$10 local bar donkament, what's my line?

[Parallax]

Playing in a weekly local $10 bar SnG with a bunch of loose, unimaginative players.
Blinds are 100/200, this is the 2nd hand. Villian and I both have ~5000 in chips
Villian raises UTG to 400, I raise black queens UTG+2 to 1400, folded back around to Villian who calls.
Flop comes Q [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img]
Villian bets out 1500, what's the optimal line here?
My thinking was to smooth call the flop and push any non diamond turn. As it ended up the turn was a 4th [img]/images/graemlins/diamond.gif[/img] and he pushed. I folded and Villian flashed the J [img]/images/graemlins/diamond.gif[/img] to me...

Just curious how others would play this. Thanks.
