In chess when a player castles they swap Rook with King (Trump with military). Rooks are considered endgame pieces, hence they are major pieces as opposed to minor. Castle Rock could be interpreted as both, Castle Rock Entertainment and Castle Rook, the swap, a play on words.
This theory may have already been discussed, but if we are playing 4D chess, then the endgame would be a chess move... a move no one saw coming until now.
I never said it was called Castle Rook, did you even read my post? I said 'castle', it was a play on words, combining two sets of theories. It's hardly a stretch, 4D chess, Castle, Rock (who the hell knows what that means in reference to all of this), endgame piece, swapping king (Trump) with Rook (military), yada yada. It mihgt be a bit to on the nose quite frankly.
