Is there any analysis of the Carlsen-Caruana World Championsip match by AlphaZero? How cool would it be to have the world's most powerful computer analyzing games played in a match between the world's two strongest human players? Has it happened yet and is the analysis available?
Yes, there is: AlphaZero on Carlsen-Caruana Games 1-8 and AlphaZero on Carlsen-Caruana Games 9-12. We don't have seen the PGNs with their concrete lines so far.

I'm not sure how helpful that is. Just one minute thinking time … seems to be a bit short. Some deeper calculation might be more valuable.
