What is a Poker Odds Calculator?


Poker players looking for a way to tip the odds in their favor, resort to a variety of techniques, gadgets and programs. While many of these methods turn out to be bogus, or too complicated to understand, the development of poker odds calculators have proven helpful to serious poker players.

Poker odds calculators come in two basic forms: software programs that you can purchase or download from a producer's website to your home computer; and pocket calculators that allow you to take the odds calculator with you wherever you go, except the casino floor, of course. Either type of poker odds calculator presents the poker player with the statistical odds and risks of betting on a particular hand based on how many players are at the table, the point of play in the game, and the existing cards already dealt.

The poker odds calculators are created by a complex set of algorithms, which compute the chances of winning based on past computations - the odds that this particular combination of cards will come up at a particular point in a game. While this information may seem to be too expansive to ever be able to commit to memory, there are some very basic odds that can be memorized by rote. Most successful poker players have educated themselves on the basic theories of odds so they can make snap decisions based upon those statistics regarding the chances of hitting a hand, as quickly as the cards are dealt.

Poker has a long history, and it has recently been experiencing a resurgence of interest because of the high-stakes poker games hosted in famed gaming casinos. The World Poker Tour began televising Texas Hold 'em tournaments in 2003 and this has further popularized the game.

Other popular poker games include: draw; five-card stud; seven-card stud; Omaha; and Manila. While the original card game may have begun hundreds of years ago in Europe or Persia, conventional wisdom contends that the modern game of poker originated on the riverboats that ferried the gentry and the much-maligned "professional card player" up and down the Mississippi River during the early 1800s. As the westward expansion opened up the new frontier, the game of poker became a popular pastime to ward off the isolation and loneliness of men separated from their families, and without the diversions of the cultured east.

Today, the odds of being dealt a winning hand are no better than the chances during the Wild West times. Luckily, savvy poker players can now avail themselves of poker odds calculators that can at least more precisely compute the stats in order for you to know the chances of getting that winning hand-and winning the pot.

Although you may not be allowed to bring a poker odds calculator with you to to the table at a tournament, the use of one in more informal settings can be very beneficial. Playing games on the computer with a poker odds calculator can provide you with the experience to perform approximate calculations on your own.

Both your KT and the guy's AA are dead hands. The guy who called the aces really should have complained. It affects him in a real way. If he beats AA, chances are he beats any other hand that might call, so any extra money that goes into the pot just increases his "pot odds". This is why AA can't show his hand. It has a negative impact on the other player.

To the second part, you don't actually provide an answer, nonetheless, I can say that you would have come to the wrong answer. (For the sake of my discussion, I am going to ignore the fact that you know a third guy has a flush draw. Yes, his cards would influence the final answer). You make the false assumption that no one threw away a Q, J or 9. You say that there are 30 cards left (there are actually 31) but you make the assumption that your opponent has his full allotment of outs. You should assume that you know nothing about the cards you didn't see.

This leaves your opponent with 7 out of 45 cards to hit on turn, and 10 out of 44 on river. Now if he hits on turn or river you are drawing dead, so your odds of winning are 1 - 7/45 - (1-7/45) * 10/44. I hope this helps. Cheers!


This is a 1-2Nl cash Game:

If I flop a king high straight,(flop is Jack, Queen, Nine, (queen and Jack are hearts) I have King(clubs) and Ten (spades) and the player first to bet goes all in. I call out of turn and show my Straight. However I did this out of turn because there is a player in front of me yet to call.

He has a two hearts in the hole. The guy who went all in states my hand is dead, because I did this out of turn. I state in a cash game you can show your cards any time if you are all in.

I do agree in tournament play this would be a dead hand. Who is correct?

I say I am because I saw this happen on high stakes poker once.

This is what happened: a guy goes all in with aces pre-flop. The first guy calls with five other players yet to make a call. The guy with aces flips them over to show everyone yet to call what he has. He states he did this to isolate only on one player not go into a hand with six players calling an all-in.

Everyone else folded. It did not seem to be a big deal.

I would like to hear an answer on this from someone who plays in the casinos.

Next part of this: the player with the flush draw folds and then with the best hand I am now up against a set of jacks!

What are the odds I am going to lose to a full house on the turn and then on the river?

This game has a total of nine players, so I figure there are before the turn 22 cards that are out with 30 cards remaining. My way of thinking is on the turn I can be beat by seven outs, so 7 out of 30 is 24 percent. Then on the river, the set now has 10 outs with 28 cards left -- about 35 percent.

So am I correct in the way I am doing my math?
