sentence in the problem statement:
From a cell (X, Y) the new piece can move to any cell of the chessboard such that its color is different from that of (X, Y).
From this statement, it is not clear if the piece can move (1,1) to (6,1) in 1 step.
Understanding this missing info is critical to solve the problem.
So, better to add clarification.
