why are you betting flop?  I am actually asking, not saying it was a bad play.  It seems like you are betting to bet, not exactly for value, not exactly a bluff.  There are some situations against some payoff wizards where betting here could be for value, but they are far and few between.  I do like betting this flop as a bluff instead of checking and betting turn if he checks because by betting we can rep all the turn cards that complete the draws, where as if we check we can't believably do that cause we c-bet all our draws on the flop.  But you really are not bluffing either, so I think checking the flop lets him fire draws/air/made hands, which is a little better than what he is calling the flop with, draws/air, and also you really don't want to make the pot big here out of position with a marginal hand.  The turn is a really good card for your hand, as it takes 2 of the 3 33 combos out of his range, so I would check call the turn as well, then probably check call river as it is a blank and he may have a hard time betting QJ and KJ for three streets of value here, so it makes his hands pretty much AJ, JJ, maybe QQ, or busted draws, making calling the river pretty profitable as there are more combos of busted draws and you are getting 3-1 on a call.  As played I call the river.  Oh also you should probably fold pre and save UTG stealing for hands like 76s that do well against calling ranges and are easy to get away from.
