[BluffTHIS!]

With that many players in a pot, even though you know one of them must be drawing to a flush/overpair, you are virtually never going to be ahead. You can't beat 77 or 75. And this is a small pot so you don't have diddly for equity to protect. Check and Fold. Against one player only you could check/call to the river, but even then you usually aren't going to like it between the times you are beat and the times someone else with only a 5 hits his kicker and you don't know it.
