Fourth Suit Forcing 
--------------------

Unless either partner has bid NT earlier, everytime a new suit is 
introduced, it is forcing.  Now, after three suits have been bid,
the fourth suit may or may not be "real".  Sometimes, you get those
hands where it is real and you can't support partner, so you bid
the fourth suit "real".  But other times, you don't know which 
suit to support partner or whether you should be in NT or you think
any other bid wouldn't "show" your hand (ie a raise would show too
many trumps).  So, the 4th suit is a bid of convenience.  


4SF can be either: 
	1) forcing to game or
	2) inviting to game 


	For our purposes, 4SF is (2) inviting game.  Thus, a 
	direct jump is used to show a game-forcing hand.  


	After this sequence:
		Partner	You
		1H	1S
		2C	?? 
	With each of these hands: 
	     1) S: AKxx	     2)	S: KJxx      3)	S: Kxxx      4) S: xxxxx      
		H: Ax  		H:   		H: xx  		H: KQ 
		D: Txxx 	D: AJxxxxx	D: Qxxx		D: xxx
		C: Qxx 		C: Kx		C: AQx		C: AKx

	You could bid 2D.  
	1) The hand could be played at NT, Clubs or Hearts.  You don't know.
		Your 2D doesn't really need to show a stopper.  If you had
		one, wouldn't you  have bid 2 or 3NT? 
	2) This is pretty obvious--- just showing where your points are
 	3&4) You could have raised, but a raise shows 4+ support, so you 
		bide time and bid 2D.  
	

Partner responds to 4SF by: 
	1) bidding NT with a stopper in the 4th suit
	2) supporting a previous suit of partner's 
	3) rebidding the second suit to show extra length
	4) rebidding the first suit to show none of the above
