IMSA Elite Mind Games 2017

[Gomoto]

I like Park's play a lot. Achieving Ke's level of play with moves easy to understand. And not some crazy alien reading.

Interesting to review the games played at 30 sec per move.
The moves by Ke Jie are quite natural. No crazy alien reading here with the short time controls. (For example the game against Wang Yuanjun)

And perhaps no crazy reading due to the skill gap as well

Okay! But I do believe that the games you are referring to are actually still the 2 hour + 5 x 1 minute per move team tournament games .

In fact, the draw for all of the speed Go games should be here.

After the second round of the men's team event, Taiwan had the highest game score after shutting out Japan, and Korea and China had the same score down to SOS. If parings are decided by scores whenever possible, the fact that China happened to play Taiwan in round 3 meant it would have been difficult to win even if China beat Taiwan due to SOS meaning China still ends up playing Europe in the last round (this is speculation, however, as I am unsure as to the precise nature of the pairing system).

On another note for the women's side, if China won the last match against Japan, it would have come first. If China lost, it would have come third.

I'm currently looking at the rather interesting opening between Ke Jie and Ilya Shikshin...

I could only speculate that he was inviting black to fight as I have no way of knowing.

After what seemed to be an exchange of sorts on the lower side, white played into black's corner on the lower right! At one point I think one half of the board was full, with the other nearly empty.

Pardon my ignorance, but has a Western-born Western-federation-aligned professional ever played against the World #1 before? And for that matter, was this game with Ilya actually played whilst Ke Jie was #1?

There are some other games featuring Ke Jie, including one other against Ilya: https://www.goratings.org/en/players/1090.html

So Ke Jie beat Park twice in this event. However he took White in both games, and it seems like W always win in games between these two.

Interestingly, the AlphaGo tool has the first 24 moves of the 1st game between Park and Ke in its database. Aside from the first couple of moves up to move 6, the moves by Park that Master seems to disagree with most are , , and (?). Meanwhile, every one of Ke Jie's moves was Master's optimal move. Maybe Ke Jie has finally become AlphaGo!

Master thinks B should play a keima to the low approach on the bottom right at instead of the double kakari. It judges the keima on the bottom right 1.8% points higher than the game move. The next move that Master disagrees with is ; it thinks that Park should have made a 2-space extension instead of kosumi. I found this interesting because it seems straight forward that Master wants to reduce the effectiveness of the pressing move that AG loves in the following diagram.

Interestingly, Leela also agrees with Master about . W's stones seem to be working well after the exchange.
Finally, Master suggests at 'b', with the game move being at 'a'(AG has no variations for this move). After , Park's "winning percentage" stood at 39.2%, down from 44.9% at .

That game to move 20 is the same as the team go from the Wuzhen event. Park's kosumi is the move AG recommends, the attach the humans played at Wuzehn is -5% to 36% and then extend of move 26 minus a whopping 9.8% to 26%, it really was game over quickly! They did comment after how they changed their plan and the cut became a bad exchange if they were going to extend afterwards -- a case of too many cooks spoil the broth.
