A poker hand with all 5 cards in sequence by rank. A - K - Q - J - 10 is the highest straight and is known as "broadway". 5 - 4 - 3 - 2 - A is the lowest possible straight and is known as the "wheel". Straights cannot wrap around the Ace in No-Limit Hold'em. Example: 3 - 2 - A - K - Q is not a valid straight.
