Chinese Poker with 2-7 middle hand distribution

Back, Middle, and Front distributions from 10M CP hands set to maximize value. Each file contains hands found, worst to best, with the number of instances found in 10,000,000 hands, and the percentage of hands equal to or wose the current hand.

The two data sets here differ slightly because they are exploiting slightly different strategies. A strategy "B2" was found which maximally exploits the hands in data set "2". Then data set "3" was generated to maximally exploit "B2" by changing about 2% of the arrangements, using the same set of hands as "2".
