For those who are interested on more in-depth analysis on the topic.
https://en.chessbase.com/post/alpha-zero-comparing-orang-utans-and-applesTLDR: It turns out that there are some shades in this stunning 28:0 (=72) result. Stockfish played on small and iappropriate hardware, with its databases for openings and endgames switched off. Moreover , the used time control( 1 minute per move) make no sense , either for humans and computers, and cause huge problems for Stockfish's way of finding proper moves. I would also like to know why only 10 games were released. Sure, they are beatiful ( I have seen all of them already on YT), but considering the fact AlphaZero played against crippled version of Stockfish , having its opponent playing in way lower strength that it is supposed to be... well, you can play nice games agaist way weaker opponents anytime ;)
In overall, this looks like Google marketing way more than anything else. There was no proper match - Google experts just set up opposing program in the way it had to lose, inevitably.
