Life In 19x19

The National Individual Championship started in 1957 and used to be the most important domestic tournament in China. The biggest names in Chinese Weiqi scene like Chen Zude, Nie Weiping, Ma Xiaochun etc. all have won this tournament multiple times during their heydays. The winner of the tournament was deemed best player of the time during early editions. It wasn't until late 90's the importance of the tournament diminished due to emergence of many tournaments with much higher prize money and the A-League. Nowadays this tournament is considered battle ground for young pros and test bed for new pros. Top pros like Ke Jie, Mi Yuting, Lian Xiao do not participated in it (although Mi Yuting did win it in 2012 when he was 16 years old, 1 year before winning the M'Lily Cup). But most top female pros still play in this tournament, sometimes in the men's group. This year Yu Zhiying and Rui Naiwei did just that.

I am covering it this year because several new pros are playing and I want to see how they fare against more seasoned pros. I also want to see how many games can Yu and Rui win in men's group.

There are 120 players in Men's group and 58 players in Women's group. Tournament is scheduled so that Men's Group will play 13 rounds while Women's Group will play 9 rounds, but both groups will start and finish on the same day (from Sep 17th to Sep 30th). Because Women's group has more time they play with 2 hours main time while men's group play with 1 hour main time. On certain days Men's group need to play two games in one day.

Edit: The first National Individual Championship (NIC) was held in 1957 not 1954. By the way 2019 is the 53rd edition. There were a few interruptions during the Cultural Revolution.

Here are results for the names I am tracking:

Rui Naiwei 9p won while Yu Zhiying lost. 2019 PQT 1st place winner Wang Chunhui 1p had won two in a row, but he ran into Fan Yunruo 8p in round 3 and lost. Fan 8p is the player with highest CWA rating in the field. He is 11th in the latest ranking. Wang 1p will play Rui 9p next.

Women's Group Round 2

Amateur color coded cyan (The National Individual used to be open to amateurs. Now the Men's Group does not allow amateurs anymore but the Women's group still carries this tradition and allows WBL teams send 1 to 2 amateurs to the National Individual provided that they do not have enough pros)

Edit: Wang Siyin should be 2p.

Women's Round 3

I will start to track Yan Ximo 5D from now on. She won two in a row so played Wang Shuang 4p at board 1! This will be valuable experience for her to be playing at board 1 in the NIC even though she lost.

Zhou Hongyu 5p lost to Lu Minquan 5p in round 2 so she played (and beat) Li Xiaoxi 1p in round 3.

After 3 round 8 players are undefeated, including Li He 5p, Wang Chenxing 5p and Chen Yiming 4p. Wu Yiming got her first win.

PQT medalist Wang Chunhui 1p lost to Yan Huan 6p but beat Ying Yitao 4p to go 4-2 in first 6 rounds which is quite impressive for a new pro. Another new pro Zhao Fei 1p did well by beating former A-League player Qin Yuexin 5p. Also 2018 new pro Wang Shuo 00 1p met his namesake Wang Shuo 90 5p in round 5 at board 17. The youngster was able to outlast his elder and improved to 4-1 after 5 rounds.

At the top highest ranked player Fan Yunruo 8p lost to Chen Xian 7p in the 5th round. After 6 rounds only Cai Jing 6p and Chen Xian 7p remain undefeated. They play each other in round 7.

Cai Jing 6p (right) lost to Shen Peiran 5p in round 8Taiwan vs Taiwan: Chen Zhengxun 5p (left) beat Pan Tingyu 3p in round 8. Both are affiliated with the CWA (I think that means they cannot participate in Taiwan Qiyuan events)

Women's Round 6

Amateur Yan Ximo 5D beat Wang Xiangyun 3p and improved to 3-3. Wang Xiangyun 3p won the NIC women's group championship back in 2005, and she did it as an amateur! After the NIC the CWA decided to give her a special promotion to pro shodan. She might be the only younger generation female pro that did not go through the PQT to earn pro status.

Wu Yiming lost to Wang Siyin 2p. She has two wins after 6 rounds.

Li Sixuan and Li Xuemeng have the best records among new pros with 3 wins.

Yu Zhiying 6p and Rui Naiwei 9p both won in round 10. They stand at 5-5 and 4-6 respectively.

Wang Chunhui 1p beat Chen Yafeng 2p to go 6-4 and is the best among new pros. As a 13 year old he definitely deserves a close look by some A-League teams. Zhao Fei and Hua Chang tied with 5 wins each.

At the top of the group Chen Xian 7p beat young star 2018 new pro Huang Chunqi 3p and continue to lead with 9 wins. The other leader Wang Zejin 6p lost to Liu Yuhang 5p and slipped to the 8 win group, which included Fan Yunruo 8p, Wang Xinghao 4p and several more.

Women's Group Round 7

The surprise of the round is certainly 13 year old new pro Li Sixuan 1p beating 2019 Jianqiao Cup finalist Pan Yang 3p. Together with Li Xuemeng they lead the new pros with 4 wins.

In a battle of two PQT medalists 2018 winner Wu Yiming 1p beat 2019 winner Zhang Mengyao 1p. Next round Wu Yiming (who is still couple months away from her 13th birthday) will play a younger player for a change, and that is amateur Yan Ximo 5D.

Li He 5p beat Zhou Hongyu 5p to stay undefeated. Chen Yiming 4p, Wang Chenxing 5p and Wang Yubo 3p trailed with 6 wins.
