If you can bank on UTG to make a continuation bet then checking is a fantastic play which can get you a whole shed load of dead money in the pot before it comes back round to you and you check raise. As it happened I'd be jumping for joy. I think call and then all in on the turn is the correct play if you want all of UTGs chips. Its very unlikely he is drawing to a straight with an UTG raise so you can disregard the negative side of giving a 'free' card. Pushing on the flop gives him a chance to get away from an overpair.

JJ will happen sometimes but not often enough to make not getting all your money in the correct play.
