This is a fantastic project. Thanks for sharing!

I had a nice long conversation with two of the authors of [0] at ACL.

One thing we discussed was the reverse problem. That is, as a player, could I give commands to the model and have the engine figure the moves that would best satisfy them.

This ranges from concrete like "take the black square bishop" (there is still variability like which piece should take it or if it's even possible) to more complex positional stuff like "set up to attack the kingside."

Any thoughts on this line of research?
