       --criteria=
		 A  list of criteria to apply to each generated hand to generate specific hand types.  The list should be space separated and each

       --probability=factor
		 Generate  hands matching the criteria with only the given probability. Factor is in the range 0 to 1. On each attempt to generate
		 a board it is rejected if it doesn't match the criteria with the given probability.  A factor of about  0.8  gives  roughly  half
		 matching boards
