Poker Hands Ace Low Straight
Every poker player knows that the Royal Flush is the strongest poker hand, but where do all of the other poker winning hands rank? Here is a comprehensive list of poker hands in order from highest to lowest ranking. If you are new to the game of poker, learning the different poker hands is a great first step in learning how to beat your opponents with the cards you are dealt.
On the poker hand rankings chart, a Straight weighs in at fifth position. Directly above a straight is a Flush poker hand. The best flush you can form is an Ace-high Flush. In a standard game of Texas Hold’em poker, a Straight is still a great hand to form. Poker Hand Combinations Explained. Poker hands fall into one of ten categories. The highest is a royal flush, followed by a straight flush, then four of a kind, a full house, a flush, a straight.
#1 Royal Flush
In Hi/Lo poker an Ace counts as a low card when you are calculating the low part of the board. In fact, the Ace is the best possible low card, then the Deuce, then the Trey. Thus the Ace is doubly important in Hi/Lo games it is the best card for the low side of the pot as well as for the high end. A2345 is the lowest possible straight, also sometimes called a 'wheel.' In any other context, aces will be ranked higher than other cards. As in a regular straight, you can have an ace either high (A-K-Q-J-T) or low (5-4-3-2-1). However, a straight may not 'wraparound'. (Such as K-A-2-3-4, which is not a straight). An Ace high straight-flush is called a Royal Flush and is the highest natural hand. Four of a Kind Four of.
The strongest poker hand is the royal flush. It consists of Ten, Jack, Queen, King, and Ace, all of the same suit, e.g. diamonds, spades, hearts, or clubs.
#2 Straight Flush
The second strongest hand in poker is the straight flush. It is composed of five consecutive cards of the same suit. If two players have a straight flush, the player with the highest cards wins.
#3 Four-of-a-kind
A four-of-a-kind is four cards of the same rank, e.g. four Aces. If two players have four-of-a-kind, then the one with the highest four-of-a-kind wins. If they have the same (if four-of-a-kind is on the board), then the player with the highest fifth card wins, since a poker hand is always composed of five cards.

#4 Full House
A full house is a combination of a three-of-a-kind and a pair. If two players have a full house, then the one with the highest three-of-a-kind wins. If they have the same one, then the pair counts.
#5 Flush
Five cards of the same suit make a flush. If two players have a flush, then the one with the highest cards wins.
#6 Straight
Five consecutive cards are called a straight. If two players have a straight, the one with the highest cards wins.
#7 Three-of-a-kind
A three-of-a-kind is composed of three cards of the same rank. If two players have the same three-of-a-kind, then the other cards, or both cards, determine the winner, since a poker hand is a always composed of five cards.
#8 Two-pair
Two-pair hands are, of course, composed of two pairs. If two players have two-pair, the rank of the higher pair determines the winner. If they have the same higher pair, then the lower one counts. If that is also the same, then the fifth card counts.
#9 Pair
A pair is composed of two cards of the same rank. Since a poker hand is always composed of five cards, the other three cards are so-called “kickers”. In case two players have the same pair, then the one with the highest kicker wins.
#10 High card
If you don’t even have a pair, then you look at the strength of your cards. If there are two players at showdown who don’t have a pair or better, then the one with the highest cards wins.
Any of the PalaPoker.com games use the standard rank of hands to determine the high hand.
However, at PalaPoker.com we also play “split pot” games, like Omaha Hi-Lo8 and Stud Hi-Lo8, in which the highest hand splits the pot with a qualifying (“8 or better”) low hand; therefore, we must also be familiar with:
Low Poker Hands List:
This method of ranking low hands is used in traditional Hi/Lo games, like Omaha Hi/Lo and Stud Hi/Lo, as well as in Razz, the ‘low only’ Stud game.
Note that suits are irrelevant for Ace to Five low. A flush or straight does not ‘break’ an Ace to Five low poker hand. Aces are always a ‘low’ card when considering a low hand.
Please also note that the value of a five-card low hand starts with the top card, and goes down from there.
#1 Five Low, or “Wheel“: The Five, Four, Three, Deuce and Ace.
In the event of a tie: All Five-high hands split the pot.
#2 Six Low: Any five unpaired cards with the highest card being a Six.
In the event of a tie: The lower second-highest ranking card wins the pot. Thus 6,4,3,2,A defeats 6,5,4,2,A. If necessary, the third-highest, fourth-highest and fifth-highest cards in the hand can be used to break the tie.
#3 Seven Low: Any five unpaired cards with the highest card being a Seven.
In the event of a tie: The lower second-highest ranking card wins the pot. If necessary, the third- highest, fourth-highest and fifth-highest cards in the hand can be used to break the tie.
#4 Eight Low: Any five unpaired cards with the highest card being an Eight.
In the event of a tie: The lower second-highest ranking card wins the pot. If necessary, the third-highest, fourth-highest and fifth-highest cards in the hand can be used to break the tie. An Eight Low is the weakest hand that qualifies for low in Omaha Hi/Lo and Stud Hi/Lo.

