I wasn't sure of the line here.

BB is passive (postflop agg .5). He has cred me on the turn with trips (I was openended). I'm sure I have the Button beat. So do I 3-bet the river and open myself up to a cap getting 2:1 on my money?

man, BBs play is a little goofy to me. Especially for someone who is so passive post flop. I really want to say raise, just cuz his play seems so donk my gut says it isnt a FH, but if I havent seen him do anything stupid before, and that PF agg number is after a reliable number of hands, I think I'd just call.
