I don't think I can c/c this flop OOP. While his raising range is pretty wide, I may be ahead, or it could be a better ace / PP. At any rate, I decided that it would be too expensive to figure it out and folded to find a better spot. Comment on the flop line if you see fit, but my main question is do I repop PF?

Thanks in advance for all comments.
