Use Bet Shrew Poker Odds Calculator to calculate the odds of making a hand while playing Texas Hold‘em poker.
Poker is a game of incomplete information as you do not have access to your opponent's hole cards while making your betting decisions. Unlike other online Poker Odds Calculators, the Bet Shrew Poker Odds Calculator reflects this and calculates your odds based only on the cards that you can see.
The Bet Shrew Poker Odds Calculator is perfect for beginners and intermediate players wanting to calculate their draw odds and outs quickly and accurately without any complicated maths.
The various odds tables that you may encounter while using the Bet Shrew odds calculator are explained below.
Starting Hand Odds
Before you have even been dealt your hand, the calculator will show you the odds of being dealt different possible starting hands. For example, it will show you the odds of being dealt pocket aces (note: this can be applied to any specific pair).
These odds can be particularly useful when you are short stacked, waiting for that all-in opportunity.
Draw Odds
When you specify your hole cards, the calculator will consider every possible combination of cards that can still be drawn from the deck, evaluate what hand you would make for each possible combination and calculate the odds of you making each hand.
The draw odds table will breakdown your odds of making a hand on the flop, by the turn and by the river.
Odds of a Higher Poker Pair
When you have a pocket pair, the Poker Odds Calculator will show you the odds of an opponent holding a higher pocket pair.
The odds of an opponent holding a higher pocket pair is dependent on how high your pocket pair is and the number of players at you table. The odds presented will automatically consider the cards you are holding and then show you a breakdown of the odds based on the number of players.
Please note that these odds are based on the number of players at your table, not the number of players in the hand. This is important to note because a player at your table could be dealt a higher pocket pair but fold.
Odds of an Over Card
The odds of an over card table shows the odds that a card with a higher value than your highest denomination card will be drawn on the board.
Knowing the odds of an over card being drawn allows you to bet an appropriate amount to price out players fishing for a higher pair.
To set your hole cards or any community cards, simply click on the card you wish to set from the deck. As you click on cards from the deck, first your hole cards will be set, followed by the flop, the turn and then the river. As you set the cards in the hand, draws odds will automatically be calculated and displayed.
To unset a card, simply click on it to return it to the deck. Clicking the new hand button will reset the whole table and allow you to calculate the odds for a new hand.
How are draw odds calculated?
To calculate your draw odds, the calculator generates every possible combination of cards that could be drawn from the deck. For each combination, it evaluates the best 5 card hand that can be made and tallies up how often that a hand is made. This yields the precise probability of making each hand type.
This is a computationally expensive process. For speed and performance benefits, draws odds have been pre-computed and stored. This means that rather than recalculating draw odds every time, the calculator only needs to lookup the correct values from a table; albeit a very large table.

Why are the draw odds different to what I expected?
Calculating draw odds is tricky. To understand how and why the odds above may not be quite what you expected it is best to use an example.
Let's say that you have AS and KS in your hand and you want to know the odds of making a pair on the flop. There are 6 cards that can make you a pair (3 Aces and 3 Kings).
To calculate your odds you may intuitively say that the odds of drawing an Ace or a King as the first card of the flop is 6 divided by the 50 remaining cards in the deck and you would be correct.
For the second card of the flop you might be inclined to say that it would be 6 divided by the 49 cards remaining in the deck. However, you must also consider what impact the first flop card made on your odds. This is where the math can get tricky.
Let’s say the first flop card is a 7D. If the second flop card is any other 7, even though you have not paired your hole cards, the hand you have made is still a pair; a pair of sevens.
Using the same example of AS, KS, another consideration is what if you make a better hand like 2 pair or 3 of a kind?
If the first of the flop cards is an Ace, great you've made top pair! However, if another Ace or a King comes you have no longer made a pair you have made a better hand.
The Bet Shrew odds calculator factors these consideration in as it determines every possible combinations of cards that could be drawn, evaluates the best 5 card hand that can be made and aggregates the results to determine their probabilities.
