Opening 2-bids and responses	
Opening 2C (may have multiple meanings):	
    ~23+, game-force unless 2NT rebid	
    strong, 22-23 "total points" 	*
Opening 2D (may have multiple meanings):	
    strong, game forcing	*
Opening 2H/2S: 	
    weak  [ high card points ]	5-10

            5 in 3rd position	*
            6	*
           ditto but only in 1st/2nd position	*
Responses to opening 2 bids	
Responses to 2C:	
2D:	
    negative (< 9 points) 	*
(Assumed that other suit responses show positive values and 4+,	
2NT shows a balanced 8+ HCP and does not deny a 4-card major)	*
Responses to 2D:	
    2H:	
        no aces, 0 .. 6	*
    2S:	
        one ace, 0 .. 6	*
    2NT:	
        no aces, 7+	*
    3C:	
        positive, 5+	* good suit
    3D/H/S:	
        3D/3H is positive, 5+	* good suit
    3NT:	
        two aces	*
Responses to weak two:	
    (Assumed that raise to three is a pre-emptive raise)	
    New suit:	
        natural, forcing	*
    2NT:	
        feature showing 	*
Opening 3 bids	
Assumed that an opening 3 bid shows a 7-carder, possibly 6 or 8.	
5-9 HCP (maybe a point or two less at favorable vul and/or position)	
    Guarantees a minimum suit quality    always	
                                                               if vulnerable	*
Assuming new suit to an opening 3 bid is natural forcing. Game	
bids are to play. Direct raises are to play either "real" or sacrifice.	
Opening 4 bids	
"Good" is assumed to be ~8-9 playing tricks. 	
"Bad" could be KJxxxxxx and nothing.	
"Natural" is ~7-8 playing tricks.	
4C:	
    "good" opening 4H bid  	*
4D:	
    "good" opening 4S bid  	*
4H:	
    natural, pre-emptive	*
4S:	
    natural, pre-emptive	*

If two suits bid, 1NT overcall is:	
    sandwich for a passed hand, strong for a non-passed hand	*
Balancing 1NT overcall:	
    Over 1C or 1D  [ high card points ]	12-15
    Over 1H or 1S  [ high card points ]	12-15
