s2 = shape(north, any 11xx) ? 3 : 0
d1 = shape(north, any 2xxx) ? 1 : 0 // allow for 3 doubletons
d2 = shape(north, any 22xx) ? 1 : 0
d3 = shape(north, any 222x) ? 1 : 0
shortSuitPoints = v1+v2+s1+s2+d1+d2+d3

h = hearts(south)
d = diamonds(south)
c = clubs(south)
oS = s>4 and s>=h and s>=d and s>=c and not (P1 or P2)
oH = not oS and h>4 and h>=d and h>=c not (P1 or P2)
oD = not (oS or oH) and ((d>3 and d>=c) or c<3) not (P1 or P2)
oC = not (oS or oH or oD) and not (P1 or P2)
openingSuit = (oS or oH or oD or oC)

Define opening Major and opening Minor

oneSpade = oS
oneHeart = oH
oneDiamond = oD
oneClub = oC
oneMajor = (oS or oH)
oneMinor = (oC or oD)

Define 3+ card Fits for south

hFit3 = oneHeart and hearts(north)>2

Define 4+ card fits for south

sFit4 = oneSpade and spades(north)>3
hFit4 = oneHeart and hearts(north)>3
majorFit4 = sFit4 or hFit4

Define Good suits -- 5+ cards with 2 of the top 3

gS = spades(south)>4 and top3(south,spades)>1
gH = hearts(south)>4 and top3(south,hearts)>1

All of the following is for calculating the suit ranks for North opener, East overall, and South new suit

Predict North's opening suit

sN = spades(north)
hN = hearts(north)
dN = diamonds(north)
cN = clubs(north)
nS = sN>4 and sN>=hN and sN>=dN and sN>=cN
nH = not nS and hN>4 and hN>=dN and hN>=cN
nD = not nS and not nH and ((dN>3 and dN>=cN) or cN<3)
nC = not nS and not nH and not nD

Calculate North's Rank

nRS = nS ? 4 : 0
nRH = nH ? 3 : 0
nRD = nD ? 2 : 0
nRC = nC ? 1 : 0
northRank = nRS+nRH+nRD+nRC   // all except one are zero

East's longest suit for overcall

sE = spades(east)
hE = hearts(east)
dE = diamonds(east)
cE = clubs(east)
eS = sE>=hE and sE>=dE and sE>=cE
eH = not eS and hE>=dE and hE>=cE
eD = not eS and not eH and dE>=cE
eC = not eS and not eH and not eD

Calculate East's Rank

eRS = eS ? 4 : 0
eRH = eH ? 3 : 0
eRD = eD ? 2 : 0
eRC = eC ? 1 : 0
eastRank = eRS+eRH+eRD+eRC

South's longest suit for responding in a new suit at the 2-level

s = spades(south)
h = hearts(south)
d = diamonds(south)
c = clubs(south)
sS = s>=h and s>=d and s>=c
sH = not sS and h>=d and h>=c
sD = not sS and not sH and d>=c
sC = not sS and not sH and not sD

Calculate South's Rank

sRS = sS ? 4 : 0
sRH = sH ? 3 : 0
sRD = sD ? 2 : 0
sRC = sC ? 1 : 0
southRank = sRS + sRH + sRD + sRC

Requirement for a Free Bid, Negative or Otherwise

(northRank > eastRank) or (eastRank > southRank)
