follows:
A - one cell in one direction (horizontal or vertical), and then two
cells in other direction (vertical or horizontal) - one such a move is
shown in Figure 2,a;
B - two cells in one direction (horizontal or vertical), and then one
cell in other direction (vertical or horizontal) - Figure 2,b shows
one of such moves.
