	https://www.chess.com/news/view/new-alphazero-paper-explores-chess-variants Kramnik had the privilege of getting access to at least 44 million games played by alphazero. 44 million games was the number given by deepmind to train 9 hours Alphazero but it most likely didn't stop with those 9 hours. The alphazero database has never been released for the public probably because it would be commercially not interesting to do. So the question is rather: Is it ok to use statics in a course which nobody can verify? I am inclined to say rather no. From a teacher I expect transparency and trust. I miss that here.

	Two sources I am aware of are CCRL and TCEC: https://ccrl.chessdom.com/ccrl/4040/games.html https://github.com/TCEC-Chess/tcecgames

	Maybe these were dynamic games played as a Monte-Carlo (probabilitic) evaluation of the position: the computer generates N random games and checks the final score to see what's going on. In this case, the dynamic games are lost.

	In a recent Chessable video course, Kramnik made repeated references to how many engine games there were from a particular position, and what the statistics were in such games. For example, in one mainline position, he would say something like "There have been over 200,000 engine games from this position, and the statistics have been very good for Black." Does anyone know what database he might be referring to? TWIC doesn't include these games, does it? Is there a similar site for regularly downloading engine games?
