what to c-bet in 3bet pots?

[Orsman]

3bet with a big pairs from blinds get a caller and then the flop is full of overcards, flushdraws etc. This is a pretty common spot that I get into (and probably everyone else) and I have no idea how to play them. (all hands are 100nl)

I which hands do you c-bet, c/c, crai or just c/f

Hand 1:

Villain is 18/15/2.5 ~600 hands. No 3bet history, 22% attempt to steal

BTN: $139
SB: $104.80
Hero (BB): $100
UTG: $102.95
MP: $100
CO: $99

Pre-Flop: J[img]/images/graemlins/spade.gif[/img] J[img]/images/graemlins/heart.gif[/img] dealt to Hero (BB)
2 folds, CO calls $1, <font color="red">BTN raises to $4.50</font>, SB folds, <font color="red">Hero raises to $16</font>, CO folds, BTN calls $11.50

Flop: ($33.50) A[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/heart.gif[/img] (2 Players)
