So opponenet is very nitty player. Cbets flop 75% over this sample.
I am wondering if i should call here again? Not that many FD's given the A 
is out there. He still has all overpairs.
Do we make exploitable fold vs nit? Or do we call this and possibly try to bluff river? Or is checking back enough?
