Skimmed a few responses- as others have mentioned the limp/cap means nothing. Victor calls this guy "Random four bet dude". PP's are favorite hands for them to do this with. so is 95o, what ever you know knowthing preflop.
As far as the flop and turn, its heads up, no overlay from osmeone else, i usually slo down after he raises the turn. 66 is what his hand looks like to me, either that or air. Let him bluff. If you've played with him a lot and he will way over play QT like this here then i am much more in favor of the three bet, with no read that he goes overly nutso i just call down.

Secondly, what do you think about calling the flop raise and donking the turn if hes aggro (1.5 ag with 65 vpip looks like). You aften have BB drawing thin to dead and can pick up another 1.5 BB's from him.
