Body: <p>The Nalimov/Syzygy, etc tablebases are, as far as I know, computer databases that store all the possible possitions in the board, with the best moves and the outcome of the game, assumming both players work perfectly.</p>
  <p>Is there still work on them? I think all the positions of 7 or less pieces are solved by now, but I don't know if there are computers out there at the moment, calculating positions and adding them to these databases.</p>

  Certainly there is work on 8-man tablebases.
  
  One source of information on this is from the Chess Endgame Study Association [here](https://arves.org/arves/index.php/en/latestnews/latest-news/2-ongecategoriseerd/1509-8-men-tablebase-first-explorations) This article describes pawnless ending work.
  
  It is simpler to start with pawnless endings as there are fewer possible positions to evaluate. And evaluating all endings with pawns depends on evaluating the pawnless ending that occur after promotion.
