Recommended move, or pressing my luck?

Full ring table that has yet to fill up.
4-handed.

Villain is a loose gamber, but still solid in this regard; I think he plays like this to blend in with the friday and saturday drunk fest.
The only history was from last friday, where we were at a full ring table which doubled as a drunken melee. We weren't involved in any hands but he mightve noticed me build up an impressive stack picking my spots well with the maniacs. (One memorable quads hand where I stacked two players)

At this table, I first doubled up with AA vs. his JJ AI preflop, and then stacked him again in a standard overplayed TPTK against my set hand. Shortly after he doubled up against me when I pushed an OESD plus flush draw and he called with the same higer flush draw with two overs and the flush hit oddly enough.

Villain - 170 BB
Hero - 350 BB

Hero on he button with

Villain limps, Hero makes it 4BB to go, blinds fold, Villain calls.

Flop is :

Villain leads out for half pot, I raise 2/3 pot, Villain calls.

Pot: about 50BB

Turn is:

Villain leads out for half pot again, Hero puts Villain AI.

Looks OK, I think. Odds are good that he's behind on the turn and if so you may as well take down that fat pot now. If he calls he's probably not far ahead of you. His play is a bit unreadable - hard to tell if he has a pair of nines, two pair, or what. A straight seems somewhat unlikely, and a set more so - if he had a set it would be normal to three-bet the flop with so many obvious draws out there, and you showing a lot of interest. J9 is possible and unwelcome, but you would still have 12 outs. My thought reading through the hand is that he has A9 or T9 a lot.
