I'll take a look at it if I have time, my focus is on getting #65 flushed out. If someone takes a look at this before me, one thing to remember is "Two positions are by definition "the same" if the same types of pieces occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture en passant is the same". Castling rights and the possibility of en passant are the obscure rules that often get left out.
