And yes a formation of identical chess pieces (2x2) can move as a separate combat unit using four squares of the board (2x2) as one square. But this square (2x2) must be either empty or completely filled with chess pieces. If there are one, two or three chess pieces on this square (2x2), then the movement of the 2x2 formation to this square is impossible. In all other cases, the movement of chess pieces occurs according to the rules of standard chess.
