Optimal line with tptk when scare cards hit?

Against an avg villian 23/17 agg 3 no specific reads

Whats the optimal line to take on the turn and the river with AcJc on Js7s4h flop in following situations assuming you raised pre, c-bet flop oop and he called in position.

Situation 1 - The turn is Qc (overcard to your pair)

Situation 2 - The turn is 2c (blank) you bet he calls & the river is 6s (draw hits)

Obviously in depends on the villain, and other factors, but the vast majority of the time I would recommend B/F.
