1/2 NL facing overbet on the river

[LearnedfromTV]

whoa wait, are you not krantz AND not the other guy?

I think this is a fold, and asking if it would be a fold if the flush hadn't come is misleading because he wouldn't have bet doublepot if he didnt make his flush.

Also, you should definitely bet the flop and probably raise the turn. They rarely have anything, you probably have outs if they call, and your draw sucks if they raise so you don't mind folding it.
