With aces your best hope is to get heads-up and hope you don't get outdrawn though as I've always said and others have said before me, when you lose with aces, you lose big. A big raise or re-raise means you have declared your hand, so unless you flop at least a set you could be in trouble if the other guy flops a set or even two pair.Depends on the flop, the size of the bet and how many villains are trying to steal the pot.
