I always have trouble in spots like this too.

My first instinct is to call the flop and then raise a safe turn card (assuming CO bets again), but it depends on how aggro CO is post-flop. IF he could be betting with overcards or a flush draw or something, then I think raising the turn could be good, because if EP or hijack have a ten or something, they might fold the turn to 2 bets cold (even bad players will do this pretty often in a spot like that, I think).

If, however, CO's flop donk means he has at least a pair, I would call the flop with the intention of calling the turn (or possibly folding, depending on the rest of the flop action and the card) if you don't improve...raising the flop isn't likely to get you heads-up anyway, so you might as well see the next card cheaply.
