The pieces move as follows, with the number per player: 1 x Shah (king): moves one space orthogonally or diagonally. 1 x Fers (counselor): One square diagonally. 2 x Rukh (rook): Any number of spaces orthogonally. 2x Dabbaba: any number of squares diagonally. 2 x Pil (elephant): Two squares diagonally, jumping over the first. Cannot capture another Pil. 2 x Asb (horse): Moves as a Chess knight. 12 x Sarbaz (soldier): Moves one space forward orthogonally; one space forward diagonally to capture. No en passant.
