Recapping the K&R algorithm from 
the October '82 Bridge World pp. 21-23.

Protected high cards:
    A = 3, K = 2, Q = 1

Shortness:
    void = 3, singleton = 2, doubleton = 1
    Discount first doubleton
    4333 = -.5

Suit quality:
    4321 count divided by 10 * number of cards in suit
    Adjustments:
        Seven card suits:       1 for missing Q or J
        Eight card suits: up to 2 for missing Q or J
        Nine or longer:   up to 3 for missing Q or J
	Six card suits or shorter:
            Ten with two honors: 1
	    Ten with the Jack:   1
            Other tens:          .5  
		(modifier about six-card suits misplaced?)
	    Nine with the ten:   .5 or
            Nine with two honors:.5 or
	    Nine with the eight: .5

short honors:
    stiff king = .5
    doubleton queen if with A or K = .5
    stiff Q or Qx = 0 
    
lower honors:
    Queen if without ace or king and suit is 3 or longer = -.25
    J with exactly two higher honors = .5
    J with exactly one higher honor  = .25
    doubleton queen = .25
    Ten under two higher or with 9 and one higher = .25

Bottom line:
    1H, 1S, 1NT opening optional at 12.0
			mandatory   12.5
    1C, 1D      opening optional at 13.0
                        mandatory   13.5
    2C with major		    22.0
    2C with minor		    24.0
