Since this is in the NL section I will give a NL answer. It is hard to determine the effective odds in NL. Since the opponent can bet any amount on the turn if you miss, you really have no way of calculating. You need to evaluate the pot odds on each street and see if you have correct odds to call a bet. To counter this, you have more fold equity from semi-bluffs. You can also put all the money in while ahead, thus allowing yourself to see 2 cards.
