Hand shape: the ace is a blocker — it removes some of the aces and big pairs a caller needs and being suited adds flush equity when it is called.
A9s is an edge hand in 12 published spots, where the Nash solution mixes it: 9-max UTG 8bb (37%), 9-max MP 10bb (31%), 6-max UTG 12bb (27%), 9-max UTG 10bb (17%), 9-max MP 12bb (16%), and 6-max UTG 15bb (12%), plus 6 more. In a true Nash mix both options earn about the same against the equilibrium callers, so a consistent default costs little.
