Oh, did they change the pairings? Mr Kin's tournament table says it would be Ke vs Gu. http://igokisen.web.fc2.com/wr/cl.html. Btw Ke vs Mi was another example of the "wrong" close approach to Kobayashi that's popular these days.

I'm not sure, but I think I remember that sometimes when there is a draw that happens later, Mr Kin will print a table, and then shuffle it when the later rounds are revealed. It's one of the limitations of presenting a tournament table.

That is correct. Mr Kin builds those tables from the beginning of the tournaments. They often have to be adjusted at later time.

Good to see Park doing so well. He's one of my favorite players. I really enjoy his calm and balanced style.

Indeed, a characteristic game for Park when he is in good shape. Not sure what was Ke Jie mistake in fuseki, but thereafter Park play looked so smooth and effortless.

I am happy to see the nimble Tan Xiao in his first world final. I checked on go4go but couldn't find a head to head Park - Tan, did they ever play together?

I too like Park Yeonghun's calm territorial style, though I found it interesting that in his game with Ke Jie he did that fancy attach on the top right corner to make shape in sente and swallow up the invader, whereas Lian Xiao just did the simple attach on top of the invader (and all those stones subsequently died).

This is a great chance for Park to win his first international title in almost a decade: he won the Fujitsu aged 19 in 2004 and again in 2007. He had a bit of a resurgence last year (https://www.goratings.org/players/125.html) but lost in the final of the LG cup to Kang Dongyun (beat Park Junghwan and Tuo Jiaxi on the way).

According to Nie Wei Ping in this video
https://www.youtube.com/watch?v=Ys3Rl9bhXrM

white had a good start after the first exchange at the top right (after W Q12, white right side has almost no aji whereas black influence at the top still needs to be demonstrated).

Then after the second exchange in the left bottom and white got sente to play the G16 move, annihilating black's top influence, the game was almost lost for Ke Jie.

In the post match interview,

Ke Jie said that he still doesn't know what is the good play for black after the first exchange at the top right since he too thinks that white is better.

Thanks for the comments about the top right: that attachment does seem to be played a lot these days in a variety of positions and gets some nice results. But I can't help but wonder if the blame can be traced back to the solid connect at the lower right (move 11). I know this is a very common move, and the idea is to not give white the sente turn (though not 100% as we see in related AlphaGo opening) to bolster the right side so leaving more severe invasion aji, but it just looks so inefficient to me with the original shimari stone. I had a look at ps.waltheri and it has a bad win percentage whilst push on top is good, so I think my feelings may be be onto something here. I can't imagine AlphaGo would play the connection, and in the related AlphaGo opening with a 3-4 high approach attach under joseki in progress at top right it famously prefers to push on top instead of descend to 2nd line.

Hi, could you tell me what website or application your screen capture is from? Thank you!

For those of you who speak Chinese, here is an analysis of the game between Ke Jie and Park Yeong-hun by Chang Hao (9p).
If anyone who has watched this could give us a summary, it'd be much appreciated. I myself am specifically interested in what Chang Hao thinks is the losing move(s) or losing exchange(s) for Ke Jie.
