Party 50nl; combo draw turn decision

[boardertj]

Villian is 54/11/.5 only 30 hands. Somewhat of a calling station, called down two bets with a weak middle pair on a drawy board earlier in the session.

BB checks, Hero?

In these spots, with strong combo draws that don't hit on the turn, should I be putting in another bet here as a semibluff/value bet? How does this change against a more straight foward opponent who is not so much of a calling station like the villian in this hand?
