Villian is an somewhat aggresive reg 26/21/11 postflop aggresion factor 45% (300hands)

What do u think of flopstrategy: bet with high frequency and dont bet to big because they can have sets and flushes? Or would u like to go bigger?

This is intresting because he doesnt have a lot of bluffs, because i have the Ac in my hand.
My pot odds are 31%, 8 outs (16%) are drawing me to the nuts, 3 outs Ah/As/2C (6%) are improving me but not to the nuts. Lets say i have 20% to improve and beat him. He still needs to have 11% bluffs or combos in his range that i can beat. Does this mean i have to find 5 combos? I forgot how to calculate how many bluff combos he need here. Can someone explain me? I really cant find bluff combos, so i think I already have to fold here. Or he has to do this with JJ then i can call, but dont see that happening.

He is saying i have a flush, and wants value from my overpairs. I think its impossible he will bluff with this sizings. If so I will tell him please go to nl500.
