Since they couldn't move the chess pieces anymore when it was still in their miniature forms, Allen and Carrion had already known how to move the pieces.
And that was to command their army! They were the kings of their respective armies so it was without a doubt that their army would listen to their command.
"Rook to c2!"
Carrion yelled as he commanded his rook to move to c2.
The black rook moved as Carrion had commanded it to do as it moved to the c2 square.
"Check."
Carrion informed Allen that he was in check.
"King to e1."
Muttering those words, the throne that he was sitting on slid on the floor as if there was no friction on the chessboard as the throne slid towards the e1 square until it stopped when Allen was at the e1 square.
"Bishop takes bishop."
Carrion commanded his bishop to deal with the white bishop.
