25nl turn it into a bluff vs fish?

villain is 65/0 over 50ish. he limp/calls any two suited pre. has folded to 2/7 cbets and dumped his hand on later streets a lot of the time he's called. the rest of the table are nit regs. i feel he's getting to the river with a heap of hands like mine - missed pair+draws, 8x, 7x etc - and not many J's or Q's. turn it into a bluff or check it back?

SB checks, Hero?

edit, also what do we think of turn bet? i would bet like $3 on it with air and expect villain to fold a lot of the time given what i've seen of him. on this occasion i decided to bet smaller for thinnish value and to build a pot to own him on appropriate rivers, bad logic?
