there are stats such as aggression facotr, aggr. frequency, etc.

hes not bluffing here if we assume hes passiv. so he either has flush. fullhouse or at lowest ak. tx is discounted of his range if he isnt crazy or sth. he might overplay (?) hands such as aq sometimes, but aq is only 6 combinations and aj 8 comibnations.

if hes aggro i would call.

This guy looks fishy and passive so it`s kinda over-elaborating to think he`s gonna barrel anything else other then Ax KsQs QsJs.

Even though this looks like a trivial call on the surface, i think a case can be made for folding due to his passiveness and low pfr% which means he doesn`t show up with worse aces here much when opening Utg.

Defo include postflop stats as @1followu mentioned.

he doesnt show up with many aces cause he wouldnt bet them small/thin for value and would just check them since hes passiv. and like i said they small part of his range compared to hands that beat us.

u have to think about how he views ur range aswell. and cause obviously hes a bad handreader he thinks u can easily have tx or a (in practice very unrealistic) backdoorflush.

I would call. I think if he had a monster hand hed be betting bigger most of the time and he gave you such a good price that I think AQ is a call, especially holding the As. I dont see any read that suggests hes super passive either.

If the gap enter his vpip/pfr is due to a limp range, then his value range is really narrow, something like "AcAh,TdTh,AhTh,KJs+,QJs"= 6combos, and even if he raises ATo, it's add only 2 combos so with such great pot odd it's difficult to find a fold since he really don't need to bluff often. (note: I consider AK as a check with the flush and the second T river. And assume he limp 66, 89s ... but if he does't have a limp range, we can add these)

So with just the PF info I would call but I think here the postflop stats (such as CB f/t/r, donkbet, check/fold, bet river) are important to evaluate his aggro and take our decision like if he is CBetting 50/40/40 I just snap fold obv ^^ but if show aggro stats post flop, I would snap call with the pot odds.

Since this hand I collected few more hands about him.

Cbet OOP f/t/r: 92(12)  100(5)  25(4)

His sizing really makes it look like a scared value bet.
I'd never ever fold here, and expect to win vs worse Ax, chop with AQ a lot, and occasionally lose to AK or some kind of inducing hand.
