There's a lot of chess configs, but there's a LOT of atoms in the observable universe. I suspect there's a few in the unobservable universe too.
Chess configs = 4.8 x 10^44, Atoms > 10^70

You might be able to pull off a low-resolution lookup table. Take some big but manageable number N (e.g 10^10) and calculate the maximally even distribution of those points over the total space of chessboard configurations. Then make a lookup table for those configs. In play, for configs not in the table, interpolate between nearest points in the table.
I didn't say chess positions, I said chess games. That number has a lower-bound of 10^120.
