  • Bonus Challenge: since we can talk about the same position having different boardstates, can we consider different positions to be the same boardstate? If i’m not mistaken, all vertically mirrored positions which transfer castling rights are the same boardstate. in addition, since most pieces don’t care which direction they face, a boardstate with all pawns captured or promoted could be considered to contain all rotations and vertical/horizontal mirrors of that position which preserve castling rights. Is it possible to create a position with pawns remaining which remain the same boardstate when transformed? I think, yes, in conditions with a forced-forced-mating. I think you could even get a pawn capturing diagonally into a checkmate, and it would be equal to a 90 degree rotation.
