I understand about playing it cautiously, but there is also playing playing it foolishly. JJ is still a very good preflop hand, whether you like it or not. Limping in with position isnt playing it cautiously, its too cautious and when you play that timidly, you are doing a disservice to yourself and this is probably why you stuggle playing it. Overcome your psychological aversion from JJ and play it like it more aggressively.

As for playing it for overpair and set value...well, you got your overpair and you ended up paying someone off...maybe you should rethink your preflop strategy and loosen up a bit...

Im with you though, i dont like JJ, but i still wouldnt limp in your position there.
