just call. if he has aces and no K or A hits you're likely to be stacked 'cause you're outta position, but you're giving yourself a much better opportunity at getting value from AJ and JJ and KQ and such.

as a side note i'll definitely post from CO. if i get J9o, i don't raise and if the flop doesn't come two pair or better then i stay outta the hand. i really don't think i'm costing myself much money doing this (who's to say that having to play your first two hands OOP AND having to post a combined 1.5bb is any better?!)
