Villain and hero are 100bb effective, not too much info on villain other than he is full stacked and seems to be playing reasonably. assume he is some sort of thinking player

Bttn opens to 3bb
Hero raises to 10bb w 64 spades

Flop KdKh6d, Hero C-bets 6.50 into $19.50(im doing this with my range on this texture) villain calls. Turn 2s

Hero Checks
Villain bets 15bb into 29.5bb

Hero calls

Basically, i am curious how yall view this spot. It seems like villain can have a wider range given my flop sizing. It's hard to tell how much wider because some people will not widen their calling range too much while others will dramatically. I find in this situation i am hardly ever good getting to the river, either facing another bet on river or villain having me beat on turn. It makes sense to me to call the turn given how many hands villain can show up with. Everyone else here calling, anyone folding? anyone playing flop differently?
