I've played a few hands new to the table at a 2/5 casino game and have JJ UTG with about 520 behind. I limp in EP, MP regular LAG flats, the CO raises to 20 and the button quickly 3bets to 100 everyone folds to me, I flat, MP folds, and then CO the shoves AI for 453. The button and the BB have been active at the table so I tried to disguise the strength of my hand with a more passive line. Is this a preferable line than opening UTG where someone's 3 bet range would be more defined vs an UTG range? The CO line is so strong that I would fold JJ here easily.