I recently took a Hackerrank challenge for a job application that involved poker. I'm not a poker player, so I had a brief moment of panic as I read over the problem the description. In this article I want to do some reflection on how I approached the problem.
The hackerrank question asked me to write a program that would determine the best poker hand possible in five-card draw poker. We are given 10 cards, the first 5 are the current hand, and the second 5 are the next five cards in the deck. We assume that we can see the next five cards (they are not hidden). We want to exchange any n number of cards (where n <= 5) in our hand for the next n cards in the deck. For example, we can take out any combination of 2 cards from the hand we are given, but we must replace these two cards with the next two cards from the deck (we can't pick any two cards from the deck).
Suit and value make up the value of playing cards. For example, you can have a 3 of clubs. 3 is the value, clubs is the suit. We can represent this as 3C.
Suits
Clubs CSpades SHeart HDiamonds D
Value (Rank)
2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, Ace
Hands
Here are the hands of poker
Royal flush (the problem didn't ask me to consider Royal Flush)
A, K, Q, J, 10, all the same suit.
Straight flush
Five cards in a sequence, all in the same suit. Ace can either come before 2 or come after King.
Four of a kind
All four cards of the same rank.
Full house
Three of a kind with a pair.
Flush
Any five cards of the same suit, but not in a sequence.
Straight
Five cards in a sequence, but not of the same suit.
Three of a kind
Three cards of the same rank.
Two pair
Two different pairs.
Pair
Two cards of the same rank.
High Card
When you haven't made any of the hands above, the highest card plays.In the example below, the jack plays as the highest card.
Evaluating a hand of cards
A hand is five cards. The first thing I did was write out functions to evaluate if a group of 5 cards satisfies the conditions of one of the ten hands.
Here's a sample hand:
To write functions, I reached for using 2 important python features: set and defaultdict.
Here's an example of a simple function to detect a flush, a hand with cards of all the same suit:
Checking a flush
This function creates a list of the suits in our hand, and then counts the unique elements in that list by making it a set. If the length of the set is 1, then all the cards in the hand must be of the same suit.
But wait, what if we have a straight flush? Also, a hand that satisfies a flush could also be described as a two pair hand. The problem asked me to find the highest possible hand for a given set of cards, so I tried to keep things simple by writing a check_hand() function that checks each hand starting from straight flush down to high card. As soon as a condition for a hand was satisfied, I returned a number that corresponded to the strength of the hand (1 for high card up to 10 for straight flush). The problem didn't include Royal flush, so I will not include that here.
Here's the check_hand function:
This function starts checking the most valuable hands. After it checks the second to lowest hand (pair), it returns a value of 1. This value of 1 corresponds to the 'highest card' hand. Since I'm not comparing the relative value of hands, it doesn't matter what the highest card is, so the number just represents the type of hand that is the strongest.
Other hands
Here are the all of the functions I used to detect hands:
defaultdict is a great built-in that is good to use when you don't know what elements will be in your dictionary, but you know what the initial values of any key that could be added should be. We don't need it here, but the alternative would be to write a very long dictionary where keys are the possible card values and the values of each key is 0.
It would certainly be cleaner and more efficient to write out the above functions into one large function, but I wanted to keep things simple as I was under time constraints.
The next step in the problem is to determine the best possible hand we can get given the hand we are dealt and the 5 cards on top of the deck. I decided to first solve this problem with brute force. Here was my logic for this part: use itertools to get all combinations of groups of 0, 1, 2, 3, 4 and 5 cards from my hand and add the first 5 - n cards from the deck so we get a five card deck. For each combination of cards we can run check_hand() and keep track of the highest rank hand, and then return that hand as the best hand. Here's the code I wrote for this part of the problem:
Lastly, I need to check each hand and print out the best hand possible. Here's the loop I wrote to do this:
This will accept one round of cards per line:
and it will output the following:
This was an interesting problem to deal with as the solution contained several parts that worked together. While solving the problem I aimed worked through to the end leaving some parts to come back to that I felt confident in solving. Instead of writing each function to check differnt hands at the beginning, I filled most of these functions with pass and moved on to write the next part that involves checking each different combination of cards. Recently having worked through python's itertools exercises on Hackerrank, the combinations functions was fresh in my mind.
While I was able to arrive at a solution that satisfied the test cases, I did not have time to think about the efficiency or Big O analysis of the problem.
There is obviously some refactoring that I could do to make things cleaner. With more time I would take an object oriented approach by making classes for cards and hands, and adding class methods to evaluate the hands.
For each round, we have to run check_hand() on each hand combination. Let's think about how many hands we have to evaluate:
We have to consider combinations of cards formed by taking out groups of 0, 1, 2, 3, 4 and 5 cards and adding the next number of cards in the deck that bring the total card count to 5, which means we have to do 5C0 + 5C1 + 5C2 + 5C3 + 5C4 + 5C5 calls to check_hand(). So the sum of total calls is 1 + 5 + 10 + 10 + 5 + 1 = 32.
Poker Straight Ace Low
For each of these 32 calls that happen when we run play(), check_hands() runs through each of the check_ functions starting with the highest value hand. As soon as it finds a 'match', check_hands() returns a number value (hand_value) corresponding to straight flush, four of a kind, etc. This value is then compared with the highest value that has been previously found (best_hand) and replaces that value if the current hand's hand rank has a higher value.

I'm not sure if there is faster way to find the best hand than the brute force method I implemented.
