- efitz 9mo agoHow do you differentiate between "never moved" and "moved but moved back"?
- vntok 9mo agoIf the rook has not ever moved yet, it gets the king's positional value. As both pieces can't overlap, assume the king's positional value is correct and the rook is at starting position. Then, as soon as the rook is moved, it gets its actual positional value. If it moves back later, the positional value will be that of the rook's starting position (guaranteed different from the king's current positional value as the two pieces can't overlap).
