – August 9), where they will still be entitled to compete as amateurs. After that they will go to Beijing for another six months’ intensive training. Next year will see the first Bonus Point and Grand Slam Tournaments as well as another Pro Qualification Tournament to select a further two pros. These special tournaments are all part of a complete professional system which is detailed in the EGF/CEGO Agreement (pdf, 6.85Mb).

“Chess Life recently published a fascinating article, ‘Catching Chess Cheaters’ centered on using computers and statistics to detect cheating in chess,” writes John Pinkerton. “It covers many related topics of interest to go players such as rating inflation, comparing players of different generations, the statistics of move quality, and computational complexity theory. One interesting statistic is that players make 60 percent to 90 percent more errors when half a pawn ahead or behind compared to when the game is even. It’s believed to be a cognitive effect, not the result of high-risk/high-reward play, because it’s seen in both the player ahead and the player behind.” Graphic courtesy Chess Life; cover photography by Luke Copping
