River action?

[PoorLawyer]

I probably crying call here. He would raise with a straight or backdoor flush, but does he put you on more than aces up? I doubt it given the limp and the fact that he's a fishy. He only has to be raising lower trips a small % of the time to make the call worth it....there is also that .5% chance he is trying a desperation raise bluff if he has since you make tough folds like this before.
