As soon as a piece has reached the far end of the board, it may
be turned about face (literally) - and moved back towards its own
end of the board. This new direction is counted as forward Ð and
again, these pieces can move in any direction except backwards (i.e.
against the way they are facing). If a piece subsequently returns
all the way to its' own (original ) back line, it may be turned
about face yet again - and move forward in the usual way. This turn-around
tactic may be employed indefinitely. The squares which protrude
at the sides of the board (two on each side) have the same practical
use and value as all the other squares. These squares serve to 'open
up' the mid-field playing area, allowing more freedom of movement
than a traditional chequerboard configuration.
