JJ Hand from Stars 20k last night

[Double Eagle]

60 Players Left so we are into the money, Avg Stack at 80k or so. Limper in this hand is weakish player, put him on ax with slight possibility of a monster. CO is a slightly loose but otherwise solid player. A little concerned about the possibility of an overpair, but think he could make the same play with TT, 99 or AK-AJ as a weak isolation attempt. I do not think he will fold to a Push. Three options here - Push, Fold or Stop and Go. Interested in thought processes here.....
