Texas Holdem Preflop Odds Calculator

Our poker calculator is the perfect medium for finding out the odds in any given situation. Simply plug in your hand, your opponents’ hands, and the board, and you’ll be on the way to figuring out your next move. The Best Poker Hands Calculator. Poker rules are easier than you may think, and there’s no better time to learn how to play poker than now, as this popular American game is played by many people today. The basic rules of poker are the same, and use the same 5-card poker hand ranking chart. There is one obscure poker game, named Badugi Poker, that uses a 4-card hand ranking chart, but the general rules of poker still apply. To calculate your poker equity - or how often you should win a hand, you can use a simple formula. Count how many outs you have. For example, if you're drawing to a flush, you have 13 suited cards, two in your hand, two on the board - leaves 9 outs. The chance of you hitting on the turn is 9.4 (+4) = 40%.

Online, free poker hand range calculator for everyone. The odds are instantly calculated and displayed as a card is added to the table or the dead card grid. Great tool for improving Texas Hold’em strategy.

Useful information regarding Poker Hand Range Calculator

What is range in Poker?

A range is a combination of hands a player might have at a given time. Thinking about what players have in the form of a range is valuable because it allows you to think about all of the possibilities of a hand. Experts say that once you understand the idea behind poker range you will soon forget the way of thinking earlier. Thanks to our calculator developed by Forest Turner now you can easily learn flop textures and how ranges split up on boards, how equities shift on turn and river cards.

What you can see with our Poker Hand Range calculator?

The Poker Hand Range Calculator instantly show equities, combination counts, and hand value breakdowns. Use the reset buttons to start over the calculation. First, we start with a preflop range. Get started by selecting a preflop range for the scenario you are analyzing.

What is the highest hand and hands order in poker?

You can see the hands order below starting with the highest ending with the lowest:

• RoyalFlush: 10, Jack, Queen, King, Ace all in the same suit.

• StraightFlush: Five cards in a row, all in the same suit.

• Four of aKind: The same card in each of the four suits.

• FullHouse: A pair plus three of a kind in the same hand.

• Flush:Five cards, all in one suit but no numerical order (4, 9, 10, King, Ace in onesuit).

• Straight:Five cards in numerical order, but no same suit (4, 5, 6, 7, 8 with differentsuit).

• Three ofa Kind: Three of one card (3 Queens).

• Two Pair:Two different pairings of the same card in one hand (two Aces and two Jacks forexample).

• One Pair: Two cards of the same card (twoAces for example).

• High Card: If you have nothing the highest card plays.

Can somebody suggest me a good algorithm to calculate

No, because it isn't really an algorithm: it's an ordered list; and 10 seconds on Google got me this. If I was doing this, I'd probably consider using an Enum to define it though.

Apart from this i am also working on Pot creation and Rake calculation part. It would be helpful if anyone could contribute some logic or algorithms.

Again, the 'Pot' isn't really an algorithm; it's a structure - basically a List with methods for providing totals - and I reckon it's probably closely related to the Players at the table.
As for Rake calculation, you'll have to explain the term before I can help. Not a gambler.

Hi Winston,
Appreciate your help. Thanks. Yeah, http://www.pokerlistings.com/poker-hand-ranking this is actually the pattern that should be considered while calculating strength of cards.
For E.g. Consider simplest logic, If I am playing Poker Hand and
I got 5 cards as - 2♥ 7♦ 4 ♣ A♠ A♥,
Next person got 5 cards as - 5♥ 2♦ Q ♣ K♠ J♥,
here every card has a weight say 2♥- 23, 7♦ - 67, 4 ♣ - 98, A♠ - 122, A♥ - 109 then we have to create total and then compare both hands. The one with more weight wins the hand.
This is not really as simple as even i thought because there are millions of combinations possible with a hand (5 cards taken from a deck).
I am trying to implement this using pattern recognition, but that too is very lengthy.
Pot - yeah Pot is winning total at the end of poker hand, its not algorithm but we need to write some logic to calculate pot because:
1. Poker game can have number of Hands
2. Each Hand will add to the value of pot
3. Bets of each player will contribute to pot
4. Pot distribution depends upon the percentage of amount contributed by particular player to total pot amount
5. There can be one or more than one pot winners
I am done with the logic creation part for this.
Rake - Its the amount deducted from player whenever he bets some amount on table. It is the pivot of gambling where revenue generation happens. Can't disclose about it in details.

