Special correspondent Gu Ke reported On April 27, the third round of the second Quzhou Rotco Cup World Go Open, that is, the round of 16, was held at the DoubleTree by Hilton Hotel in Quzhou, with 8 Chinese mainland chess players playing, 3 wins and 5 losses, Gu Zihao 9 dan, Yang Dingxin 9 dan, Ding Hao 9 dan three advanced to the quarterfinals, Ke Jie 9 dan, Fan Tingyu 9 dan and other 5 people were eliminated. The quarterfinals will be held in Aksuwushi County, Xinjiang at the end of June.
In the first two rounds of the tournament on April 24 and 25, eight players from Chinese mainland advanced to the round of 16 and faced eight players from South Korea, Japan and Chinese Taipei. Last year's champion Koo Zi Ho 9 dan Zhi Bai faced Ueno Ai Misaki 5 Dan, who beat South Korea's Park Min-kyu 9 dan and China's Xie Erhao 9 dan in the first two rounds, causing a big upset.
But this game of chess Ueno Aisaki suffered a complete defeat, and the right set handover was a new type, and the two sides exchanged the field and external potential, but then Gu Zihao immediately worked easily in the black formation on the right handicap, and the winning rate rose to more than 90%. Turning to the upper left corner to fight, the black chess "three to one" was poisoned by white, and the situation fell to the bottom. The disadvantaged Ueno Aisaki forced a slow luck robbery in the lower left corner, but when looking for robbery materials, she found a "blind robbery" and had no choice but to admit defeat.
Yang Dingxin's nine-section white against his Chongqing teammates and South Korea's sledgehammer Yuan Shengqin nine-section, the upper left large-scale stereotype, both of them are familiar with the road, and more than 60 hands have not opened the gap. Then the battle on the right and below, Yuan Shengqin cleaned up all the changes, but it was also a move to eliminate his own robbery, and virtually eliminated the changes in the robbery of the remnants of the upper plate, and the winning rate of the two sides was opened, and Yang Dingxin began to lead.
When Yuan Shengqin robbed on the left side again, it was already a beat slower, because he couldn't find the robbery materials comparable to the value of the whole plate, Yuan Shengqin had to give in, and Yang Dingxin locked in the victory after eliminating the robbery. After that, Yuan Shengqin tenaciously insisted on more than 100 hands, but Yang Dingxin's leading situation did not waver, and he won the final game with 1 and 1/4 subs.
Ding Hao's nine-dan whitening against Chinese Taipei Lai Junfu eight-duan, who became famous in the first round of the last Rotten Ke Cup by upsetting and eliminating Ke Jie Jiuduan, but Ding Hao did not give him any opportunity to take advantage of this game and won a complete set. After gaining enough ground in the first half of the game, White took the lead in the middle of the belly to control the solitary on a large scale, unexpectedly blocking the way out of the black in the middle of the belly, and taking the lead by invading the upper right black formation.
Lai Junfu made a mistake in judgment during the battle, the door opened, and the white pieces infiltrated the black chess from the top right, sweeping away the empty potential that black chess relied on to win. Not only that, Ding Hao made inches, and also swept the black formation on the left side, winning simply and clearly.
Although Jiang Dongrun is a post-80s generation and Ke Jie is 8 years older, he blocked Ke Jie three times in the 2015 LG Cup quarterfinals, the 2016 Samsung Cup Top 32 Winners' Group, and the 2022 LG Cup Quarterfinals, forming a rare "inverted spring cold". In this game, Jiang Dongrun continued to write a miracle and once again stopped Ke Jie outside the quarterfinals of the Rotten Ke Cup.
In the lower right corner of the game, Ke Jie once again displayed his flexible style, discarding the discards in the right and upper right corners, and then making a big appearance on the lower board. Jiang Dongrun went deep into the lower left to form a robbery, and Ke Jie reversed the situation after the robbery.
Ke Jie, who was in the first hand, attacked the black solitary chess in the middle of the belly, but unfortunately there was a serious miscalculation, after Jiang Dongrun broke the white chess on the periphery, Ke Jie was forced to put the black chess live chess, and he could only save the upper left white corner by robbing. The two sides formed a big switch again, and after the black chess was eliminated, Ke Jie once again hated the Ke Cup.
Fan Tingyu 9 dan held the black against the Japanese lone Miao Iyama Yuta 9 duan, the latter was originally on the top of the lonely, but after a few moves, he jumped to the periphery, forming a thick momentum, and the winning rate rose to more than 90%. Later, Fan Tingyu once narrowed the gap in the winning rate, but in order to forcibly rob the left white chess, he ignored his own chess loophole, and was killed by Iyama Yuta on the left side of the game with a clever counterattack, and Iyama Yuta also became the only remaining Japanese chess player in the quarterfinals.
In the other three sets, Xie Ke 9 Duan failed to stick to the robbery due to lack of materials, and lost to Park Tinghuan 9 Duan by the smallest margin, and the latter also defeated Li Xuanhao 9 Duan by the smallest advantage in the last round; Zhang Tao 8 Duan and Jiang Qirun 9 Duan lost to Shen Zhenzhen 9 Duan and Bian Xiangyi 9 Duan respectively.
Quarterfinals: Gu Zihao 9th Duan VS Park Tinghuan 9th Duan, Ding Hao 9th Duan VS Jiang Dongyun 9th Duan, Yang Dingxin 9th Duan VS Shin Zhenzhen 9th Duan, Iyama Yuta 9th Duan VS Bian Xiangyi 9th Duan. The competition will be held at the end of June in Wushi County, Aksu Prefecture, Xinjiang.
