Assuming your oppenent has JJxx or any other set, you are about 50% to win if you push on the flop. If i were you, i would push all-in on flop, he could also be betting with a wrap/mid flush draw which would make you way ahead. Whatever falls on the turn your pushing all-in anyway, unless the board pairs. The best possible hand u could be up against is JJQT and even then its 40/60. Push the flop.
