I woudl raise this flop with every hand I would c-bet if checked to. KsTs is definately in that range, although I wouldf sometimes check behind (preferably with a read that he is going to pay me off when I hit). Against unknown I assume he has mostly trash and raise.

I check the river behind, if he has really nothing, we win and our line does not look strong at all, so i doubt he will fold much hands we beat.

/edit: I also agree with checking a blank turn behind.
