In the diagram, there is a $4 \times 8$ chessboard. A piece is placed on the bottom-left cell $A$ of the chessboard. The piece can only move one step to the top-right or bottom-right in each move (for example, from $C$ one can move to $D$ or $E$). Determine the number of different ways to move the piece from $A$ to the top-right corner $B$ of the chessboard.
