Preflop - Limping first time is shady at best, fold after the raise. I'll go further here - with that action to you - FOLD JQs.

Postflop - Calling is out of question. Reraise all-in or fold.
You've managed to get yourself in a situation where you have a hand that's not CURRENTLY best, but you have outs and the pot size is significant. It's a tough decision and requires some good reads on the villain to do a right move.

Pushing is a very minor +EV move here with no reads on the villain. Folding you're out t120 and hopefully learn not to call PF raises with cr@p hands.
