Ditch this hand pre-flop from UTG. Problem solved.

Since you played it, I think this is a reraise or fold situation. With the texture of this flop I would lean towards a fold, especially since this is not a large pot. If the pot were larger and the board not so coordinated, a 3-bet might be in order.

Also, consider that the action is coming from the blinds in an unraised pot. They could have a number of hands that connect well with this board, whereas if the action was coming from early or middle position limpers you might be able to narrow down their range a little better.

All-in-all, I say it's a not-so-tough fold. If you later find out you would have won, no big deal in this small pot.
