55 NLTRN: TP vs possible overpair

[teteatot]

Blinds are still at 10/20, villain is a small winner over a small sample size on sharkscope. This is only maybe 10 hands in, and I have absolutely no reason to believe villain is crazy.

I get Q [img]/images/graemlins/spade.gif[/img] 9 [img]/images/graemlins/spade.gif[/img] and raise to 60. Villain reraises making it 80 to go. I call.

Flop 9 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/club.gif[/img]

With the pot at 280, villain bets 200. I decide to play it cautious and call, seeing if he'll slow down on the turn or if I'll improve.

The turn brings 8 [img]/images/graemlins/spade.gif[/img]

Villain bets 400 at the 680 pot and I fold.

Do you think this is fine, or too passive/tight?
