How A8s compares

Suitedness is worth 35 extra shove spots here: A8s is a shove in 150 of the 225 solved spots, A8o in 115. From the 6-max Button A8s shoves up to 24bb and A8o up to 15bb.

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.

A8s is an edge hand in 13 published spots, where the Nash solution mixes it: 9-max MP 8bb (37%), 6-max UTG 10bb (22%), 9-max UTG 8bb (20%), 9-max MP 10bb (14%), 6-max UTG 12bb (12%), and 9-max UTG 10bb (11%), plus 7 more. In a true Nash mix both options earn about the same against the equilibrium callers, so a consistent default costs little.
