Interestingly enough your a HUGE dog vs trips, but even if he has two pair with the Jack being the high pair like (3h 3d)Jh then the villain is still an 8% favorite over the hero's pair of A's.
I dont like how you played that street, raising is really spewing. In fact when you weigh the odds of his possible down card combinations it turns this hand into a fold.
