If you implement the moving board by simply covering the squares that are supposed to be holes with an obstacle, as I suggested below, you would not have that problem. You could use draughts chips for marking the holes, but it would perhaps be nicer to have some square tiles of a third color that completely cover the squares.
This is much more likely to work than actually trying to construct a board where all squares can move.
