Traffic Lights:Green, Amber and Red are
used to rank and weight 2-card hands based on probabilities of winning games. The system gives each card a score.
Extra points are given for:
Pairs, Suited and Connected cards.
This is justified because it increases the Ways-of-Winning and the number of outs. A pair-in-the-hand often wins the game. Having
Suited Cards increases
the chances of a Flush. Connected Cards increase the chances of a straight. Having two Court Cards
increases the chances of getting a high pair. The scoring system is based on the probabilities of winning with a hand of two cards.
See Resources for analysis of how the hand scores relate to the probabilities.
