Does potodds justify a call here?

I thought it was very possible that opp had the flush, but I thought that pot odds justified a call ($5 for a $28.5 pot). What do you think?

Final Pot: $28.50

Bet $10 into the $6.50 pot on the turn and you won't have the problem. The trend of the draw presented itself on the flop, and then a total blank hit the turn.

Ideally, I like to check raise that flop with that many people in and take it down immediately. You misplayed this.

As for your question, I would probably fold the river. Pot odds or not, I'm almost 100% sure the guy has a flush in that spot. It's just bleeding money IMO.

If you don't check raise the flop, I would push on the turn. Although taking it down on the flop is definitely the best way to go on a board like that.
