0.00139% Chance of Being Dealt a Straight Flush

Q: What are the Odds of Hitting a Straight Flush in Hold'em?

A: The "straight flush" is the second strongest hand in Hold'em (or Omaha), ranking behind only the "Royal Flush".

The "straight flush" occurs when a hand makes five consecutive cards, all of the same suit.

For instance - let's say that you are holding:

2 of spades
3 of spades

The flop comes:

Ace of spades
4 of spades
5 of spades

This is a "straight flush". In this situation, you would have the "stone cold nuts", which means the best possible hand.

So what are the odds of being dealt a "straight flush"?

Regardless of how many players are participating in a game of Hold'em, there are 36 hands that can make a straight flush (remember, we need to exclude the four hand that make a royal flush).

Now, there are 2,598,960 different hand combinations in Hold'em.

So, in order to calculate our odds of hitting a straight flush, divide the total number of straight flush hands (36) by the total number of possible hands (2,598,960) to get:

0.00139% chance of hitting a straight flush

or

1 in 72,192 chance of hitting a straight flush

-

While the "straight flush" isn't as hard as hitting a "Royal Flush", it still occurs very infrequently in the game of poker.
