Aganju: As a player is not allowed to occupy all six points of his starting quarter (1-6 or 7-12) at the same time, it is not possible to move in your case from 12 to 7 in 2 moves, as it would mean that you would occupy all six points of the starting quarter between the 2 moves. For this it would be necessary that people would be allowed to move 2 pieces in one, to prevent to occupy all six points...
