We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time.
Ah, a butchering of a nice algorithm. :-P

This is not "as efficient as possible", but you already know that. :-)
It is also not as concise as it could be. Look at [this beauty](https://py.checkio.org/mission/the-longest-palindromic/publications/veky/python-3/although-straightforwardness-beats-speed/). :-)
And yes, comments are not really

OMG. filtering a lambda, then listing it, only to iterate through it. Hard to believe this wasn't intentionally ugly. :-P
How about
for b, w, n in states:
if n == n0:
(Indenting 2 spaces is acceptable in such situations, if you're stingy with line lengths.)
---
states[(b, w, n)]

LOL. Yes, sort might be unnecessary, but doing it twice... :-o And it even isn't one line. :-P

It's much better to use
if command.startswith('POP'):
since when you change POP to something else, you'll likely forget to change the 3.
Also, line 5:
if queue:

You could have written it even longer. Though I don't really know how. :-P

Python is not Lisp. Don't map lambdas.
sum(x+max(0,x-100) for x in fold.values())

Not particularly clear. BTW why not `keys[0] = ''`? And str.zfill method could be handy. :-9

Your matrices obviously aren't. The good question is, why? :-) And more importantly, why do you think this is clear? :-P

It would be much better to use SymPy directly here, not only its results. :-)
And people really should import hypot from math instead of sqrt. :-P

Next time try stackoverflow sort. :-P

There is really no reason for a separate function. Lines 10~22 should just be up there, instead of line 4.
Also, instead of naming the result (with those unfortunate parentheses), it would be better to return it immediately.
if f_result is g_result is None: return None, 'both_error'

You have obviously seen that the origin is irrelevant - after all, you start from 0 for ranks, and from 1 for files. It is much easier if you put origin on (97, 48) - do you know why? ;-)
And why lines 9~10? Special cases are not special enough. ;-)
