Are you being deliberately obtuse, Herman? I have "seen and heard" MOST of the candidates both now and when I wrote that last post. Yes, you're right in the sense that, if I haven't heard a particular pianist, there's no understanding involved. I was speaking of the ones which I HAD heard. Make sense?
Speaking of which, last night, Ms. CfL and I watched the second round performances of a few of the pianists we hadn't seen previously (and who, we now know, have made it into the third round):
Nikolay Khozyainov (Russia) - Excellent articulation, but he had a preference for slow tempos which occasionally added a bit of heaviness to his interpretations IMHO.
Su Yeon Kim (South Korea) - Excellent player, for both imagination and technical control. I really liked her playing. Ms. CfL didn't like her often anguished facial expressions! (But what does that have to do with her playing, I asked!) I mean, I really liked her high heels myself - but what does that have to do with her playing? ;-)
Aimi Kobayashi (Japan) - Although she sometimes seemed to lack sheer power (as in the initial outburst in the Second Ballade), she's an absolute master of pianissimo to piano dynamics - what a variety of nuances she gets within such a restricted dynamic range. In this sense, she's a rival to Pavel Kolesnikov, who already seems to have a great career going. Definitely impressive.
Mateusz Krzyzowski (Poland) - We weren't that impressed, and we agree with Andy that he's a beneficiary of the six Polish judges on the jury!
I also want to say something in general about most of the performances we've heard so far: most of these competitors are oh-so-aware of every little change in harmony or texture (or whatever), and they seem to have been coached to make a point of showing that they're aware by taking some combination of rubato and dynamic changes (and, often, facial expressions and body language too!) at every opportunity. It's all a bit much as far as I'm concerned. And I think that, in general, the Chinese were the worst with this habit. Ms. CfL and I were talking about the possibility that these Chinese pianists are all modeling themselves after Lang Lang - after all, he's the most successful Chinese classical pianist in history (even more than Yuja). They see him on TV or YouTube and they think that that's the way they ought to play.
I think back to something which Ms. CfL's father said to me: "So many pianists today play as if there's an exclamation mark at the end of every phrase!". LOL!
