THE BLADDER CARRIER:
Once in possession of the bladder, the player has the option either
to move a piece (including the piece carrying the bladder) or
pass the bladder to another piece.
The bladder may be passed a maximum of three adjacent squares,
in any direction, over the heads of other pieces, as well as open
areas. The three squares may be counted in any way (straight,
diagonally, 'L' shaped, etc.) provided all three squares touch
at either the side or corner (see fig. six).
