pub fn cccc(hand: Hand) -> f64Expand description
Kaplan–Rubens CCCC (“Four C’s”) hand evaluation
This is the algorithmic evaluation by Edgar Kaplan and Jeff Rubens from The Bridge World, October 1982, implemented after the 26-step description reproduced by Richard Pavlicek. Scores range from −0.50 to 35.60 in steps of 0.05 on a scale comparable to HCP (mean 10.77).
CCCC weighs honor placement together with shape, which makes it
particularly accurate for suit contracts. Prefer FIFTHS when
evaluating toward notrump, especially 3NT.
