So I did call down my hand, which is OK I think from both balance perspective (top of my x/c range) and from exploitive perspective (my opponent bets too much).

But what Im interested in, can I make some presumptions of his range by his betsize?

He is betting almost pot bets on turn and river on very dry board which Im inclined to calldown with most my Kx hands. So it makes little sense for him to bet that big with a bluff unless he just does it because that is his style of play.
