Flint 3D, 3C, and 2D 
--------------------

{paraphased from "The Official Encyclopedia of Bridge" (1984)} 

Flint 3D:
	over a 2NT opening, a 3D response demands that opener bid 3H
        which responder may pass, bid 3S, 4C or 4D as signoffs.  
        Other rebids (say 3NT or 4H) by responder are mild slam tries
        with a real diamond suit.

Flint 3C: 
	This allows the partnership to play in 3D. A 3C response 
	demands that opener bid 3D which responder may pass or bid a 
	long suit as a signoff.  A 3D response is then Stayman.  This 
	convention is similar to Gladiator (q.v.).

Flint 2D:
	After a weak no trump opening, a response of 2D is used to 
	invite game in NT or a minor suit.  Responder has either: 
	1) a long solid minor, or 
	2) unbalanced hand with at least four cards in each minor
 	
	If responder has (1), responder rebids 3C with a solid club 
	suit OR a solid diamond suit plus a club stopper, or responder 
	rebids 3D with a solid diamond suit without a club stopper. 
	If responder has (2), responder rebids his stronger major.

	The 2D response is forcing to at least 3NT.  Opener rebids:
	* a four card major, or
	* 2NT without one 
	Over responder's rebid, opener may bid 3NT, show a stopper, 
	signoff in four of a minor, or bid a minor suit game.
