Hand 1: Since you have 2 aces AJ isn't likely. Other jacks going crazy like this on the turn seems unlikely. Semi-bluff is unlikely. I give unknowns less credit, but this hand smells like a set. As played except folding to the all in.

Hand 2: I'm probably 3 betting the flop just because he has some straight draws in his range along with 88-QQ. Not sure if it's good though.
