2/4 B&M - Spewing all over myself on the river

[gobbledygeek]

2/4 B&M, 10 handed, loose & passive

SB is loose passive old guy. Kind of guy that flops a set and then just calls down if ever raised for fear of monsters.

Button is very loose passive old guy. Will always get to at least the turn with any piece for any amount of bets.

Preflop: Hero is CO with Q [img]/images/graemlins/club.gif[/img] T [img]/images/graemlins/spade.gif[/img]

SB bets, 2 calls, Hero raises, Button coldcalls, SB calls, other 2 calls

Turn (5 players, 8 BB): 4 [img]/images/graemlins/heart.gif[/img]
checked to Hero who bets, Button calls, SB calls, others fold

River (3 players, 11 BB): 9 [img]/images/graemlins/heart.gif[/img]
SB bets, Hero raises...

I'm fairly certain the first 3 streets are standard, it's the river I'm concerned with...

1) Against old passive guy who doesn't seem overly concerned with runner runner flush, can I possibly raise this hoping he was only betting trip 9's?

2) If Button 3bets, is this the world's most easiest fold?
