50 6max - basic set play OOP

Villain is a very normal player, 32/5/1.9, who seems to have loosened up a bit due to his larger stack. I've only watched him play for a bit, but he seems to raise a bit liberally preflop (not much) and try to take it on the flop, but shuts down if given heat. I get the notion that he is "playing out his rush" or some nonsense and am just waiting to stack him a couple of times as I'm seated to his direct left. Unforunately, the one hand we clash is the one where I'm OOP.

This is pretty basic I guess, but whats your default line here?

Party Poker No-Limit Hold'em, $ BB (6 max, 6 handed) converter

CO ($191.79)
Hero ($49.90)
SB ($39.55)
BB ($8)
UTG ($61.30)
MP ($38.86)

Preflop: Hero is Button with 9, 9. SB posts a blind of $0.25.
1 fold, MP calls $0.50, CO raises to $3, Hero calls $3, 2 folds, MP calls $2.50.

Flop: ($9.75) 2, 5, 9 (3 players)
MP checks, CO bets $3, Hero calls $3, MP folds.

Turn: ($15.75) 6 (2 players)
CO bets $3, Hero raises to $10?

Was pretty sure he'd shut down on the flop if I popped him there, but I'm probably not getting much more if he doesn't call there. Anyone call and lead the turn? Gimme some basic lines please [img]/images/graemlins/smile.gif[/img]
