My prompt is: "Let's play chess. Show me the board each time." Which gives something like:

      a b c d e f g h
  8 | r n b q k b n r | 8
  7 | p p p p . . p p | 7
  6 | . . . . . . . . | 6
  5 | . . . . . . . . | 5
  4 | . . . . P p . . | 4
  3 | . . . . . . . . | 3
  2 | P P P P . . P P | 2
  1 | R N B Q K B N R | 1
      a b c d e f g h

I suppose I could use an external representation and paste that in, but I could also have it write a python script to use stockfish.
