Seems this might still have the problem of moves being either extremely good or extremely bad depending on how many good moves are found, rather than playing at a consistent level. Or for example in a degenerate case where there are only two moves and one leads to mate, the computer will be picking randomly.
I don't know enough about chess but surely amateurs don't play at a consistent level. Like, I play a little and I'm quite certain some of my moves are awful (20%?) and some are the same move magnus makes (10%?) and most are on a spectrum between (70%?).
