given the read on villian i would fold here.
im not saying your behind at the moment for sure but i think his range for this play can be anything from an overpair to something like AKh AQh AJh.
if he has any of them his got something like 14 outs which makes it a very starong draw.
i think you playd the hand well ,but his saying he has a better hand and considering the blinds are 50/100 you can affrod to let this go.
