River Fold? $200NL on PP

[LordBaldrick]

I just played this hand a few mins ago on PP at the $200NL level. My opponent is an unknown (only logged about 15 hands against him). As you can see I Folded to his reRaise on the River. Despite having a straight, my thinking is that I am only beating a Bluff at this point. The obvious Flush came in on the Turn and the River card paired the Turn card giving the villain a possible full house. Does anyone have a radically different take on this scenario and/or any comments on my bet sizes (they were meant to be blocking/info bets)? cheers
