Life In 19x19

Ke Jie beat Fu Chong 6p in 78 moves. Round of 16 of some event, mostly Chinese players but also Choi Cheolhan so maybe Chinese league finals or just some event Koreans did really badly in? He lost to Tang Weixing in round of 8 though.

This is the Chinese Southwest Qiwang tournament. Choi Cheolhan is a guest player because he has been representing a league A team in that region for many years.

Chinese Southwest Qiwang (中国围棋西南棋王赛) is a regional tournament for Chinese players from southwest China (covering three provinces Yunnan, Guizhou and Sichuang & the municipality Chongqing). In practice, players born in that region, or those representing league teams in that region, or indeed anyone the sponsor considered fit, are invited to play.

Here's the game, quite a few AlphaGo-esque moves from Ke Jie:
- 6 as ye olde players would have told us, approaching 3-4 is bigger than answer approach to 4-4.
- 16 (instead of e17 connect)
- 30 and 36 attaches AG likes.
- 44 don't be afraid of them double approaching your 4-4, particularly as k3 makes lower side boring.
- 58 tesuji not invented by AG, but this kind of bad aji is one reason it probably doesn't like the b4 slide.

Ke Jie had some tough time in recent months. Across seasons he lost 6 games in a row in the Chinese A league. Today he fought really hard to beat Gu Zihao to break that losing streak - very exciting game.

Ke's slump continues, lost to Japanese wonderkid Shibano Toramaru 7p in the China vs Japan Ryusei match. Might even lose his #2 spot on goratings soon.

Some good news for Ke Jie at last: he just beat Park Junghwan in the 5th round of the Chinese league, and as black as well! (white won 14 of their 15 games to date)

Ke Jie won both of his games in the Quzhou-Lanke cup against Li Qincheng and Jiang Weijie, respectively. His next opponent is against the young Liao Yuanhe 6P, who I believe is 0-3 against Ke Jie.

Ke also just won his game against Shi Yue in the 6th round of the A-Leagues as well and cut into Park Junghwan's lead slightly. The last time they were this "close" was around February I believe. Hopefully, this is a sign that Ke Jie is regaining his form.

Ke Jie now has a 2-game losing streak again after losing in the first round of Mingren against Tong Mengcheng and then the 7th round of A-League against Lee Sedol. However, Park Junghwan has lost 2 in a row as well after Chen Yaoye beat him in A-League.

Lian Xiao continues his great form and has now reached his highest rating ever.

Ke Jie beat Shi Yue today in the final match of the knockout tournament to determine the four finalists of the Longxing.

In the game, Ke Jie invaded the 3-3 on the 3rd move!

Another disappointing and upset loss for Ke Jie today, this time against Won Seongjin. Ke Jie resigned after not being able to continue a big ko.

It seems likely that Ke will slip into #3 on goratings now.

I've seen a detailed AI analysis. Ke played really well in the first half of the game, gradually building a comfortable lead. Then he made a big mistake at B127. Interestingly the report shows that Ke Jie is by far the most AI-like player among those participating the LG cup. At opening stage, 79% of his moves match what the AI would play (the 2nd best has only 68%).

Ke Jie and Lian Xiao will finally get to play each other, as both advanced to the final of Longxin Cup (best-of-3).

Ke Jie defeated Lian Xiao in the first game of the final, and he retains his no.2 spot for another day. The second game will be played in about one and a half(?) hours.

Second game, Lian Xiao (White) won by resign.
Third game tomorrow...

Ke Jie (w) won the deciding game by resign.
