50NL- AJ 3 handed line check

[BPMaR]

Nl holdem 50NL ( 3 players)

Reads: Villain is Loose passive aggressive, only raises premium hands AK+, JJ+. Raises flop 3 times with the goods (2 pair, OP, TPTK). Hes not good thou. Raised hero's cbet 1 hand ago on a kTx 2 suit flop, I think he views me as a bully.

My image TAG Since it got 3 handed I have raised every hand for the last 3 hands and cbet flop, ( got decent hands in a row)

BB (48.19)
SB Hero (56.08) (J[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/club.gif[/img])
BTN Villain (77.15)

Pre flop
BTN limps, Hero raises to 2.45, 1 fold, BTN calls

Flop (5.40)7[img]/images/graemlins/club.gif[/img] A[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/diamond.gif[/img]
Hero bets 4, BTN raises to 10, hero calls

Turn (25.40) 2[img]/images/graemlins/diamond.gif[/img]
Hero checks, BTN bets 15, Hero goes allin for 43.88

I feel he has a weak ace, possibly also turned a fd, and doesnt think I have ace . I believe I am ahead here most of the time, (he didnt raise the full 3x on flop, so monster or weak ace). Does my assumption and actions make sense ? Is there a better way to play the turn?
