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?
