PJ's could be a nasty hand, i know i was in this position, i raised pre flop; flop came 2 over cards and and 2, i folded when opp raised. you didn't mention any suits i'm assuming rainbow? if you wanted to be itm, you probably should play it safer, it has happened to me to get soo close and the time invested- it almost makes you sick. i've folded premium hands when the raising was out of control, it's better but hard till you know you have a monster, and it's not going to effect your image many have played it save towards the end and freeze up. when i've praticed the patience and control of my moves, that is the only time (towards the end) that i've come itm.
beter luck next time.
