Tough spot? Villian has 600 and Hero covers, folding is not an option. You call her and see a flop, see what he does if it comes 10 high. If he checks make a bet, if he bets then proceed using caution. If you flop a set then there is a good chance you are getting alot of his money, but to fold that is the weakest thing I have heard.

Agreed - I don't think you can narrow CO range to only AA/KK - JJ and AK would also seem like real possibilities. You also have position on everyone here. Call and re-evauluate after the flop action.
