Iso raise..not so good.

[Bilgefisher]

My opponent seems fairly weak. He limps with a few hands. I don't think his raising standards are overly tight, I just don't think he's had any great cards. He has called down with marginal holdings but is willing to fold. I understand zeebos theorem plays into affect here, but my question is do you think I have the odds to call his bet on the river?
