How often is this a bluff?

[unglee]

2-4 NL 6-max, Villian has 400, Hero has 400.

Villain is LAG preflop, raising a lot of hands. Haven't seem him show down anything yet, but doesn't seem too tricky postflop.

Villian raises to $12 UTG. Hero calls in MP2 with QTs, button, SB, BB call.

Flop is T33. Villian raises 30, Hero minraises 60, everyone else folds, Villian calls.

Turn: K (now the board has two to the flush). Villian leads out for $100.

What's your move? What do you put him on? And how much do you hate the miniraise?
