Hand Types

The nodes representing hand types were given values which divided hands into the seventeen categories of final hands reported in Table 2. This produced a level of play comparable to a weak amateur. Since any paired-low hand (pair of 9 or lower), for example, is treated as equal to any other, BPP would bet inappropriately strongly on weak paired hands and inappropriately weakly on hands such as a pair of nines.
