You have 9¨8¨. There has been a bet before the flop which you called. The flop is A¨9§3¨. There is a bet. Against one opponent you must have either the best made hand or the only flush draw.
Such a possibility I refer to as an example of Morton’s Fork, after the income tax inspector in medieval times. He worked on the principle that if a member of the gentry were living in apparent poverty, he must be concealing his wealth. If he were living high on the hog, then he could again afford heavy taxes.
In such circumstances you are entitled to raise. You are either winning or have a strong drawing hand. Your opponent needs such as A-8 or A-A to be favourite against your holding. Even if the worst comes to the worst, you are better than 2/1 against winning the pot.
