This is a good problem, but it needs more test cases. There is no test with the King for instance, and there should be a true and false state test for every piece.
this doesn't take into account captures or moving a pawn 2 moves from its starting position. should it?
and the occasional other weird rules...
Captures and pawn 2 moves and castling and such aren't possible based upon the assumptions I stated (i.e. no other pieces on the board, the previous move was valid, etc)
