Common annoying spot: c/minraised on flop w/marginal hand

[Halv]

SB ($576.60)
BB ($392)
UTG ($601.60)
MP ($421.20)
Hero ($464.30)
Button ($439.30)

Preflop: Hero is CO with 9, 9.
UTG calls $4, 1 fold, Hero raises to $18, 3 folds, UTG calls $14.

Flop: ($42) 2, 3, 6 (2 players)
UTG checks, Hero bets $30, UTG raises to $60

Assuming hero has a standard TAG-ish image, how do we proceed in this spot vs an unknown? What about a loose/semipassive donk (like 40/10/1.5)? Against a maniac (60/30/3)?

I tend to call, planning to call again on blank turns and probably fold the river. This is landing me in tough spots alot though, since there are so many scary cards and the villain usually gets to see both streets. Alternatives?

i dont bet the flop and play the turn and river like fmost people flop and turn

[IowaSkinsFan]

call, see if he wants to play for stacks, and if he does fold, if he doesnt play for stacks.

re-raise and re-evaluate

Why wouldn't you bet this flop? So many worse hands are calling

As played, I play it the same, call the min raise.. probably call a turn lead and see what happens on the river.
