Comments.Text: Try asking the Stockfish devs at Fishcooking https://groups.google.com/g/fishcooking. These datasets definitely exist, because they're used for training Stockfish's NNUE.

  (Asked by: username_0 on 2022-01-08)
  
  Is there anybody out there who knows about a very good dataset of chess **positions** (e.g. FEN notation or 64 fields with pieces in it) combined with a Stockfish-like evaluation score?
  
  I did find something on Kaggle, but the number of games was quite small so it wasn't good for Machine Learning purposes.
