(Bluff)raise this river?

[Tyler Durden]

From the Super Tuesday. BB is 100. I have 1600. Villain has 3900.

He minraises UTG. His play has been reasonable but he's been liming a lot, once he openlimped w/ J7s in EP.

I have J[img]/images/graemlins/heart.gif[/img]J[img]/images/graemlins/club.gif[/img] in EMP and coldcall. Heads up w/ 550 in the pot.

K66 two[img]/images/graemlins/heart.gif[/img]. I check behind.

Turn 2[img]/images/graemlins/heart.gif[/img]. He bets 100 and I call.

River is an offsuit 8. He bets 100 and I.....?

Thoughts appreciated.
