400nl, c/r bluff, worth risk?

6max 2/4nl eurobet, villain is button with 500, he's been 3-betting preflop liberally and giving up postflop enough this session that I think he's pretty light here alot of the time. He may or may not be on tilt.

If he's paying attention, he'd think of me as weak tight since the previous hands we've played together ended oddly.

Hero (500$) opens UTG to 12 K [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/club.gif[/img], villain makes it 32$ on the button, Hero calls.

Flop: 4 [img]/images/graemlins/spade.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] 9 [img]/images/graemlins/spade.gif[/img] (70$)
Hero check calls 55$

Turn: T [img]/images/graemlins/diamond.gif[/img]
Hero checks, Villain bets 100$ really fast, Hero c/r's all in

I don't open UTG w/ KQo.

i guess check/calling the flop is okay. I don't think I'm calling w/ a gutshot & the flush draw, I'm not getting paid off here with many hands when the flush card lands.
