Maximal Doubles
---------------

These occur in highly competitive auctions, such as:

	part	opp	you	opp
	1S	2H	2S	3H
	double

The double is used as an invitational bid.  Partner is expected to 
either bid 4S with a maximum, 3S with a minimum or pass for penalties.

A direct bid by partner of 3S is not invitational--- just competitive.


NOTE: The maximal double is used in its original form only when the
	opponents have given you no room to make a game try.  Thus,
	in 1S-2D-2S-3D;  3H would be the game try (nothing about 
	hearts) and double would be for penalty.
