25-50 3rd barrel?

[AbelM]

25-50 3 handed on UB. I start hand with 5000, villain covers. He's been playing somewhat passively, I might've been raising a bit too much (at least that's what it might look like, been catching some good hands).

Button folds. I raise 7[img]/images/graemlins/club.gif[/img]5[img]/images/graemlins/club.gif[/img] from the SB. BB calls.

Flop comes T[img]/images/graemlins/diamond.gif[/img]8[img]/images/graemlins/club.gif[/img]6[img]/images/graemlins/spade.gif[/img]. I pot, BB calls.

Turn comes 3[img]/images/graemlins/heart.gif[/img]. I pot (??), BB calls again.

River comes J[img]/images/graemlins/diamond.gif[/img]. Pot is 2700, i have 3700 behind. Fire again? If so, how much?
