personally, i like it. i dont want to see another card w/ such a vulnerable overpair. i cant see him calling you unless: 1) he has another overpair, 2) made straight, 3) set, 4) big draw or combo, and i guess 5) two pair.

that sounds like a lot, but its a limped pot...anything is out there. i like using your FE to push him off or keep him from chasing overcards...which is where my thoughts go backwards, as you want these to chase. you are 70/30 over random hands...which is not too much wider than what would complete the small blind, imo. but, the main issue is how vulnerable your 99 is to T+ on the turn. so, i still like the AI.

however, against a sb, i like a raise pf here. that may help you cut out complete crap like 73o. and he has crap pf here, or he would have tried to steal your blind.
