River play, top two pair sees flush draw hit

[graarrg]

Usually I wouldn't even give the villain room to make a bluff bet in the few scenarios that he would have to. Continue to bet out. More passive players will not attempt raising as a bluff because they know that it is very possible that YOU have a flush or even a HIGHER flush. Unless he makes the nut flush, at the low limits, he will just call... but never risk it all.
