set on scary board

[jpsnow]

Should i fold to this river bet? I couldnt really put the guy on a hand other than some sort of draw. If he had the straight he woulda made it on turn but why wouldnt he reraise on that board? I can really put him on the flush draw that hit the way the hand played out, but i guess thats a possibility too. Opponent is 20, 4.6, 2.49

Please don't make this fold. 8hth, 8h9h, are really only hands he could have that beats you.

A backdoor flush coming in and a straight getting there are not THAT scary. This could be a decent ace or busted diamonds.

Bet more on the flop, I'd say $5.

Pot the turn.

Call the induced bluff on the river.
