So you made a .5psb and left yourself with 2550 after the bet. The pot is 1k, you are getting 2:1 on your money at the moment. You figure he probably has 2pr here (maybe staight, but you have a 5). On the turn, there is pretty much no card (other than a 2 or 3) that isn't helping you or possibly slowing him down. I think that live I would call and see what he does on the turn. The fact that he can make big laydowns does dissuade me some from calling this raise if he will fold if the 4straight gets there. I think I make the call on the flop (leaving me with 2k in a 1500 pot) and see what happens on the turn.
IF your read goes that strong that he has a big hand I can find a fold here.
