Pyhtheas is 55/5/3.2 with 6.0 river aggression (15 river hands)

I felt checking the flop was OK because he never folds to cbets and he raises a lot of cbets. on turn i thought a lot of hands can call me with pairs&draws etc so i lead. what do we make of this turn minraise? like a discussion yesterday it seems this would NOT be called a belluga. I also hav an OESD so i gotta call and see a river.

river comes total blank. im not sure leading is great on this river because really if he was bluffing he'll fold, and he's not calling that often with Jx i think, more likely if i bet this river and get called I'm beat. If he was bluff raising the turn i can bluff catch by calling here - right?

the problem is his bet is huge. HOW do you decide if you call this or fold?
