- Whether you are new to poker or just looking for pre-flop range advice on which hands to play in certain situations, you have come to the right place. I have been playing and winning at poker since 2008 and have put together some charts for you. The chart will work well both online and live, in cash games and tournaments.
- Flopzilla is a poker calculator that has been designed to let you quickly and easily figure out how a range hits a board. Just enter a preflop range and a board and Flopzilla will work out for you how often that range hits hands like top pair, middle pair, a flushdraw, a gutshot, etc.
- Use -exhaustive or -e to run all preflop simulations. Note that this will take some time. Use -possibilities or -p to show all possible hand outcomes. Hand possibilities are shown by default if only one hand is defined. The method used to calculate probabilities can be imported and used directly in a JS/node project.
A poker odds calculator is a piece of poker software that lets you run any scenario that you might see at a poker table. You can fill in your own hand and calculate the chances of you winning. Working with poker hands is an excellent way to illustrate the counting techniques covered previously in this blog – multiplication principle, permutation and combination (also covered here). There are 2,598,960 many possible 5-card Poker hands. Thus the probability of obtaining any one specific hand is 1 in 2,598,960 (roughly 1 in 2.6 million).
In heads up poker games the rank (or strength) of starting hands change when compared to a 6 or 10 table game. This is due to the decreased likelihood that you are facing an opponent with a hand which dominates yours (is a 70% or more favorite against you). This article looks at how to calculate your odds pre-flop in heads-up poker and gives a list of the common pre-flop odds which every player should know.

There are a total of 1326 starting hands in Texas Holdem poker, this is calculated by taking 1 of the original 52 card deck and then one of the remaining 51 cards:
(1/52)*(1/51) = 1326 combinations.
If we leave aside the different combinations of suits then these can be reduced to 169 distinct starting hands. 13 of these are pairs, 78 are suited unpaired cards and the remaining 78 are unsuited unpaired cards.
The cards that you are dealt affect the probability of your opponent having the same holding. For example if you are dealt an Ace before the flop there are only 3 remaining aces in the deck – the chances of an opponent holding an ace has been reduced by 25%.
The table below shows the odds of being dealt specific strength holdings before the flop.
A-A (220/1 or 0.45%)
A-K (81.9/1 or 1.1%)
A-A, K-K, Q-Q or 10-10 (54.3/1 or 1.8%)
Any Pocket Pair (16:1 or 6.25%)
Any 2 Cards Jack or Higher (10.1/1 or 9.05%)
The relative strength of pre-flop hands in heads-up poker can be calculated by assuming that your opponent has a random holding. That is to say that the chances your hand will win a showdown if all the chips went in to the middle immediately can be ranked in terms of your holding compared to the whole range of your opponent's possible cards.

Range Equity Calculator
This calculator allows the user to calculate range vs range equity in texas hold'em poker. Simulate different board runouts and hole cards, and learn how different ranges are affected.
RangePoker Hands Odds Preflop Calculator Chart
The range panel allows the creation of an opening range. The range can then be examined using the tools on this page. The range can be created in three ways.
Text inputPoker Hands Odds Preflop Calculator Today
The text input uses shorthand text descriptors to define the range. Hands can be entered individually in a comma separated list (e.g. AA, AJo, 32s). Or as a sequence of hands using the + and - symbols. For example, 'T5o+' will add the hands T9o, T8o, T7o, T6o, T5o to the range. '96s-' will add the hands 96s, 95s, 94s, 93s, 92s to the range. And '66-99' will add the hands '66', '77', '88', '99'. Note that hands should be defined with the highest rank first, and unpaired hands should be specified as suited (s) or offsuit (o).
SliderThe slider defines a range based on a specific proportion of all possible hands. The hands are added in an order which favors hands with good preflop equity, however this does not necessarily correspond the hands which you or your opponents are opening, and it is recommend you make adjustments based on your experience.

GridThe grid allows the addition and removal of individual hands from the defined range. Add and remove hands by clicking on them.
SimulationWhen the simulate button is clicked, the program will take in the range of all the defined players and randomly simulate matchups between combos from their ranges. This will allow the estimation of the equity of each player, as well as the probability of tying (splitting the pot) and the pot odds.
If both hole cards are specified for any player, then the simulation will use the hole cards instead of the range.
If any part of the board is specified, then the simulation will only randomize the unspecified cards.

If any player is unchecked, then that player will not be considered in the simulation.
