Also depends on your position.. make the minimal bet if 1st to choose. Either someone with an ace will call or raise. I occasionaly like to call that to tose out bait and see who bites. Then again they "may" think you have an ace. Once again depends on the circumstances of how many are playing, what type of players they are, and position. Yet if someone bets before you, more than likely they have the ace, not always.
