Hand types straight, flush, three-of-a-kind, etc are roughly arranged in poker so that more likely hands beat less likely hands though the likelihood difference between straights and flushes is really small. Within hand types, ties are broken by rank.

AA beats 88 beats 22; Ace-high flush beats king-high flush. This is true of straight flushes as well: You could imagine a version of poker where any pair was as valuable as any other pair, any straight as valuable as any other straight, etc.

Although in general, rarer poker hands beat more common poker hands, this is not always the case. As others have pointed out, a pair of aces is exactly as likely as a pair of twos, but the game is more fun if different pairs are more valuable, because it makes boring draws less likely. However, with flushes in general, more common flushes are more valuable than rarer flushes. An ace-high flush is the most likely to occur, since given the ace, there are twelve other cards to choose from to make up the rest of the flush discounting only the KQJT to make a royal flush , so this can be made in a total of 11, ways.

A seven high flush is the rarest, it can only be made in four ways , , , But the rules of the game are constructed to avoid draws where possible and ace-high flushes beating king-high flushes is consistent with a pair of aces beating a pair of kings. Just since nobody else has mentioned it yet: And it is in fact the case that the higher a type of hand is ranked like straight, flush, full house, etc. This is consistent for all hand types. As others have mentioned, there needs to be a way to break ties in case two players have the same hand type, which is when the deuce through ace value ranking comes into play.

Yes, it's fair, if your playing high card poker. There are forms of poker where low cards win, and in some of those game variations, a wheel A-5 straight will beat broadway T-A straight or a steel wheel A-5 straight flush is the absolute nuts best hand possible.

Your correct that hitting those hands is the same odds. It's also true getting a pair of threes is the same odds as getting dealt a pair of aces, but most of the time and in most games, the aces are far more valuable. Without card rankings, things can get very confusing. It's a subtle point, but you are actually MORE likely to get a royal flush in Texas Hold'em than you are to get any other straight flush! But how many ways can you have a KING high straight flush? And the same applies for the wheel - if you have the wheel straight flush, you can't also have the six in the same suit, or else you have a six-high straight flush, not a wheel straight flush.

Very interesting way of looking at it. The odds of getting any pair are all the same. The odds of getting any flush are all the same. However, in order to decide who wins a pot and not having spilt pots over and over again we use the ranks of the hand.

The chances of getting a pair of fives is the same as getting a pair of nines. But, we decide before the game begins that the pair of nines wins the hand. There are 10 straight flushes possible in each suit. A total of 40 hands. In the unlikely event that two people have one at the same time we use the tie breaking procedure of: A straight flush to the King 9, 10, J, Q, K is the second highest. And so on, right down to the Ace, 2, 3, 4, 5 which is the lowest.

The royal flush has a higher value,just as AA beats KK. This page may be out of date. Save your draft before refreshing this page.
