Would it be feasible to create a complete lookup table of 'best' moves for all given board configurations? I'm not sure how to determine the total number of configurations. Not the same as a tablebase, just a single next move rather than sequence to checkmate.

It wouldn't be competitive against top tier players and AI, but I wouldn't be surprised if it could beat me. 'Instantly' knowing the next move would be a cool trick.

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-...
