Poker odds calculate the chances of you holding a winning hand. The poker odds calculators on CardPlayer.com let you run any scenario that you see at the poker table, see your odds and outs,. When playing poker, you will often find yourself on a draw after the flop. To decide how to play your draw, you should consider the pot odds, implied odds, reverse implied odds, and the chance of a redraw. Pot odds are fairly simple and the Pot Odds Calculator will help you with this. Pot odds means the odds you need to need to justify a call.
Aside from just being an awesome strategy resource, ThePokerBank (well, I), with the coding wizardry of my good friend Iain Lomas, also offers a bunch of free poker tools to help you improve your game. I call these the 'PokerBank Tools'.
They are lightweight, simple and they get the job done. More importantly, they are free, as I touched upon about 5 seconds ago.
I hope you enjoy them and if you have any ideas for other tools that I could offer, feel free to give me a shout.
Have these tools helped you at all?
If these tools help you to improve your poker game in any way, Iain would greatly appreciate a small donation as a thank you. Just a quick $3 or $4 for a beer on the weekend will go a long way!
I'm not going to lie, the donations will be deposited in to the beer fund rather than the 'tools production' fund. However, the sign of appreciation will certainly inspire and motivate for even more tools in the future.
Thanks in advance and I hope you enjoy the tools.

PokerBank web tools.
'What's that you say? Even more free tools?' I probably don't hear you exclaim. Nonetheless, here are a few more free web-based tools from ThePokerBank that you may also find useful.
Bankroll Calculator
Input the size of your current bankroll and the calculator will tell you four things:
- What stakes/level you should be playing at.
- How many buy-ins you have for that level.
- How far away you are from the next level (in buy-ins).
- A snippet of advice on how to play at the level you are bankrolled for.
It's a little different to the Fergulator tool, as Fergulator tells you how much you can safely buy in for at any level and when you should cash out. This bankroll calculator tells you what stakes games you should be playing.
Odds converter
Pot Odds Poker
Quickly convert between percentage odds (e.g. 35%) and ratio odds (e.g. 4 to 1) with this web-based poker odds converter.
The Poker Bank Pot Odds Game
It does exactly the same job as hoRatio – this is just like an online version.
Time to move up stakes calculator
This calculator estimates how long it will take before you can move up to the next level (or next 'stakes', whatever you want to call it) based on a few simple variables.
This particular tool is actually within a larger article, so just scroll down to the middle somewhere and you'll find it.
A few notes about these PokerBank Tools.
- They are Windows-only, so they'll fit right in alongside your favourite Windows 7 poker rooms. Or in other words, they won't work on your Mac or on your Linux OS. Sorry about that. However, they all work perfectly well under Parallels and WINE though.
- They are not buggy as far as I'm aware. I've used them a lot myself and they've been perfectly fine for me. They've not been designed to rape and pillage your PC, but just to cover my back, you download and use these tools at your own risk.
Enjoy.

In poker, pot odds are the ratio of the current size of the pot to the cost of a contemplated call.[1] Pot odds are often compared to the probability of winning a hand with a future card in order to estimate the call's expected value.

