I'd play hand 1 faster. You'll get action from most Ax hands, all 6x hands, maybe even flush draws. You can't be serious about getting away from the hand. Sure you ran into JJ here, but come on. It's a cooler. This is exactly the sort of hand you want to stack off with. As played, you might be getting action from AK, AQ, AJ, 6x. Even this opponent might play AJ, 6x this way. Ironically, playing to get your stack in by leading the flop likely would have pushed off this particular opponent from his JJ.

Hand 2: Why are you playing so fast here? Here you have a decent made hand, but a huge draw too. What might your opponent have? A weak ace? A small flush draw? AQ? AJ? 22? Maybe KJ? Your flop raise is scaring off the hands you are beating and keeping around the hands that beat you. Plus, you want flush draws to draw with you and donate chips to you along the way. You can even price these hands in along the way with a small bet if they check to you on the turn.
