The rule is that the joker moves like the last move of the opponent. This game does not have a castling but it will come to it in other games. Castling is generally considered a king move. There is a king may leap once a game rule. That it. I think the confusion related to when the loan of power ends not when it begins. That happens when the oppnent has just moved. I'm not sure I understand the qustions otherwise/
