I have an idea that it has been used in most of the Indian Chaturanga variants, even the Thai Makruk uses it as an optional rule. What do you think that in the first move of the King he can jump like a Chess Knight to the left or right, this allows speeding up the Shogi Castles, of course there are a few rules: 1.-It can only be performed on the King's first move (if the king has moved, it can no longer be performed). 2.- The movement is only to move the King, never to make captures. 3.- If the King is threatened, this move cannot be made. I await your comments for this variant.
