Hand shape: as a connector it can make straights in both directions and the weak offsuit kicker is often dominated when called.

98o is an edge hand in 8 published spots, where the Nash solution mixes it: 6-max BTN 10bb (56%), 9-max BTN 10bb (56%), 6-max BTN 8bb (89%), 9-max BTN 8bb (89%), 6-max SB 20bb (93%), and 9-max SB 20bb (93%), plus 2 more. In a true Nash mix both options earn about the same against the equilibrium callers, so a consistent default costs little.
