Villain is an OK regular. 15 rfi EP, somewhat agressive cbetting frequencies(70) on 3k hands.

I would probably raise turn something like half the times with my AQ combos, not sure what I would balance it with(suggestions appreciated), but I think villains range will be very strong at this point. I wouldn't raise anything else for value OTT.

In this case my river range will contain a lot of strong hands, probably KQ is the bottom of my range.
I felt pretty bad when I saw this size, and I think worst hand he would bet for value is fullhouses(straights should bet smaller), and I don't even see what he could bluff other than KTs probably.
Would you be able to fold here?
