Structured Reverses   (notes from Root-Pavlicek's) 
------------------- 

Definition of a Reverse: After a one level response, a rebid of a
	2nd higher suit by opener at the 2 level shows 17+ and at
	least 5-4 distribution (5 in opening suit and 4 in second)


Here are some examples of a Reverse (*) by opener:
	1C	1H
	2D* 

	1C	1S
	2H*
	
	1D	1NT
	2S*

	1H	1NT
	2S*


In each of these cases, opener is making partner bid at a higher
level to show support (thus, opener must be strong to force 
responder to bid so high).  After Reverse by opener, responder 
can show weakness (less than 10).  There are two cases: 

1) Responder has bid a major:
	In this case, responder shows weakness by a) bidding the
	major again (showing 5+ in the suit) or by b) bidding NT
	to show that the suit was just a 4 card suit.  Examples:

	1C	1H
	2D	2H*    	responder is weak and shows 5+ cards in H 

	1C	1S
	2H	2NT*	responder is weak and has only 4 cards in S 

2) Responder has bid NT (6-12):
	In this case, responder shows weakness (<10) by 
	a) showing preference (bidding the lower suit) or by
	b) bidding the lowest NT to show no support for the lower suit. 

	1D	1NT
	2S	3D*	responder is weak and has maybe 3+ card support
	
	1H	1NT
	2S	2NT*	responder is weak and has no support for H 
		
	NOTE: never pass a reverse. 
	NOTE: If responder does not make a weakness signal, a 
		game-forcing auction is created.  
	


GAME FORCING REBIDS BY OPENER after a weakness signal:
1) Bidding the 4th suit (always forcing).  If a minor, it shows 
   5-4-4-0 distribution.  If a major, it must be artificial.  
	1C	1S
	2H	2S
	3D*		Shows 5 clubs, 4 hearts, and 4 diamonds

	1C	1H
	2D	2NT	
	3S*		why would opener wait so long to show spades? 
				it must be forcing 
 
2) Show support to a 4 card suit.  After all, why support just 4?
	1C	1S
	2H	2NT
	3S*		you couldn't support earlier, so supporting
			now shows at most 3 cards and a strong hand

3) Bidding the higher suit again to show at least 6-5.
	1D	1S
	2H	2NT
	3H*		you could just bid 3D and let resp choose, 
			but you didn't, so you must be strong.

	1D	1NT
	2S	3D
	3S*		responder has already chosen, so bidding 
			spades again makes no sense if you don't 
			have a game-forcing hand.  

4) Jump in the lower suit to show extreme distribution (7-4) 
	1C	1NT
	2S	2NT
	4C*		shows 7 clubs and 4 spades is forcing			



NON-FORCING REBIDS BY OPENER:
1) Raise of partner's suit (if 5 carder):
	1D	1S
	2H	2S
	3S		You are inviting partner to 
			bid game with a maximum
	
2) Bid 3NT (to play): 
	1C	1S
	2H	2S
	3NT			
	
3) Raise of partner's raise:
	1D	1NT
	2H	3D
	4D*		asks resp to bid game with maximum 

4) Bid 2NT to show 4th suit:
	1C	1H
	2D	2H
	2NT		shows you have a spade stopper