Converting odds ratios to and from percentages[edit]
Odds are most commonly expressed as ratios, but converting them to percentages often make them easier to work with. The ratio has two numbers: the size of the pot and the cost of the call. To convert this ratio to the equivalent percentage, these two numbers are added together and the cost of the call is divided by this sum. For example, the pot is $30, and the cost of the call is $10. The pot odds in this situation are 30:10, or 3:1 when simplified. To get the percentage, 30 and 10 are added to get a sum of 40 and then 10 is divided by 40, giving 0.25, or 25%.
To convert any percentage or fraction to the equivalent odds, the numerator is subtracted from the denominator and then this difference is divided by the numerator. For example, to convert 25%, or 1/4, 1 is subtracted from 4 to get 3 (or 25 from 100 to get 75) and then 3 is divided by 1 (or 75 by 25), giving 3, or 3:1.
Using pot odds to determine expected value[edit]
When a player holds a drawing hand (a hand that is behind now but is likely to win if a certain card is drawn) pot odds are used to determine the expected value of that hand when the player is faced with a bet.
The expected value of a call is determined by comparing the pot odds to the odds of drawing a card that wins the pot. When the odds of drawing a card that wins the pot are numerically higher than the pot odds, the call has a positive expectation; on average, a portion of the pot that is greater than the cost of the call is won. Conversely, if the odds of drawing a winning card are numerically lower than the pot odds, the call has a negative expectation, and the expectation is to win less money on average than it costs to call the bet.
Implied pot odds[edit]
Implied pot odds, or simply implied odds, are calculated the same way as pot odds, but take into consideration estimated future betting. Implied odds are calculated in situations where the player expects to fold in the following round if the draw is missed, thereby losing no additional bets, but expects to gain additional bets when the draw is made. Since the player expects to always gain additional bets in later rounds when the draw is made, and never lose any additional bets when the draw is missed, the extra bets that the player expects to gain, excluding his own, can fairly be added to the current size of the pot. This adjusted pot value is known as the implied pot.
Example (Texas hold'em)[edit]
On the turn, Alice's hand is certainly behind, and she faces a $1 call to win a $10 pot against a single opponent. There are four cards remaining in the deck that make her hand a certain winner. Her probability of drawing one of those cards is therefore 4/47 (8.5%), which when converted to odds is 10.75:1. Since the pot lays 10:1 (9.1%), Alice will on average lose money by calling if there is no future betting. However, Alice expects her opponent to call her additional $1 bet on the final betting round if she makes her draw. Alice will fold if she misses her draw and thus lose no additional bets. Alice's implied pot is therefore $11 ($10 plus the expected $1 call to her additional $1 bet), so her implied pot odds are 11:1 (8.3%). Her call now has a positive expectation.
Reverse implied pot odds[edit]
Reverse implied pot odds, or simply reverse implied odds, apply to situations where a player will win the minimum if holding the best hand but lose the maximum if not having the best hand. Aggressive actions (bets and raises) are subject to reverse implied odds, because they win the minimum if they win immediately (the current pot), but may lose the maximum if called (the current pot plus the called bet or raise). These situations may also occur when a player has a made hand with little chance of improving what is believed to be currently the best hand, but an opponent continues to bet. An opponent with a weak hand will be likely to give up after the player calls and not call any bets the player makes. An opponent with a superior hand, will, on the other hand, continue, (extracting additional bets or calls from the player).
Limit Texas hold'em example[edit]
With one card to come, Alice holds a made hand with little chance of improving and faces a $10 call to win a $30 pot. If her opponent has a weak hand or is bluffing, Alice expects no further bets or calls from her opponent. If her opponent has a superior hand, Alice expects the opponent to bet another $10 on the end. Therefore, if Alice wins, she only expects to win the $30 currently in the pot, but if she loses, she expects to lose $20 ($10 call on the turn plus $10 call on the river). Because she is risking $20 to win $30, Alice's reverse implied pot odds are 1.5-to-1 ($30/$20) or 40 percent (1/(1.5+1)). For calling to have a positive expectation, Alice must believe the probability of her opponent having a weak hand is over 40 percent.
Manipulating pot odds[edit]
Often a player will bet to manipulate the pot odds offered to other players. A common example of manipulating pot odds is make a bet to protect a made hand that discourages opponents from chasing a drawing hand.
No-limit Texas hold 'em example[edit]
With one card to come, Bob has a made hand, but the board shows a potential flush draw. Bob wants to bet enough to make it wrong for an opponent with a flush draw to call, but Bob does not want to bet more than he has to in the event the opponent already has him beat.
Assuming a $20 pot and one opponent, if Bob bets $10 (half the pot), when his opponent acts, the pot will be $30 and it will cost $10 to call. The opponent's pot odds will be 3-to-1, or 25 percent. If the opponent is on a flush draw (9/46, approximately 19.565 percent or 4.11-to-1 odds against with one card to come), the pot is not offering adequate pot odds for the opponent to call unless the opponent thinks they can induce additional final round betting from Bob if the opponent completes their flush draw (see implied pot odds).
A bet of $6.43, resulting in pot odds of 4.11-to-1, would make his opponent mathematically indifferent to calling if implied odds are disregarded.
Bluffing frequency[edit]
According to David Sklansky, game theory shows that a player should bluff a percentage of the time equal to his opponent's pot odds to call the bluff. For example, in the final betting round, if the pot is $30 and a player is contemplating a $30 bet (which will give his opponent 2-to-1 pot odds for the call), the player should bluff half as often as he would bet for value (one out of three times).
However, this conclusion does not take into account some of the context of specific situations. A player's bluffing frequency often accounts for many different factors, particularly the tightness or looseness of their opponents. Bluffing against a tight player is more likely to induce a fold than bluffing against a loose player, who is more likely to call the bluff. Sklansky's strategy is an equilibrium strategy in the sense that it is optimal against someone playing an optimal strategy against it.
