What is Straight? In Poker, Five cards in a sequence is called Straight.

A♠KQ♣J10 is the highest (Ace high) straight

A2♣3♠45  is the lowest (Five high) straight.

A straight is a hand that contains five cards of sequential rank, not all of the same suit, such as 8♣ 7♠ 6♠ 5 4 (a "Eight-high straight"). It ranks below a flush and above three of a kind. Under high rules, an ace can rank either high (as in A K♣ Q♣ J 10♠, an ace-high straight) or low (as in 5♣ 4 3 2 A♠, a five-high straight), but cannot simultaneously rank both high and low (so Q♠ K♠ A♣ 2 3 is an ace-high hand).

Under deuce-to-seven low rules, an ace always ranks high (so 5 4♠ 3 2♣ A is an ace-high hand). Under ace-to-six low rules, an ace always ranks low (so A♣ K♠ Q♠ J 10♠ is a king-high hand). Under ace-to-five low rules, straights are not possible (so 10 9♠ 8♣ 7♣ 6 is a ten-high hand).

Each straight is ranked by the rank of its highest-ranking card. For example, J 10 9♣ 8♠ 7 ranks higher than 10♠ 9♠ 8♣ 7 6♠, which ranks higher than 6♣ 5♠ 4 3♠ 2. Straight hands that differ by suit alone, such as 9♣ 8♣ 7♣ 6 5 and 9♠ 8♠ 7♠ 6 5, are of equal rank.

An ace-high straight, such as A♣ K♣ Q J♠ 10♠, is called a Broadway straight,while a five-high straight, such as 5♠ 4 3 2♠ A♥, is called a baby straight, bicycle or wheeland is the best possible hand in ace-to-five low games (where it is a high card hand, not a straight).

#### Straight Hand Probabilities

If you are dealt five cards, there are 4 × 10 = 40 possible straight flushes ( 4 × 9 = 36 if you exclude royal flushes) out of the ( 52 5 ) = 2598960 possible hands. So the probability is 40 / 2598960 = 1 / 64974 ≈ 0.00001539.

The probability of getting straight increases if you can have more than 5 cards to choose from. The probability that somebody will have a straight flush will increase if the number of players increases. It may reduce if you might drop out of the betting before seeing all five cards.
