miller SSHE says in its tighter tables (3-5 callers average) to never play a 9 that is not suited or in a pair. so do not play A9o (other than obviously for free in big blind).... i think in the loose table, it might have just got into playing A9o, K9o but can not remember.... again, do not have book in front of me, but it says to play any suited cards out of unraised small blind (cant remember if it was loose or tight table or both. i think it was both).
