Black Kings gaybet on a scare card

[kurosh]

Hypothetical situation. 5/10 or above 6-handed. TAG UTG raises. You 3-bet black kings on the button. Everyone folds and he calls.

Flop is 8[img]/images/graemlins/heart.gif[/img] 5[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/heart.gif[/img]
Check bet call.

Turn is A[img]/images/graemlins/heart.gif[/img]
He bets. What's your move?

Different situation: He raises your flop bet, you 3-bet and he gaybets the turn. What if he raises, you call and then he bets the turn?

I'm thinking raise all of them but the first one is close between raise and fold.
