That board is really wet so i hate the idea of checking. A bet is a must imo. If he raises it's an easy fold. The tricky part is if they just call. If they lead out on the turn i would fold more times then not. If they check the turn bet again. Now if they c-raise you just ran into a set or better. Play the river almost the same as the turn except if they they check just check behind. If the river is a brick and they lead out well now you gotta ask how often do they bet busted draws on the river. Folding flop is not such a bad option either. Playing under pairs can be a real bitch.
