Offer to sell your hand to BB for $5 and a beer. If he refuses, fold.

fold why invest 3 bets out of position with JTs. and it is possible even for bad players to pick up real hands, and to reraise. i think this has neg ev, especially out of position.

This is one of those hands that tempts against weak opposition, but I dont think your postflop edge could be enough because you have the twin evils of being out of position and having a hand that cant win a showdown unimproved.
