I have been told that an ace can be used at the bottom of a strait even if the lowest card is not a 2. Is this true? For example: 9,8,7,6,A...is this an actual poker hand?
That's a hand but not a straight. That's an ace high. An ace can be used at the bottom end of a wheel (slang for a five high straight), A-2-3-4-5 or at the top end of an ace high straight such as 10-J-Q-K-A. It cannot be used to fill in any other straights with conventional poker hands.