I don't that's what he's going for...
In standard Texas Hold 'Em, everyone is dealt two cards face down. there is a round of betting. You have to decide if to bet, and how much to bet, based on the two card. So being dealt a suited A-K is clearly going to be better than a non-suited 10-9. And an unsuited 2-7 is the worst possible starting hand.

Poker Hand Strength Calculator Equation

But even at that...your position at the table also has an impact. If you are in an early position, you need a stronger hand if you are going to bet, whereas if you are on the button, you can bet with weaker hand - depending on what everyone else does.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

Optional 'thank-you' note:

and 'Rake' isn't very complicated. It refers to how much money the house takes from each pot. It is generally only applied to casinos or on-line cash games. If you are playing at home with friends, there usually isn't one.
It can be done in any of several ways:
A fee to join the tournament
A percentage of each pot
A fee charged to the 'dealer' on each hand
Some online services charge a monthly fee (i.e. a subscription), but then play is 'free' beyond that
etc..

Doesn't sound right to me.
First: the problem is complicated by the fact that you're choosing the 'best 5 of 7' (actually: Player's 2, plus the best 3-of-5 from the flop, turn and river).
Calculator

Second: Any 'weighting' will only apply to:
(a) The value of card involved in making up two similar winning hands.
(b) The remaining cards of two identical winning hands.

I am trying to implement this using pattern recognition, but that too is very lengthy.

And possibly over-engineering. You only have 9 possible hands (10 if you count 'High Card', but personally I'd say that that's the

Texas Holdem Hand Strength Calc

absence of any other kind of hand) that fall into 3 categories:
1. Flushes - 5 cards of the same suit.
2. Straights - 5 cards in value sequence.
3. Multiples - 2, 3, or 4 cards of the same value (including full houses).
so I'd make those your first checks.
I'd also do them in the order above because in 'vanilla' form, that's the order they're ranked. And unless you're playing from a multi-deck shoe (unusual, from what a gather), it also eliminates the most possibilities:

If you find a flush in the 7 possible cards, it must be the best hand available to the player. So, the only other thing you need to check is:
Are those same 5 cards (or a particular set, if there's more than one combination to choose from) ALSO a straight?

If you don't find a flush, but DO find a straight, again, it must be the best hand available to the player.

If you don't find a flush, or a straight, the only other possible hand is a multiple (or twin-multiple) of some kind. I'll leave you to sort out that logic, but it's still relatively straightforward.

With a multi-deck shoe, it's a bit trickier, but still relatively straightforward. The main difference is that if you find a flush; the 7 cards could ALSO contain 4 of a kind or a full house.

Oh, OK. I was thinking of weighting in terms of Poker hand strength calculator equation

final evaluation. Seems to me that weighting (especially by card) probably isn't the way to go for evaluating a hand (or, more accurately, a 'situation'), since there are so many other variables - including the 'weight' that you might put on any previous bet placed, particularly if the game involves 'blinds'.

Thanks Winston. Actually the game being developed will go live for real money poker gaming; at early stage we are expecting around 1000 players playing online at the same time while approximately 200 just logged in and watching game. The knowledge you shared was really helpful.

Optional 'thank-you' note:

Winston is correct in that there is no real need to calculate hand strength until the very end of the hand where you are forced to determine the winner (showdown). For human players playing against other human players this will be sufficient as long as your program knows how to read the player's hands and evaluate them based on the list of hand rankings, flush beats straight for example.
If you're developing a poker playing artificial intelligence or if you're just curious you may want to look into starting hand strength from a strategic standpoint. As was pointed out, in texas holdem an ace and a king is a better starting hand than a two and a seven. One way to determine this is by running both hands through an equity simulator, which is a program that runs hundreds of thousands of different possible boards out that allows you to get a pretty accurate estimate as to which hand wins more often. Then you can run each hand against each other possible hand, determine an average equity and then rank the hands accordingly. There are two great free programs out there that do this already:
PokerStove
ProPokerTools
Its still however, ultimately a matter of strategy that determines what the best hands are and not programming since there are different betting streets and different player psychologies.
TwoPlusTwo is a great strategy site that also has a programming forum.

I created somthing similar a while ago, it wasnt very nice coding.. but it was something fun to do.
ANyway have you looked at bill chen formula, that is very easy to convert into an algorithm. Il also try and find the site i used, it was a points scale basically, which would tell me whether i should raise or fold..etc..etc.. not sire if that what your lookign for.
