Limp / pat will probably look too fishy to not call with such a relatively small bet into the pot (though I don't know how short everyone else is).

I'd draw 4 to the jack (pair of jacks might be good given the action), but you're in bad shape against an overpair. I'd probably just check/fold if I don't hit big on the draw. 1000 chips isn't very much, but this is a really bad spot, and you are better off being all in on the big blind.
