The 9th Round was played on July 30th, 2019 in Lulang/Linzhi, Tibet. Again Yike smart go board was used.
Here are the game results:
Team Jiangsu 0:3 Team
ShanghaiB1:Yu Zhiying 6p vs
Rui Naiwei 9p (W+0.5)
B2:Wang Chenxing 5p vs
Tang Yi 3p (B+R)
B3:Yin Qu 2p vs
Pan Yang 3p (W+R)
Jiangsu meeting Shanghai is a clash of titans in many levels. They are the league leaders for the past a few weeks. Jiangsu is the only champion the WAL ever had and Shanghai has always been a strong contender. Rui Naiwei sensei was the former female number one not just in China but also in world. Yu Zhiying is the current number one in China. It is no surprise that CCTV (China Central TV) chose Rui vs Yu as the live broadcast game for this round.
And the result is not just surprising but even a bit shocking in my opinion. The six time champion Jiangsu got swept by Shanghai the perennial contender.
The focus of the round is on Rui vs Yu. Before the game Rui sensei actually felt dizziness and was planning on breathing some oxygen during the game. But once it started she was too immersed in the game to do so. Yu Zhiying had a comfortable lead into the late endgame and it seemed her victory was inevitable (FineArt win rate was approaching 100%). But somehow she missed an aji in her territory and Rui sensei did not miss that opportunity. White's move 156 was the attachment needed to exploit the weakness and capture two black stones. Yu Zhiying simply could not recover from a blunder this late into the game and lost by precisely half point.
Undefeated Wang Chenxing 5p was taken advantage of in an old style joseki in lower left corner. National team coach Yu Bin 9p smiled at the shape and said it had happened to him too long time ago. Kobayashi Koichi used to play that joseki. Tang Yi 3p was able to hold on to the lead. Yin Qu 2p's dragon was slayed by Pan Yan 3p which also ended the game.
Shanghai gained two points and takes the sole lead in the league.

The Rui vs Yu game was not the only one that featured a big blunder in the endgame. It happened in the Lu Minquan vs Ding Mingjun game too, and this one is probably more costly.
Ding Mingjun played a really strong game and used a big ko fight to gain a decisive advantage. Going into the late endgame Ding had an insurmountable lead of about 15 points on the board. The only reason Lu Minquan was still playing was probably because 1. this is a team event; 2. there was still a ko left. But Ding did not need to win the ko and would still won by a bunch. But somehow she did not respond to White's ko threat and made her own ko threat instead with move 291. The resulting trade was not even close and Ding lost the game by 2.5 points.
To make things even worse, this was the game that finished last in the whole venue and her teammates had one win one loss. Had she won, Team Hebei would have won their first match of the season.
Ding Mingjun in tears after the loss. This is probably the time you realize she is only 14 years old.
Team
Hangzhou 3:0 Team Shanxi
B1:
Fang Ruoxi 2p vs Wang Zixin 1p (B+R)
B2:
Gao Xing 4p vs Gu Wanshan 1p (W+R)
B3:
Wu Yiming 1p vs Chu Ke'er 2p (B+8.5)
Yu Bin 9p's nickname for Wu Yiming 1p is "Little devil(小魔女)". This is also her Chinese handle on Fox Go Server (her English username is Snowbaby). She replaced Song Ronghui 5p to play against her fellow class 2018 new pro Chu Ke'er 2p. In the opening she sacrificed upper left corner to build a mojo on the right, which gained praise from Yu Bin 9p. Yike's AI initially lowered black's win rate. But after white's invading stone got cut off black's win rate shot up. Chu Ke'er was able to get the invading group to safety but black's mojo also turned into territory. In the end the players did not intend to count but the enthusiastic referee took a picture of the board and Yike's APP automatically counted. So the result was recorded as B+8.5 instead of B+R.
Gao Xing 4p and Gu Wanshan 2p also won their games and Hangzhou swept Shanxi 3:0.

B2:Zhang Zihan 3p vs

Reigning Female Mingren Chen Yiming 4p won an easy game against Zhang Zihan 3p but her teammates could not get the second win.
Team Shaanxi 0:3 Team

Cho Hyeyeon 9p (W+2.5)
B2:Li Xinyi 2p vs
Zhou Hongyu 5p (B+R)
B3:Luo Chuyue 3p vs
Li Xiaoxi 3p (W+R)
It was somewhat surprising that this was actually the first time Korea's Cho Hyeyeon 9p played against Li He 5p given both players were active in international events. The game was close to the end but Cho 9p found a nice endgame tesuji to win by 2.5 points.
Li Xiaoxi 3p again requested an oxygen tank and beat Luo Chuyue 3p. Maybe she should consider bring an oxygen tank with her to games from now on

Jiangsu slipped to 3rd place after the sweep by Shanghai. Hangzhou moved to 6th place and further away from demotion. Poor Hebei is still winless.
