The amount of data that would be required for a lookup table for all best moves for every board configuration would be infeasible.
They have managed to create one for 7 pieces. Last update on trying to get to 8 piece database: https://www.chess.com/blog/Rocky64/eight-piece-tablebases-a-...
Yup, and it looks like a complete tablebase from the start of the game won't ever be feasible.
> From May to August 2018 Bojun Guo generated 7-piece tables. The 7-piece tablebase contains 423,836,835,667,331 unique legal positions in about 18 Terabytes.
Almost halfway there ;)
