SPMK flop and river decision

[rzk]

villain (CO) is 22/12/276 no reads
others are loose passive

flop line ok? what should i do on the river. i'm definitely behind his range but if i check and he bets i probably don't have a profitable call. so b/f or c/f?

Whats his post flop aggression like?

Without any reads I can't check fold this river, and I like b/f a lot better than c/c so I bet.

tough spot. Q9...probably not. I think even if he has a some kind of worse hand, like PP with club/Ax, I think he's checking. c/f
